Description

Technical Field

[0001] The present disclosure relates to the technical field of order storage of financial trading systems such as securities and stocks, and in particular to a DPU-based order method, device, electronic equipment, and medium. Background Art

[0002] High-frequency trading in the financial trading field is an important application field of ultra-low latency, and it is also the field that pursues the most extreme performance. Financial institutions and exchanges need to trade at the level of subtle or even nanoseconds to gain market advantages. Therefore, it is crucial for trading platforms and network infrastructure to achieve ultra-low latency. In the field of high-frequency trading, with the popularization of ultra-low latency technology of DPU (Data Processing Unit), the development of ultra-low latency and high-speed trading systems based on DPU has become a consensus among financial institutions.

[0003] In the related technology, based on the low-latency network card / DPU acceleration card, the UDP data packet that conforms to the exchange order format is sent to the low-latency network card through the software protocol stack, and then the low-latency network card sends the data to the trading network, and finally transmits it to the exchange. When the trading strategy triggers the order, it is necessary to send a UDP (User Datagram Protocol) data packet in accordance with the protocol data format of the exchange. However, the existing solutions all start sending from the first byte of the UDP data packet at the moment the order data is received. This method will cause transmission delays in the order link. Therefore, in the trading scenario, how to send the trading order to the exchange faster is an urgent problem to be solved. Summary of the invention

[0050] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs.

[0053] Glossary:

[0054] High-frequency trading (HFT) is an automated trading method that uses high-speed computer algorithms and network technology to conduct a large number of transactions in a very short period of time. This trading strategy relies on small market changes, such as small fluctuations in stock prices or price differences between different exchanges, to achieve profits. Characteristics of high-frequency trading include fast execution of trading orders, low-latency trading systems, and rapid response to market data. High-frequency trading (HFT) systems may use automated algorithms to quickly generate and execute trade orders to take advantage of small market fluctuations to profit.

[0055] DPU is a processor designed specifically for data centers to efficiently handle large-scale data workloads, including data transmission, protocol, protection, compression, analysis and encryption. Compared with traditional CPUs and GPUs, DPU focuses on data-centric workloads such as network, storage and security operations in data centers.

[0056] UDP is a connectionless network protocol used to transmit data in IP networks. It belongs to the transport layer protocol and is parallel to TCP (Transmission Control Protocol), but the main difference from the TCP protocol is that UDP is stateless and does not guarantee the order, integrity and reliability of data packets. UDP provides a simple way to send encapsulated IP data packets, but does not sort the data or ensure that they reach their destination.

[0057] Trading orders usually refer to instructions issued by investors or traders in the financial market to buy or sell securities, stocks, futures, foreign exchange and other financial products. These instructions contain detailed information about the transaction, such as the financial product code, transaction direction (buy or sell), transaction quantity, price, etc. The execution of trading orders is usually carried out through the trading system of the exchange, which determines the execution method of the order based on the type and duration of the order.

[0058] The basic types of trading orders include: market order, limit order, stop loss order, take profit order, iceberg order and other types. Among them, market order refers to an instruction to buy or sell immediately at the current market price. Limit order means setting a specific price, and the buy or sell will be executed only when the market price reaches or exceeds this price. Stop loss order means that when the market price reaches a certain level, the stop loss order will be triggered, usually used to limit losses. Take profit order is similar to stop loss order, but is used to lock in profits and is triggered when the price reaches a preset level. Iceberg order refers to a large transaction order, only a small part of the transaction volume is displayed, and the rest is hidden to avoid excessive impact on the market price.

[0059] Trading strategies refer to a set of rules and methods developed in order to achieve profit goals in the financial market. Different traders adopt different trading strategies based on their risk preferences, market analysis, money management capabilities and other factors.

[0060] RAM (Random Access Memory) is hardware used in computers and other electronic devices to temporarily store data and programs. It is the computer's primary memory, used to store data and instructions currently in use while the computer is running. RAM is usually volatile, meaning that when the power is turned off, the data stored in RAM is lost. RAM allows data to be read and written quickly, which allows computers to quickly access and process information.

[0061] In the related technology, based on the low-latency network card / DPU acceleration card, the UDP data packet that conforms to the exchange order format is sent to the low-latency network card through the software protocol stack, and then the low-latency network card sends the data to the trading network, and finally transmits it to the exchange. When the trading strategy triggers the order, it is necessary to send a UDP (User Datagram Protocol) data packet in accordance with the protocol data format of the exchange. However, the existing solutions all start sending from the first byte of the UDP data packet at the moment the order data is received. This method will cause transmission delays in the order link. Therefore, in the trading scenario, how to send the trading order to the exchange faster is an urgent problem to be solved.

[0062] In order to solve the above problems, the present disclosure proposes a DPU-based order method. When receiving static data sent based on a preset order protocol, the static data is sent to the trading network port in advance, and the order data is sent to the trading network port according to the timing of receiving the order data. Since the static data is used to represent the header information of the current transaction order, and the order data is the business data transmitted for each transaction order, by sending the header information of the current transaction order to the trading network port in advance, and then sending the order data according to the timing of receiving the order data, from receiving the order data to completely sending the entire transaction order, the delay of the order link can be reduced, and extremely fast order can be achieved.

[0063] Reference Figure 1 As shown, Figure 1 The flowchart of the order placing method based on DPU is shown in FIG. 1 , and the method includes the following steps S11-S12:

[0064] S11. When receiving static data sent based on a preset order protocol, the static data is sent to the transaction network port in advance.

[0065] Wherein, the static data is used to represent the header information of the current transaction order. The static data includes: Ethernet frame header data, IP header data, the preset order protocol header data and message header data. Wherein, the Ethernet frame header data includes: Ethernet type, source MAC address, destination MAC address. The IP header data includes: IP protocol version, IP header length, service type, total length, identifier, source IP address, destination IP address, etc. The UDP header data includes: source port, destination port, length, checksum, etc. The message header part is used to distinguish different types of message information, such as stop loss order, take profit order, iceberg order and other types.

[0066] The preset order reporting protocol may be, but is not limited to, UDP protocol, TCP protocol, etc. In the embodiment of the present disclosure, the UDP protocol is taken as an example to illustrate the order reporting method based on UDP.

[0067] Specifically, when the low-latency network card / DPU accelerator card receives static data sent based on the UDP protocol, the static data is sent to the trading network port in advance. When using the UDP protocol for data transmission, the data packet will be encapsulated in the Ethernet frame (Ethernet Frame), IP (Internet Protocol) header and UDP header in turn. The header information of the current transaction order includes source MAC, destination MAC, source port, destination port, message format, message length and other contents. Since the header information of the current transaction order does not change with the specific transaction order, it can be pre-configured and issued in the form of initialization parameters in the initialization module.

[0068] For example, refer to Figure 2a As shown in the figure, a typical UDP order structure includes: Frame Header, IP Header, UDP Header, UDP data (PayloadHeader+Payload data). UDP order refers to trading instructions or quotation information transmitted using the UDP protocol. In this case, the order structure is defined at the application level, not the UDP protocol itself. The payload data part usually consists of a message header and a message content field. The message header is used to distinguish different types of message information and has nothing to do with the specific order transaction content. It can be pre-configured and issued in the initialization module in the form of initialization parameters; the message content field is the data field actually transmitted for each transaction order.

[0069] Assuming that the transaction order is sent through a 10Gbs network port and the main frequency of the business logic is 322MHz, 32 bits, or 4 bytes of data, can be sent per clock cycle. Assuming that the payload part contains 64 bytes (i.e. 16 clock cycles), of which the message header part is 16 bytes (i.e. 4 clock cycles) and the message content is 48 bytes (i.e. 12 clock cycles). The Frame Header, IPHeader and UDP Header parts are 42 bytes (i.e. 11 clock cycles). According to the traditional hardware order method, starting from the receipt of the order data, it is sent in the format of a UDP packet, which requires a total of 27 clock cycles (11 clock cycles for header information + 16 clock cycles for payload data), about 83ns, such as Figure 2a shown.

[0070] The data transmitted in the first 15 clock cycles does not depend on the specific transaction content, and only the last 48 bytes of the message content are related to the transaction content (i.e., the received order data part). Therefore, the information Frame Header, IP Header, UDP Header, and Payload Header of the UDP packet header can be collectively referred to as static data, which can be sent to the RAM (Random Access Memory) on the accelerator card in a pre-configured manner for caching.

[0071] S12. Send the order data to the transaction network port according to the timing of receiving the order data.

[0072] The order data is the business data transmitted for each transaction order. The order data is used to describe the detailed information of the transaction, including, for example, the financial product code of the transaction, the transaction direction, the transaction quantity, the price, the time when the order was generated, the order ID, the validity period of the order, etc.

[0073] Specifically, when the order data is not received, the header information is sent to the network port in advance, and the following situations are classified according to the situation of receiving the order data.

[0074] In some embodiments, the above step S12 (sending the order data to the trading network port according to the timing of receiving the order data) can be implemented as follows:

[0075] If the order data is received during the last clock cycle of sending the static data, the order data will be sent to the transaction network port starting from the next clock cycle.

[0076] Specifically, the order data is received in the last clock cycle of sending the static data, and the Payload Data data is sent from the next clock cycle.

[0077] For example, refer to Figure 2b As shown, in this scenario, from receiving the order data to sending the message completely, only 12 clock cycles are needed, which saves 15 clock cycles compared with the traditional method.

[0078] In some embodiments, the above step S12 (sending the order data to the trading network port according to the timing of receiving the order data) can also be implemented in the following way:

[0079] If the order data is received during the process of sending the static data, the order data is cached in a first-in-first-out queue;

[0080] When the static data is sent completely, the order data is sent to the transaction network port.

[0081] Specifically, if Payload Data is received during the process of sending static data, Payload Data is cached in a first-in-first-out queue FIFO, and Payload Data continues to be sent after the static data is sent.

[0082] For example, refer to Figure 2c As shown, assuming that the static data is sent 4 clock cycles before the order data is received, it only takes 23 clock cycles from receiving the order data to the complete sending of the message, which saves 4 clock cycles compared to the traditional method.

[0083] In some embodiments, the above step S12 (sending the order data to the trading network port according to the timing of receiving the order data) can also be implemented in the following way:

[0084] If the static data has been sent and the order data has not been received, the static data is discarded.

[0085] Specifically, if the static data has been sent and the order data has not been received, the sending will be terminated immediately. The sent data packet will be identified as an incomplete data packet in the transmission link and discarded due to the length error (i.e., the 48 bytes of data of PayloadData are missing).

[0086] Further, in some embodiments, after executing the above steps (if the static data has been sent and the order data has not been received, the static data is discarded), the following steps may also be executed:

[0087] Starting from the next clock cycle, the static data is pre-sent cyclically until the order data is received, and then the order data is sent to the transaction network port.

[0088] Specifically, if the order data has not been received in the last clock cycle of the first pre-sending, the sending of the current data packet is terminated; and the second pre-sending is cyclically performed from the next clock cycle until the order data is received.

[0089] For example, refer to Figure 2d As shown, if the order data is not received in the last clock cycle of the first pre-sending, the first sending of static data is terminated. The second pre-sending of static data is cyclically performed from the next clock cycle until the order data is received and the order data is sent to the trading network port.

[0090] Optionally, the above step (starting from the next clock cycle, cyclically pre-sending the static data until the order data is received, and then sending the order data to the transaction network port) can be implemented in the following two ways:

[0091] Mode 1: Starting from the next clock cycle, the static data is pre-sent cyclically, and when the number of times the static data is sent is greater than a preset number, the pre-sending operation of the static data is stopped.

[0092] Among them, the preset number of times can be set according to the actual application scenario. For example, the preset number of times can be 5 times, 10 times, etc., or other reasonable values, and no specific restrictions are made here.

[0093] Specifically, if the order data is not received in the last clock cycle of the first pre-sending, the first sending of static data is terminated. The second pre-sending of static data is cyclically performed from the next clock cycle. When the number of sending of static data is greater than the preset number, the pre-sending operation of static data is stopped, and the whole process ends.

[0094] For example, assuming that the preset number of times is 5 times, if the order data is not received in the last clock cycle of the first pre-sending, the first sending of static data is terminated. The second pre-sending of static data is cyclically performed from the next clock cycle. When the number of sending of static data is greater than 5 times, the pre-sending operation of static data is stopped, and the whole process ends.

[0095] Mode 2: Starting from the next clock cycle, the static data is pre-sent cyclically, and when the order data is not received within a preset time, the pre-sending operation of the static data is stopped.

[0096] Among them, the preset time can be set according to the actual application scenario. For example, the preset time can be 10 milliseconds, 20 milliseconds, 50 milliseconds, etc., or other reasonable values, and no specific restrictions are made here.

[0097] Specifically, if the order data is not received in the last clock cycle of the first pre-sending, the first sending of static data is terminated. The second pre-sending of static data is cyclically performed from the next clock cycle. If the order data is not received within the preset time, the pre-sending operation of static data is stopped, and the whole process ends.

[0098] For example, assuming that the preset time is 20 milliseconds, if the order data is not received in the last clock cycle of the first pre-sending, the first sending of static data is terminated. The second pre-sending of static data is performed cyclically from the next clock cycle. When the order data is not received within 20 milliseconds, the pre-sending operation of static data is stopped, and the whole process ends.

[0099] The embodiment of the present disclosure should be used. The DPU-based order method provided by the present disclosure, when receiving static data sent based on a preset order protocol, sends the static data to the transaction network port in advance, and sends the order data to the transaction network port according to the timing of receiving the order data. Since the static data is used to represent the header information of the current transaction order, and the order data is the business data transmitted for each transaction order, by sending the header information of the current transaction order to the transaction network port in advance, and then sending the order data according to the timing of receiving the order data, from receiving the order data to completely sending the entire transaction order, the delay of the order link can be reduced, and extremely fast order can be achieved.

[0103] As an optional implementation of the embodiment of the present disclosure, the decision module is specifically used to:

[0104] If the order data is received during the last clock cycle of sending the static data, the order data will be sent to the transaction network port starting from the next clock cycle.

[0105] As an optional implementation of the embodiment of the present disclosure, the decision module is further specifically used for:

[0106] If the order data is received during the process of sending the static data, the order data is cached in a first-in-first-out queue;

[0107] When the static data is sent completely, the order data is sent to the transaction network port.

[0108] As an optional implementation of the embodiment of the present disclosure, the decision module is further specifically used for:

[0109] If the static data has been sent and the order data has not been received, the static data is discarded.

[0110] As an optional implementation of the embodiment of the present disclosure, the device further includes:

[0111] The circulation module is used to perform cyclic pre-sending of the static data starting from the next clock cycle until the order data is received, and then send the order data to the transaction network port.

[0112] As an optional implementation of the embodiment of the present disclosure, the circulation module is specifically used for:

[0113] Starting from the next clock cycle, the static data is pre-sent cyclically, and when the number of times the static data is sent is greater than a preset number, the pre-sending operation of the static data is stopped.

[0114] As an optional implementation of the embodiment of the present disclosure, the circulation module is further specifically used for:

[0115] Starting from the next clock cycle, the static data is pre-sent cyclically, and when the order data is not received within a preset time, the pre-sending operation of the static data is stopped.

[0116] By applying the embodiments of the present disclosure, the DPU-based order placing device provided by the present disclosure, when receiving static data sent based on a preset order placing protocol, sends the static data to the trading network port in advance, and sends the order data to the trading network port according to the timing of receiving the order data.
