[0025] It should be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0026] The following will be seen Figure 1 , Figure 1A flowchart of a method for cross-border joint processing of financial transaction orders according to an embodiment of the present application is shown in FIG. 1, which includes steps S101-S103.

[0027] S101, receiving a financial transaction order instruction sent by an overseas system through an adaptive order information collection algorithm in a cross-border joint order bus technology;

[0028] S102, performing message format conversion on the financial transaction order instruction using a dynamic configuration in the adaptive order information collection algorithm, so that the message format of the converted financial transaction order instruction matches that of a domestic system, and then sending the financial transaction order instruction to the domestic system;

[0029] S103, when the domestic system completes a corresponding financial transaction according to the financial transaction order instruction and returns a corresponding deal return, receiving the deal return sent by the domestic system, and returning the deal return to the overseas system through the cross-border joint order bus technology.

[0030] In this embodiment, the cross-border financial order is processed through the cross-border joint order bus technology based on the Fix protocol. First, the financial transaction order instruction sent by the overseas system is received through the adaptive order information collection algorithm in the cross-border joint order bus technology. Since there may be differences between the overseas system and the domestic system, the financial transaction order is converted in message format using the dynamic configuration in the adaptive order information collection algorithm, and then the financial transaction order instruction after the message format conversion is sent to the domestic system. The domestic system executes the corresponding financial transaction according to the financial transaction order instruction sent by the cross-border joint order bus technology, and returns the corresponding deal return after completing the corresponding financial transaction. The cross-border joint order bus technology receives the deal return and returns it to the overseas system through the cross-border joint order bus technology.

[0031] The method for cross-border joint processing of financial transaction orders provided by the embodiment can process financial transaction orders across systems and across borders, and the communication format (i.e., the message format) adopts the financial transaction Fix protocol, so that the transaction orders can be cross-border and cross-system in real time, safely and consistently, without the need to develop a special asset management interface system, thereby reducing the operational risk and saving additional expenses. It should be noted that the cross-border joint order bus technology described in the embodiment introduces real-time cross-border calculation parameter sets, cross-system user identification coding sets, cross-system portfolio account conversion codes, cross-system security identification coding sets, cross-system risk control decision opinion coding sets, and the like, and assembles the above cross-border order element sets according to a preset standard. At the same time, the financial transaction order instructions described in the embodiment can refer to order information (such as a direction of entrustment, a business type, and the like) of a domestic or overseas system, risk control decision information (such as risk control prohibition, risk control warning, risk control prompt, and the like), and user and account information (such as an account type, and the like), and the like. That is, when the message format of the financial transaction order is converted by using the dynamic configuration in the adaptive order information collection algorithm, the format of different types of information is dynamically converted into a format suitable for the cross-border joint order bus technology.

[0032] In addition, the method for cross-border joint processing of financial transaction orders provided by the embodiment effectively combines the respective advantages of the overseas system and the domestic system based on the investment transaction demand of the QDII fund Hong Kong Stock Connect business, proposes and implements a system solution for global integrated investment transactions, not only meets the investment needs of QDII, A shares (i.e., renminbi ordinary shares), and Hong Kong Stock Connect (i.e., Hong Kong Stock Connect under the Shanghai-Hong Kong Stock Connect), but also supports future investment businesses such as the Shanghai-London Stock Connect, thereby providing effective support for the company to carry out global investment businesses and becoming an important tool for domestic investors to carry out global investment. Moreover, since risk control is the criterion for investment business development, the cross-border and cross-market risk control problems involved in the QDII fund investment in Hong Kong Stock Connect have been hindering the development of related businesses. The method for cross-border joint processing of financial orders provided by the embodiment adopts a system cascade mode, and connects two-level risk control modules of the overseas system and the domestic system, thereby solving the fair trade, intraday reverse, and related party risk control problems of listed companies issuing A shares and H shares (also referred to as state-owned shares, i.e., stocks of Chinese enterprises registered in mainland China and listed in Hong Kong), and effectively avoiding business risks. At the same time, as A shares gradually become internationalized, the demand of overseas investors for A shares is increasingly strong, but the problem of insufficient investment tools and channels has gradually emerged. The method for cross-border joint processing of financial orders provided by the embodiment provides a new selection scheme for overseas investors to invest in A shares, and also enables overseas investors to obtain investment advisory services and transaction support services by placing orders to a fund company.

[0033] For example, the fund manager (asset management user) issues investment instructions through the overseas investment management system, and the cross-border asset instruction data is transferred to the order matching module of the domestic investment management system through the cross-border joint order bus technology at the time of transaction, and then the transaction return information returns to the overseas investment management system along the original path. The transaction execution of the cross-border instruction remains unchanged, thereby realizing the order circulation of the double-end system, and at the same time, the cross-border joint risk control is realized through the risk control modules of the two-end systems. In addition, the cross-border joint order bus technology is used to receive financial transaction order instructions sent by the overseas system. For example, in the process of receiving financial transaction order instructions, the order access device dynamically generated by the adaptive order generation technology communicates with the Bloomberg system, that is, the order access device dynamically generated by the adaptive order generation technology acts as the accepter (receiver), and the Bloomberg system acts as the initiator (initiator), and the connection is initiated by the Bloomberg system.

[0034] In an embodiment, the step 101 comprises:

[0035] The message format of the received financial transaction order instruction is converted into the message format of the Fix protocol by using the Quickfix technology.

[0036] In this embodiment, after receiving the financial transaction order instruction, in order to match the message format of the financial transaction order instruction with the message format of the cross-border joint order bus technology, the message format of the financial transaction order instruction is converted into the message format of the Fix protocol by using the Quickfix technology, that is, the message format of the financial transaction order instruction is converted into the Fix C++Object by using the Quickfix technology.

[0037] In an embodiment, the cross-border joint processing method of the financial transaction order further comprises:

[0038] The financial transaction order instruction is processed into a circular logic array by using a hash algorithm;

[0039] The lock-free atomic communication bus is assembled according to the circular logic array;

[0040] The logical pointers for the entry and exit of each circular logic array are set by using the CAS technology, and the access address for each space corresponding to each circular logic array is set;

[0041] The financial transaction order instruction after message format conversion is stored in the lock-free message queue.

[0042] In this embodiment, the physical linear memory space corresponding to the financial transaction order instruction is mapped to a logical ring logical array through hash operation, and a lock-free atomic communication bus is assembled according to the ring logical array. Meanwhile, the CAS (compare and swap) technology is used to set logical pointers for the entry and exit of each ring logical array, and access addresses are set for each space corresponding to each ring logical array, so as to solve the competition problem between financial transaction order instructions, improve the performance of cross-border joint order bus technology, and reduce resource consumption. CAS is a CPU concurrent primitive, which can judge whether the value of a certain memory position is the expected value, and update it to a new value if it is. The address of the financial transaction order instruction on the cross-border joint order bus is encoded. Compared with the conventional locking mode, the CAS operation consumes less resources and has a high performance advantage, and is very suitable for application in large-scale financial transaction order processing.

[0043] In addition, the embodiment realizes high concurrency of message processing under the premise of ensuring consistency through the design of memory-level ring logical array. Specifically, an array of 1024 continuous addresses is applied in the system memory, the array is formed into a ring through Hash operation on the address, the results of the transaction orders (i.e. the addresses to be written according to Hash operation) successively generated by the initiator are written in the corresponding positions in the ring in advance, and the arriving transaction orders can be independently written according to the processing progress of the threads they are online. Through the advance application of positions and the advance calculation of numbers, the massive order synchronization, rapid and orderly "check-in" of the bus is realized by "exchanging time for space", avoiding the huge overhead caused by frequent locking in the conventional queuing. In addition to the ring logical array, there are pointers indicating the head and tail of the queue, providing a high-concurrency and high-reliability producer order entry interface and a consumer order consumption interface. The embodiment can also meet the access of multiple initiator nodes and the generation of orders at the same time, and the access of multiple accepter nodes and the processing of orders at the same time, effectively realizing the rapid multiplication of business.

[0044] In an embodiment, assembling the lock-free atomic communication bus according to the ring logical array comprises:

[0045] Obtaining the number of bytes in the lock-free message queue, and determining whether the number of bytes reaches a preset number of bytes;

[0046] If the number of bytes in the lock-free message queue does not reach the preset number of bytes, the lock-free message queue is byte padded.

[0047] In this embodiment, the memory padding and cache alignment technology can greatly improve the cache efficiency and hit rate of the financial transaction order instruction, that is, the ring logic array is supplemented by the cache alignment technology. It can be understood that when the ring logic array is supplemented, the space in the ring logic array is actually supplemented, rather than directly supplementing the ring logic array. In addition, it should be noted that before the step of setting a logical pointer for the entry and exit of each ring logic array and setting an access address for each space corresponding to each ring logic array by using the CAS technology, byte padding is performed, that is, the ring logic array is supplemented by the cache alignment technology, and then the CAS technology is used to set a logical pointer for the entry and exit of each ring logic array.

[0048] In a specific application scenario, the memory padding and cache alignment technology can support processing 100 million messages per second. The cache memory, that is, the cache memory, reads the financial transaction order instruction from the cache memory much faster than from the memory. The cache memory caches data by row, and a cache line is generally 64 bytes. If the message length of the lock-free message queue is not enough for 64 bytes, other data will also enter the cache line at the same time, which will cause the cache line to be invalid, and thus the financial transaction order instruction needs to be read from the memory again, which will cause the performance of the cross-border joint order bus technology to decrease. Therefore, in order to ensure that each financial transaction order instruction in the lock-free message queue can occupy a cache line and avoid interference from other financial transaction order instructions, the lock-free message queue that is less than 64 bytes is padded to align with the cache line size.

[0049] In an embodiment, the step 102 comprises:

[0050] The storage address of the ring logic array is encrypted to obtain a first sub-key;

[0051] According to the message data of the financial transaction order instruction, the information space is divided and the memory is padded;

[0052] A triple data encryption algorithm is used as a base encryptor to encrypt the financial transaction order instruction by using a first sub-key mapped in sequence;

[0053] The encrypted financial transaction order instruction is decoded and deconstructed by using the protobuf coding technology, so that the message format of the financial transaction order instruction is compatible with the message format of the domestic system.

[0054] In this embodiment, a high-concurrency bus encryption algorithm is designed based on the CTR symmetric encryption idea. Specifically, the counter parameter of the CTR symmetric encryption is replaced by the storage address of the financial transaction order instruction processing as a ring logic array, a series of first-level sub-keys are directly encrypted by the storage address step by step, then the order message data is divided according to the design structure (regular encryption algorithm according to fixed length division) and filled in memory, and then a triple data encryption algorithm (Triple DES) is used as a base encryptor, and each part is encrypted by the first-level sub-key mapped in sequence instead of XOR operation. The reuse of the Hash virtual address in this embodiment realizes the adaptive order information collection algorithm and the credential connection of the lock-free atomic communication bus. Both the receiving and transmitting ends can efficiently encrypt and decrypt according to the limited virtual address information, and the intercepted person cannot obtain the order information, which perfectly realizes the order communication security. In addition, in the message division encryption process, the plaintext, ciphertext and key of the front and rear parts are not dependent on any calculation, which perfectly supports high-performance parallel computing and guarantees the order throughput rate of the bus. Further, the encrypted financial transaction order instruction is decoded and data is deconstructed by using the protobuf coding technology, so that the message format of the financial transaction order instruction is compatible with the message format of the domestic system, so that the domestic system can receive the financial transaction order instruction without obstacles.

[0055] In an embodiment, before the step 102, the step 102 comprises:

[0056] The field validity check and the business validity check are performed on the financial transaction order instruction.

[0057] When the fields in the financial transaction order instruction are valid and the business is valid, the message format conversion step is entered.

[0058] In the embodiment, before the dynamic configuration in the adaptive order information collection algorithm converts the message format of the financial transaction order instruction, the received financial transaction order instruction is checked, such as checking the field validity and business validity in the financial transaction order instruction, and only when the field in the financial transaction order instruction is valid and the business is also valid, the dynamic configuration in the adaptive order information collection algorithm converts the message format of the financial transaction order instruction. That is, if the field of the financial transaction order instruction is invalid, or the business is invalid, or the field and the business are invalid, the financial transaction order instruction is not converted in message format, so the financial transaction order instruction cannot be processed continuously. For example, the validity of the direction field in a financial transaction order instruction is checked. Specifically, for a stock buying and selling financial transaction order instruction, it is checked whether the direction field in the stock buying and selling financial transaction order instruction is buy or sell. If the direction field is buy or sell, the message format conversion step is entered. If the direction field is other values, it is determined that the direction field is invalid, so the stock buying and selling financial transaction order instruction is not processed continuously. The embodiment automatically checks the financial transaction order instruction of the cross-border joint order bus throughput, judges the data validity and business validity of the order elements of the domestic and foreign systems according to the dynamically configured multiple system order standards, identifies the abnormal order instruction in advance, and triggers asynchronous alarm.

[0059] In an embodiment, after the step 102, the method comprises:

[0060] The financial transaction order instruction is converted into a binary stream through serialization technology and saved to the SQLite database.

[0061] In the embodiment, for each financial transaction order instruction received through the cross-border joint order bus technology, the SQLite technology is used to save it, so as to ensure the high availability of the cross-border joint order bus technology. Of course, the message format of the saved financial transaction order instruction has been converted into the internal message format through the dynamic configuration in the adaptive order information collection algorithm. When the cross-border joint order bus technology abnormally, the financial transaction order instruction saved through the SQLite database can be used for quick recovery, so as to ensure the stability of the cross-border joint order bus technology. In a specific application scenario, the cross-border joint order bus technology can complete the financial transaction order instruction recovery process within 10 ms.

[0062] In a specific embodiment, as Figure 2As shown, the initiator (for example, an overseas system) initiates an order transaction instruction, and based on the built-in risk control in the order transaction, receives the order transaction instruction through an adaptive order information collection algorithm in the cross-border joint order bus technology, and stores the order transaction instruction into a lock-free atomic communication bus. The lock-free atomic communication bus performs information alignment and information compression on the order transaction instruction to make the order transaction instruction adaptive to other systems, and sends the order transaction instruction to the receiver (for example, an inland system) through the cross-border joint order bus technology, and performs built-in risk control and entrusts submission by the receiver. When receiving a transaction return sent by the receiver, the transaction return is stored in the lock-free atomic communication bus, and the transaction return is fed back to the initiator.
