Assets can be bought and sold on asset exchanges. An exchange can maintain a database of orders that are awaiting execution.
A system that includes at least one processor and at least one memory communicatively coupled to the at least one processor is disclosed. The system also includes at least one network interface communicatively coupled to the at least one processor and configured to receive information regarding a plurality of order books from a plurality of asset exchanges. The at least one processor is configured to receive the information regarding the plurality of order books for the plurality of asset exchanges from the at least one network interface. The at least one processor is also configured to update a consolidated order book based on information regarding the plurality of order books for the plurality of asset exchanges and for local orders received from users of the system. The at least one processor is also configured to track any resting orders on the plurality of order books from the plurality of asset exchanges and any local resting orders resulting from local orders received from users of the system.
When a new order is received from a user of the system, the at least one processor is configured to determine whether the new order matches any orders in the consolidated order book. When the new order does not match any order in the consolidated order book, the at least one processor is configured to place the new order in at least one of the consolidated order book, a separate local order book, or at least one of the plurality of order books of the plurality of asset exchanges. When the new order matches an order in the consolidated order book that corresponds to a particular order on a particular order book of a particular asset exchange of the plurality of asset exchanges, the at least one processor is configured to communicate a custodial order to the particular asset exchange to attempt to match the new order on the particular asset exchange using custodial assets for the user of the system. When the custodial order matches the particular order on the particular asset exchange and a transaction of the custodial order and the particular order on the particular asset exchange is executed using the custodial assets for the user of the system, the at least one processor is configured to remove the new order from the consolidated order book corresponding to the particular order on the particular asset exchange. When the custodial order does not match the particular order on the particular asset exchange or the transaction of the custodial order and the particular order on the particular asset exchange is not executed, the at least one processor is configured to place the new order in at least one of the consolidated order book, a separate local order book, or at least one of the plurality of order books of the plurality of asset exchanges.
Understanding that the drawings depict only exemplary embodiments and are not therefore to be considered limiting in scope, the exemplary embodiments will be described with additional specificity and detail through the use of the accompanying drawings, in which:
In accordance with common practice, the various described features are not drawn to scale but are drawn to emphasize specific features relevant to the exemplary embodiments.
In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific illustrative embodiments. However, it is to be understood that other embodiments may be utilized and that logical, mechanical, and electrical changes may be made. Furthermore, the method presented in the drawing figures and the specification is not to be construed as limiting the order in which the individual steps may be performed. The following detailed description is, therefore, not to be taken in a limiting sense.
Assets can be traded (e.g., bought and sold) on asset exchanges. This includes two corresponding orders (e.g., buy 10 units, sell 10 units) being first matched with each other, then executed. One difficulty with asset exchanges can be matching orders together before execution. In examples, multiple asset exchanges may execute orders for an asset, e.g., securities, bonds, fiat currency, cryptocurrency, digital currency, commodity currency, etc. A first asset exchange may hold a first user's open order for purchase of the asset, while a second asset exchange may hold a second user's open order for sale of the asset. Unless the two asset exchanges coordinate with each other, both orders are at risk of not being executed. Such liquidity problems may be resolved by matching orders across multiple asset exchanges. In order to facilitate inter-exchange matching, a consolidated order book may be used. The consolidated order book may aggregate open orders resting on multiple asset exchanges. By allowing inter-exchange matching, liquidity of an asset may be increased. In examples, this may allow users to execute transactions between cryptocurrency and other currency, e.g., Bitcoin to U.S. dollars or vice versa. Additionally, the present systems and methods may enable transactions between different cryptocurrencies, e.g., Bitcoin to Ethereum or vice versa.
Furthermore, the consolidated order book may be updated as orders are added to, removed from, or modified in the order books of the particular asset exchanges. Therefore, the consolidated order book may be an accurate, real-time representation of order books for multiple asset exchanges. This may facilitate fast and accurate matching of orders across multiple asset exchanges.
Furthermore, each asset exchange facilitating an order execution may charge one or both counterparties a transaction fee. Many smaller transactions across asset exchanges can increase transactional costs. Accordingly, it may be beneficial to consolidate orders before execution. In such a custodial/escrow system, orders may be consolidated once they are matched, then executed periodically. Order(s) may then be executed periodically using custodial funds held on behalf of the user(s). A custodial/escrow system may reduce the total transactions performed and, therefore, reduce the amount of fees incurred. In contrast, a non-custodial system may place and execute each individual order, which may result in greater transaction costs.
In examples, the present systems and methods may be used with cryptocurrency exchanges. Using the custodial/escrow model, new orders may be consolidated together before they are executed and recorded on a blockchain. In contrast, a non-custodial model may execute each individual order and record it on the blockchain. Therefore, the non-custodial model would result in higher total transaction costs (e.g., fees charged by exchanges) than the custodial model of the present systems and methods.

As used herein, the term “asset exchange” refers to a marketplace (and/or a business entity that operates the marketplace) in which securities, commodities, derivatives and/or other financial instruments are traded. In examples, the asset exchanges described herein may serve as a marketplace for cryptocurrency, digital currency, fiat currency, and/or commodity currency. In examples, the one or more of the asset exchanges described herein may record successfully executed transactions on a distributed ledger, e.g., a blockchain. Alternatively, or in addition to, the asset exchanges may be configured to trade at least one security, at least one bond, at least one commodity, at least one piece of real property, at least one item of personal property, at least one fund, at least one currency fund, at least one exchange traded fund, at least one mutual fund, at least one index fund, at least one bond fund, at least one commodity fund, or at least one real estate fund. Each exchange computing device 108 herein may correspond to, and/or be operated by, a particular asset exchange. Accordingly, the terms “asset exchange” and “exchange computing device 108” may be used interchangeably.
As used herein, the term “order” refers to a request to initiate a transaction or data that describes a request to initiate a transaction. An order may be a request to trade any type of asset, including but not limited to, securities, bonds, currencies, real property, personal property, goods, funds and/or other assets. In examples, an order may be at least one of a buy, sell, and/or hold order. In examples, an order may include public addresses for accounts participating in the trade (such as a transmitting account and/or a target account), an indication of the asset being traded, and/or the quantity of the asset being traded. The order may also indicate optional attributes, such a limit price, stop price, conditional triggering requirements, duration of the order, whether the order may be partially filled, etc. In examples, the at least one optional input device and the at least one optional display device may be used by a user to create the order. In examples (such as where market timing is important to the user), each order can be sent immediately from a customer computing device 104 to the consolidated order book computing device 102 or an asset exchange. Alternatively, a user may enter an order directly on the consolidated order book computing device 102 or an asset exchange.
As used herein, the term “order book” refers to a collection of orders. The order book may be stored in a memory, e.g., one or more disk drives, flash drives, one or more databases, one or more tables, one or more files, local cache memories, processor cache memories, relational databases, flat databases, and/or the like.
As used herein, unless otherwise specified, the term “user of the system” (or simply “user”) refers to a person (or automated instructions, e.g., a script) that accesses, either directly or indirectly, the consolidated order book computing device 102, a customer computing device 104, and/or an exchange computing devices 108 to create, cancel, or modify an order.
The at least one processor 204 of the consolidated order book computing device 102 may be configured to generate, use and/or update a consolidated order book. The consolidated order book may be generated and updated based on information regarding a plurality of order books (e.g., residing on a plurality of exchange computing devices 108) and local orders received from users of the system 100. In examples, the consolidated order book may be implemented in the consolidated order book module 208.
The at least one processor 204 may also be configured to receive a new order from a user of the system 100, e.g., based on user input and/or automated instructions. Upon receiving a new order from an asset exchange, the at least one processor 204 may first determine whether the new order matches any orders in the consolidated order book. In examples, the matching may be implemented in the consolidated order book module 208.
The at least one processor 204 may determine whether the new order matches any orders in the consolidated order book in any suitable manner, e.g., complete matches, aggregated partial matches, etc. In examples, the at least one processor 204 may determine whether the new order partially matches a plurality of orders in the consolidated order book that correspond to a plurality of orders on at least one particular order book of at least one particular asset exchange. If so, and if execution of the plurality of partially-matched orders would effectively result in a complete match, the at least one processor 204 may consider the plurality of partial matches to be a match. In such a case, the at least one processor 204 may communicate a plurality of custodial orders to the at least one particular asset exchange to attempt to match a plurality of portions of the new order with a plurality of orders on the at least one particular order book of the at least one particular asset exchange. A plurality of transactions for the plurality of custodial orders and the plurality of orders on the at least one particular order book may be executed. If the plurality of custodial orders are matched and executed by the particular asset exchange, the at least one processor 204 may remove the new order from the consolidated order book corresponding to the plurality of orders on the at least one particular order book. However, when only a subset of the plurality of custodial orders are matched and executed, the at least one processor 204 may adjust the new order based on the subset of the plurality of custodial orders that are matched and executed. The portion of the new order remaining, after the subset of the plurality of custodial order are matched and executed, may be stored in the consolidated order book, local order book, or an order book on one of the asset exchanges.
In some cases, there may be multiple ways to match the new order to existing order(s) in the consolidated order book. In examples, a new order may match a single order in the consolidated order book as well as partially match a plurality of orders in the consolidated order book (that correspond to a plurality of orders on at least one particular order book of at least one particular asset exchange). If execution of the plurality of partially-matched orders would effectively result in a complete match, the at least one processor 204 may select the plurality of partially-matching orders (instead of the matching single order) in the consolidated order book for execution. In such a case, the at least one processor 204 may communicate a plurality of custodial orders to the at least one particular asset exchange to attempt to match a plurality of portions of the new order with a plurality of orders on the at least one particular order book of the at least one particular asset exchange and execute a plurality of transactions for the plurality of custodial orders and the plurality of orders on the at least one particular order book. Alternatively, the at least one processor 204 may select the matching single order for execution.
When the new order does not match any order in the consolidated order book, the at least one processor 204 may place the new order in the consolidated order book, a separate local order book on the consolidated order book computing device 102, or at least one of the order books of an asset exchange. In examples, the local order book may be implemented in the local order book module 212.
In examples, the consolidated order book computing device 102 may use a separate local order book to store local orders received from users of the system 100 that do not match to any order on the consolidated order book. In such a case, when the new order is received from a user of the system 100, the at least one processor 204 may place the new order in the separate local order book when the new order does not match any order in the consolidated order book.
In other examples, the consolidated order book computing device 102 may use a chosen order book on a chosen asset exchange to store new orders received from users of the system 100 that do not match to any order on the consolidated order book. In this example, when the new order is received from a user of the system 100, the at least one processor 204 may place the new order in the chosen order book of a chosen asset exchange when the new order does not match any order in the consolidated order book.
In other examples, the consolidated order book computing device 102 may use the consolidated order book to store new orders received from users of the system 100 that do not match to any order on the consolidated order book. In this example, when the new order is received from a user of the system 100, the at least one processor 204 may place the new order in the consolidated order book when the new order does not match any order in the consolidated order book.
When a new order (e.g., received at the consolidated order book computing device 102 from a user of the system 100) matches an order in the consolidated order book that corresponds to a particular order on a particular order book of a particular asset exchange, the at least one processor 204 may communicate a custodial order to the particular asset exchange to attempt to match the new order on the particular asset exchange using custodial assets for the user of the system 100. The custodial assets of the system 100 may be stored in an escrow account shared by many users. Therefore, the at least one processor 204 may also be configured to track individual assets, within the custodial assets, for the plurality of users.
When the custodial order matches the particular order on the particular asset exchange and a transaction of the custodial order and the particular order on the particular asset exchange is executed using the custodial assets for the user of the system, the at least one processor 204 may remove the new order from the consolidated order book corresponding to the particular order on the particular asset exchange. This removal may occur through an update of the consolidated order book based on information regarding the order books for the asset exchanges, including the particular order book of the particular asset exchange. The particular order book of the particular asset exchange may also be updated to reflect the matching of the custodial order. In other words, if the custodial order (e.g., sent following successful matching at the custodial order book computing device 102) is successfully matched again at the particular asset exchange, the consolidated order book and the particular order book of the particular asset exchange may both be updated to reflect the subsequent matching and/or execution.
In examples, the consolidated order book computing device 102 may match a particular order on the particular asset exchange, but the resulting custodial order does not match the particular order on the particular asset exchange and the transaction of the custodial order and the particular order on the particular asset exchange is not executed. This subsequent custodial order mismatch (following successful match to the consolidated order book) may occur because the consolidated order book had not yet been updated to show that the matching order had already been removed from the particular order book of the particular asset exchange. Alternatively, or in addition to, the subsequent custodial mismatch may occur because the matching order was removed from the particular order book of the particular asset exchange after it was matched to the new order in the consolidated order book, but before the custodial order matched to the particular order on the particular asset exchange and the transaction of the custodial order and the particular order on the particular asset exchange is executed. In either case, the at least one processor 204 may place the new order in the consolidated order book, the separate local order book on the consolidated order book computing device 102, or at least one of the order books of the plurality of asset exchanges.
In addition to new orders, the at least one processor 204 of the consolidated order book computing device 102 may also be configured to receive information regarding cancelation and/or modification of orders in one or more order books on the exchange computing devices 108. In other words, the at least one processor 204 may be configured to track any resting orders on the plurality of order books on the exchange computing devices 108 and any local resting orders resulting from local orders received from users of the system, i.e., a local order book may be separate from the consolidated order book, but also reside on the consolidated order book computing device 102. In examples, the exchange computing devices 108 may notify the consolidated order book computing device 102 when an order on the exchange order book is created, canceled, and/or modified. Alternatively, the consolidated order book computing device 102 may periodically request, from the exchange computing devices 108, information describing exchange order books.
The at least one processor 304 of the customer computing device 104 may be configured to create orders for the system 100, e.g., based on user input and/or automated instructions. In examples, the order creation may be implemented in the order creation module 308. The order(s) created by the user may relate to cryptocurrency, digital currency, fiat currency, securities, bonds, commodities, real property, personal property, a fund, a currency fund, an exchange traded fund, a mutual fund, an index fund, a bond fund, a commodity fund, and/or a real estate fund. The order(s) created by the user may include public addresses for accounts participating in the trade (such as a transmitting account and/or a target account), an indication of the asset being traded, and/or the quantity of the asset being traded. The order(s) may also indicate optional attributes, such a limit price, stop price, conditional triggering requirements, duration of the order, whether the order may be partially filled, etc. In examples, the at least one optional input device 316 and the at least one optional display device 314 are used by a user to create the order. The at least one processor 304 may also be configured to send the new order to one of the exchange computing devices 108 and, optionally, send the new order to the consolidated order book computing device 102.
The at least one processor 304 may also be configured to modify or cancel the order, e.g., based on further user input and/or automated instructions. Order modification may be implemented in the order modification module 310. Various parameters of an order may be modified without canceling the order, e.g., limit price, a quantity of the asset being traded, whether the user is willing to accept partial fill of the order, duration of the order, etc. When an order is modified or canceled, the at least one processor 304 may also be configured to send a notification of the order modification to one of the exchange computing devices 108 and, optionally, send the consolidated order book computing device 102.
The exchange computing device 108 may correspond to an asset exchange. The asset exchange may serve as a marketplace for orders created by the user for transactions involving cryptocurrency, digital currency, fiat currency, securities, bonds, commodities, real property, personal property, funds, currency funds, exchange traded funds, mutual funds, index funds, bond funds, commodity funds, and/or real estate funds. In examples, the one or more of the asset exchange described herein may record successfully executed transactions (e.g., cryptocurrency transactions) on a distributed ledger, e.g., a blockchain.
The at least one processor 404 of the exchange computing device 108 may be configured to receive a new order. Upon receiving the new order, the at least one processor 404 may update an exchange order book based on the new order. In examples, the exchange order book may be implemented in the exchange order book module 408. The exchange order book may be a collection of orders awaiting execution on the particular asset exchange. The new order may be received from a user of the particular asset exchange (either directly on the exchange computing device 108 or via a customer computing device 104) or received from the consolidated order book computing device 102. Additionally, the at least one processor 404 may also be configured to send a notification of changes (e.g., creation, modification, cancellation of orders) to the exchange order book to the consolidated order book computing device 102 to update the consolidated order book.
The at least one processor 404 may also be configured to receive a custodial order from a consolidated order book computing device 102. The custodial order may be based on a notification of changes sent from the asset exchange to the consolidated order book computing device 102. Alternatively, the custodial order may be generated at the consolidated order book computing device 102 based on a notification or order that the consolidated order book computing device 102 receives from a different asset exchange.
Upon receiving the custodial order, the at least one processor 404 may determine whether the custodial order matches any orders in the exchange order book. In examples, the matching may be implemented in the exchange matching module 410. In examples, the at least one processor 404 may be configured to match one or more custodial orders (received from the consolidated order book computing device 102) with one or more particular orders in the exchange order book. The matching may include matching a plurality of single custodial order to a single order in the exchange order book, a single custodial order to multiple orders in the exchange order book, multiple custodial orders to a single order in the exchange order book, and/or multiple custodial orders to multiple orders in the exchange order book.
When the at least one processor 404 is able to match the one or more custodial orders with one or more particular orders in the exchange order book, the at least one processor 404 may execute a transaction with the custodial order(s) and the particular order(s) in the exchange order book. In examples, execution of trades may be implemented in the execution module 412. When the custodial order(s) match particular order(s) in the exchange order book, the at least one processor 404 may be configured to record the executed transaction using a distributed ledger during execution of the transaction, e.g., on a blockchain.
Additionally, the exchange order book may be used as a resting place for new orders, received at the consolidated order book computing device 102, that do not match any orders in the consolidated order book. In examples, the at least one processor 404 may optionally be configured to receive, from a consolidated order book computing device 102, a new order that corresponds to a custodial order that was not matched by the asset exchange. The at least one processor 404 may also optionally be configured to place the new order, which corresponds to the custodial order that was not matched by the asset exchange, into the exchange order book.
The at least one processor 204 may also be configured to receive 508 a new order from a user of the system 100, e.g., based on user input and/or automated instructions. Upon receiving the new order, the at least one processor 204 may determine 510 whether the new order matches any orders in the consolidated order book. The consolidated order book may include orders resting on a plurality of order books of a plurality of asset exchanges and local orders received from users of the system 100. The at least one processor 204 may determine whether the new order matches any orders in the consolidated order book by looking for complete matches and/or aggregated partial matches.
When the new order does not match any order in the consolidated order book, the at least one processor 204 may place 512 the new order in the consolidated order book, a separate local order book on the consolidated order book computing device 102, or at least one of the order books in an asset exchange. In examples, the consolidated order book computing device 102 may use a separate local order book to store local orders received from users of the system 100 that do not match to any order on the consolidated order book. In this example, when the new order is received from a user of the system 100, the at least one processor 204 may place the new order in the separate local order book when the new order does not match any order in the consolidated order book. In other examples, the consolidated order book computing device 102 may use a chosen order book on a chosen asset exchange to store new orders received from users of the system 100 that do not match to any order on the consolidated order book. In this example, when the new order is received from a user of the system 100, the at least one processor 204 may place the new order in the chosen order book of a chosen asset exchange when the new order does not match any order in the consolidated order book. In other examples, the consolidated order book computing device 102 may use the consolidated order book to store new orders received from users of the system 100 that do not match to any order on the consolidated order book. In this example, when the new order is received from a user of the system 100, the at least one processor 204 may place the new order in the consolidated order book when the new order does not match any order in the consolidated order book.
When the new order (e.g., received at the consolidated order book computing device 102 from a user of the system 100) matches an order in the consolidated order book that corresponds to a particular order on a particular order book of a particular asset exchange, the at least one processor 204 may communicate 514 one or more custodial orders to the particular asset exchange to attempt to match the new order on the particular asset exchange using custodial assets for the user of the system.
After the custodial order is sent to the particular asset exchange, the at least one processor 204 may continue to monitor for confirmation or failure notifications relating to the custodial order. In examples, the at least one processor 204 may determine 516 whether the particular asset exchange matched the custodial order to the particular order on the particular asset exchange and whether a transaction of the custodial order and the particular order on the particular asset exchange was executed. When the particular asset exchange matches the custodial order to the particular order and a transaction of the custodial order and the particular order on the particular asset exchange is executed using the custodial assets for the user of the system, the at least one processor 204 may remove 518 the new order from the consolidated order book corresponding to the particular order on the particular asset exchange. This removal may occur through an update of the consolidated order book based on information regarding the order books for the asset exchanges, including the particular order book of the particular asset exchange. The particular order book of the particular asset exchange may also be updated to reflect the matching of the custodial order.
However, if the asset exchange does not match the custodial order to a particular order or and/or the transaction of the custodial order and the particular order on the particular asset exchange is not executed, the at least one processor 204 may place 512 the new order in at least one of the consolidated order book, the separate local order book on the consolidated order book computing device 102, or at least one of the order books of an asset exchange. The custodial order mismatch at the asset exchange (following successful match to the consolidated order book at the consolidated order book computing device 102) may occur because the consolidated order book had not yet been updated to show that the matching order had already been removed from the particular order book of the particular asset exchange. Alternatively, or additionally, the custodial mismatch may occur because the matched order was removed from the particular order book of the particular asset exchange after it was matched to the new order in the consolidated order book, but before the custodial order could be matched with the particular order on the particular asset exchange and the transaction of the custodial order and the particular order on the particular asset exchange could be executed.
The at least one processor 304 may optionally also be configured to modify or cancel 608 the order, e.g., based on further user input and/or automated instructions. Various parameters of an order may be modified without canceling the order, e.g., limit price, stop price a quantity of the asset being traded, whether the user is willing to accept partial fill of the order, duration of the order, etc. When an order is modified or canceled, the at least one processor 304 may also be configured to send 610 a notification of the order modification to one of the asset exchanges and, optionally, send 612 a notification to the consolidated order book computing device 102.
The at least one processor 404 may also be configured to receive 708 a custodial order from a consolidated order book computing device 102. The custodial order may be based on the notification of changes sent to the consolidated order book computing device 102. Alternatively, the custodial order may be generated at the consolidated order book computing device 102 based on a notification or order it receives from a different asset exchange. Upon receiving the custodial order, the at least one processor 404 may determine 710 whether the custodial order matches any orders in the exchange order book. The matching may include matching a plurality of single custodial order to a single order in the exchange order book, a single custodial order to multiple orders in the exchange order book, multiple custodial orders to a single order in the exchange order book, and/or multiple custodial orders to multiple orders in the exchange order book.
When the at least one processor 404 is able to match the custodial order with a particular order in the exchange order book, the at least one processor 404 may execute 712 a transaction with the custodial order and the particular order in the exchange order book. If the custodial order matches with a particular order in the exchange order book, the at least one processor 404 may send 714 a notification (e.g., to the consolidated order book computing device 102 and, optionally, a customer computing device 104) of the transaction with the custodial order and the particular order in the exchange order book. When the custodial order matches a particular order in the exchange order book, the at least one processor 404 may record 716 the executed transaction using a distributed ledger during execution of the transaction, e.g., on a blockchain.
However, if the custodial order does not match any orders in the exchange order book, the at least one processor 404 may send 718 a notification, to the consolidated order book computing device 102, indicating a failure to match the custodial order with any orders in the exchange order book. The at least one processor 404 may optionally receive 720, from a consolidated order book computing device 102, a new order that corresponds to a custodial order that was not matched by the asset exchange. The at least one processor 404 may also optionally place 722 the new order, which corresponds to the custodial order that was not matched by the asset exchange, into the exchange order book.
