The method can be executed by a snapshot market distribution device, which can be implemented by software and/or hardware, and can be integrated in a device with data operation function, such as a desktop computer or a server. Referring to fig. 1, the method of the present embodiment specifically includes the following steps:
and S110, acquiring a resource code of the market data.
The market data refers to important financial information such as stocks, futures, funds, precious metals, foreign exchanges, and the like. The resource code refers to a code corresponding to a resource name, for example, a stock code, a futures code, a fund code, a precious metal code, a foreign exchange code, and the like.
In order to improve the transmission and calculation efficiency of market data, the embodiment adopts a field programmable gate array (FPGA for short) to receive market data sent by a stock exchange at set time intervals and perform accelerated processing on the market data, the market data subjected to accelerated processing is output to a software side, and the software side extracts resource codes of the market data and executes operations of generating and distributing snapshot market. The FPGA receives the market data and accelerates the market data, so that the transmission speed of the market data can be increased, and the subsequent snapshot generation speed and distribution speed can be increased. Alternatively, the set time period may be a 3 second, 5 second, or the like time period.
S120, determining a target address corresponding to the resource code, and determining a target storage area of the resource code based on the target address.
The target address corresponding to the resource code refers to the snapshot address corresponding to the resource code. The target storage area refers to the storage space allocated to the resource corresponding to the resource code at the stock exchange end.
It is understood that each resource code corresponds to a snapshot address, and each snapshot address corresponds to a unique storage space. When the resource code is obtained, the corresponding address is searched from the software side based on the resource code to be used as a target address, and the target address is used as an index to search the corresponding storage space to be used as a target storage area.
And S130, generating snapshot quotations of the quotation data based on the quotation processing rules of the predetermined resource codes.
The market processing rule may include processing logic of all nodes of each resource. For example, processing logic including nodes for order-by-order, deal-by-deal, exchange original snapshot, buying and selling directions, etc.
In an optional embodiment, the generating a snapshot market of the market data based on the market processing rule of the predetermined resource code includes:
step S1, determining whether a snapshot update exists in the target storage area;
step S2, if the snapshot update exists, and the value matched with the resource code is searched from the quotation data packets pre-stored in the target storage area, the change number of the quotation data packets in the target storage area is updated;
step S3, if the snapshot update exists and the value matched with the resource code is not found in the quotation data packets pre-stored in the target storage area, storing the current value and the change number of the resource code into the quotation data packets in the target storage area, and sequencing the values in the quotation data packets.
Specifically, in step S1, the snapshot behavior in the target storage area is obtained in real time, the snapshot behavior at the current time of the resource code is compared with the snapshot behavior at the previous time, and if the snapshot behavior at the current time is different from the snapshot behavior at the previous time, the snapshot behavior of the resource code in the target storage area is determined to be updated; aiming at the step S2, the quotation data packets pre-stored in the target storage area comprise a 10-grade value queue, the value of the resource code is compared with the value in the 10-grade value queue, if the matched value exists, the snapshot quotation at the current moment is added to the pre-stored quotation data packet, or the snapshot quotation at the current moment is deleted from the pre-stored quotation data packet, namely, the change number in the quotation data packet in the target storage area is updated; in step S3, if there is no matching value, it is indicated that no corresponding value is found from the 10 th value order, the value of the resource code is stored in the market data packet, and the values in the market data packet are sorted, so that the snapshot market at the next time of the current time is generated based on the 10 th value queue in the market data packet.
It should be noted that the market data packet includes, but is not limited to, an order data packet, a transaction data packet, and an order data packet. The number of changes includes, but is not limited to, the number of commissions, the number of deals, and the number of waybills. The value-10 queue may include, but is not limited to, a value-10 commission queue, a value-10 deal queue, and a value-10 de-order queue.

Optionally, the performing a distribution operation on the snapshot market based on the stored snapshot data in the target storage area includes: performing ping-pong operation on the stored snapshot data to copy the stored snapshot data from the target storage area to a corresponding new storage area; and determining a market situation type corresponding to the snapshot market situation, updating relevant parameters in the commission/commission queue in the new storage area based on a distribution rule corresponding to the market situation type and the snapshot market situation, updating the new storage area to a pre-established snapshot address table, and distributing the updated relevant parameters in the commission/commission queue in the new storage area to a target application.
The ping-pong operation refers to a process of copying data in the ping address to the pong address. The market types include: a transaction-by-transaction delegation type, a transaction-by-transaction type, an exchange original snapshot type, etc. The purchase/sale queue can be understood as the purchase/sale direction and can comprise related parameters such as the lowest price, the bargain price, the highest price stop-and-go price, the drop-and-stop price and the like of the purchase/sale direction of each resource. The target application refers to the stock exchange application of each stock exchange, and a financial practitioner can acquire snapshot quotations from the stock exchange application, so that the financial practitioner can make decisions and adjustments on exchange products conveniently.
Specifically, when a snapshot quotation is received, if the target storage area is consistent with the ping address, the snapshot data stored in the ping address is copied to the pong address, and the pong address is used as a new storage area; and if the target storage area is consistent with the pong address, copying the snapshot data stored in the pong address to the ping address, and taking the ping address as a new storage area. And then, performing binary protocol analysis on the acquired market data, determining market types corresponding to the snapshot market, wherein each market type corresponds to a distribution rule, extracting relevant parameters in a purchase/sale queue copied in a new storage area according to the distribution rule corresponding to each snapshot market, comparing the values in the purchase/sale queue with the values in the generated snapshot market, updating the relevant parameters in the purchase/sale queue in the new storage area if the values are consistent, updating the new storage area to a pre-established snapshot address table, and distributing the relevant parameters in the purchase/sale queue updated in the new storage area to a target application.

Compared with the scheme that the acquired market data are directly forwarded to the securities trading application at set time intervals, the scheme has the advantages that the requirements of low delay and accuracy of trading of financial practitioners can be met, the financial practitioners can conveniently acquire the snapshot market in real time, and make decisions and adjustments according to the snapshot market acquired in real time.
Example two
On the basis of the first embodiment, the present embodiment refines "determining a target address and a target storage area, and performing a distribution operation on a snapshot market". Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. Referring to fig. 2, the snapshot market distribution method provided in this embodiment includes:
s210, acquiring resource codes of market data.
S220, with the resource codes as indexes, searching the address offset of the resource codes from the pre-established snapshot address table to be used as target addresses of the resource codes, and determining the target storage areas of the resource codes based on the target addresses and the pre-established snapshot storage areas.
Before the resource codes of the market data are acquired, a snapshot address table based on the shared memory and a snapshot storage area based on the shared content are established in advance in the memory on the software side. Fig. 3 is a schematic diagram of a snapshot address table, and fig. 4 is a schematic diagram of a snapshot storage area. The snapshot address table in fig. 3 is composed of a shared memory area with a fixed size, the size of which is 20000 bytes, and is used to store the address offset of each resource code, and the currently acquired resource code is used as an index to search the address offset of the resource code from the snapshot address table, which is used as the target address of the currently acquired resource code. The shared memory area is represented by a matrix, wherein each row of the matrix is represented by a high three-bit map of each resource code (e.g., stock code), and each column of the matrix is represented by a low three-bit map of each resource code (e.g., stock code). The snapshot storage area is composed of a shared memory area with a fixed size, two continuous spaces can be applied for each resource, a snapshot address table is initialized by the address (such as a ping address) of each resource code, and the target storage area of the resource code is searched according to the determined target address and the preset snapshot storage area. For example, if the resource in fig. 4 is a stock, the snapshot quote involves a memory ping-pong operation, applying two contiguous spaces for each stock, and if 5000 stocks are reserved, the memory size is 5000 x 2 x 16048-160480000 bytes.
And S230, generating snapshot quotations of the quotation data based on the quotation processing rules of the predetermined resource codes.
And S240, performing ping-pong operation on the stored snapshot data to copy the stored snapshot data from the target storage area to the corresponding new storage area.
And S250, determining the market situation type corresponding to the snapshot market situation.
And S260, if the market type is an individual consignment type, matching the related parameters of the resource codes with the related parameters in the consignment/consignment queue in the new storage area, and changing the quantity and/or value of the resources in the consignment/consignment queue in the new storage area according to the matching result so as to update the related parameters in the consignment/consignment queue in the new storage area.
Specifically, if the market type is an order-by-order entrusting type, the snapshot market is taken as a market data packet, the order number and the value contained in the market data packet are stored in a pre-established order storage linked list, the order storage linked list stores relevant parameters of an order-by-order transaction type, an order-by-order entrusting type and an order removing type in advance, the relevant parameters of the resource codes are matched with the relevant parameters in an order buying/selling queue in a new storage area (such as a pong address), and if the matching is successful, the quantity of the resources at the gear is added with the quantity of the resources in the order buying/selling queue to record the quantity of the resources entrusted at the gear; if the matching fails, the value and the quantity of the order are stored in an order buying/order selling queue, and the ordering is carried out according to the value, so that the resources with low value are arranged in front and the resources with high value are arranged behind, the information inquiry of the target application is facilitated, and the operation of updating the relevant parameters in the order buying/order selling queue in the new storage area is completed.
S270, if the market type is a transaction type, traversing a pre-established order storage linked list, searching a node corresponding to the resource code and acquiring a corresponding value, updating the quantity and/or the value of the resource in the purchase/sale queue in the new storage area according to the searched node and value, and updating the related parameters of the resource code in the new storage area.
The relevant parameters may include parameters such as the highest price, the lowest price, the volume of bargaining and the volume of bargaining of the resource. Specifically, if the market type is a transaction type, traversing a pre-established order storage linked list, finding a node matched with the transaction and acquiring a corresponding value; subtracting the resource quantity in the transaction from the resource quantity of the value gear in the consignment/consignment queue, comparing the value in the transaction market with the highest price and the lowest price of the resource in the new storage area in the snapshot storage area, and updating the highest price or the lowest price of the resource in the new storage area; and further updating the volume and the volume of the transaction of the resources in the new storage area. For example, volume of transaction is original volume of transaction in snapshot + volume of transaction; the initial bargain amount + the bargain price/10000 times the bargain amount in the snapshot.
S280, if the market type is the original snapshot type of the exchange, extracting relevant parameters from the snapshot market, and updating the relevant parameters in the buying/selling queue in the new storage area based on the extracted relevant parameters.
The exchange original snapshot type refers to various states of recording information at a certain moment. The market situation type is the original snapshot type of the exchange, and relevant parameters are extracted from the snapshot market situation. For example, related parameters such as opening price, yesterday collecting price, rising price, falling price and the like in the snapshot market are extracted, and related parameters in the commission/commission queue in the new storage area are updated based on the extracted related parameters.
S260 to S280 in fig. 2 are executed in parallel. In specific implementation, S260 to S280 may also be executed in sequence based on the order according to the time points, that is, the step of updating the relevant parameters in the consignment/consignment queue in the new storage area is executed first, where the market type is the distribution rule corresponding to each consignment type; then, the step of updating the relevant parameters in the buying/selling commission queue in the new storage area is executed, and the whole step of updating the relevant parameters in the commission/commission queue in the new storage area is completed.
And S290, updating the new storage area to a pre-established snapshot address table, and distributing the updated related parameters in the commission/commission queue in the new storage area to the target application.
