It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.

The transaction data adjustment method of the disclosed embodiment will be described in detail below with reference to fig. 2 to 5 based on the scenario described in fig. 1.

Fig. 2 schematically illustrates a flow chart of a transaction data adjustment method according to an embodiment of the present disclosure.

As shown in fig. 2, the transaction data adjustment method of this embodiment includes operations S201 to S204.

In operation S201, a transaction message is received, wherein the transaction message includes transaction data.

In operation S202, a transaction exposure value and a transaction reference value at a current time are obtained from the transaction data based on the configured exposure adjustment parameters, wherein the transaction exposure value characterizes a transaction risk degree caused when a transaction is performed based on the transaction reference value, and the configured exposure adjustment parameters include a point difference adjustment value.

In operation S203, in the case where the transaction exposure value exceeds the preset exposure threshold value, an interval duration between the adjustment time at which the transaction reference value was last adjusted and the current time is calculated.

In operation S204, in the case where the interval duration exceeds the preset duration threshold, the transaction reference value is automatically adjusted based on the point difference adjustment value, so that the transaction exposure value obtained by performing the transaction based on the adjusted transaction reference value is smaller than the preset exposure threshold.

According to an embodiment of the present disclosure, the transaction message may be an ESP (Encapsulating Security Payload, messaging security encapsulation protocol) transaction confirmation message including transaction details. The transaction data may refer to transaction details such as a transaction benchmark value for a completed transaction, a transaction exchange rate, a transaction point difference, a transaction amount for a completed transaction, a transaction account, a transaction currency, a transaction period, etc., wherein the transaction period may include a spot transaction, a long-term transaction, a fade-term transaction, etc., and the long-term transaction may include a period duration longer than a period duration included in a spot transaction; a swap transaction may refer to a spot transaction and a forward transaction occurring simultaneously.

According to embodiments of the present disclosure, the exposure adjustment parameters may include a currency pair to be adjusted, a transaction deadline, a transaction point difference adjustment value, a level identification of a transaction account, a preset exposure threshold, a time interval, etc., such as an activity level of the transaction account, etc. The transaction point difference adjustment value can be a point difference which needs to be adjusted every time, and the server can automatically call from the database according to the currency pair, the transaction deadline, the grade identification of the transaction account and the like when the adjustment is needed every time. In another embodiment, the point of transaction difference adjustment value may also be set by a business person to increase the flexibility of point of transaction difference adjustment.

According to an embodiment of the present disclosure, the current time may refer to any time after receiving the transaction receipt message, and may refer to an acquisition time when the transaction exposure value and the transaction reference value are acquired. The transaction exposure value and the transaction reference value at the current moment can be the transaction exposure value and the transaction reference value in the transaction process, and the transaction reference value is not changed after the transaction is completed, and as the transaction exposure value is possibly increased according to the transaction reference value, the transaction risk is further caused, the transaction reference value in the transaction message is required to be analyzed and adjusted, so that the adjusted transaction reference value is used for carrying out the transaction in the subsequent transaction process, the risk of the transaction exposure value being increased can be reduced, and the risk of the transaction is reduced.

According to embodiments of the present disclosure, the transaction reference value may refer to reference data referred to in a currency conversion transaction, for example, the exchange rate of a currency to B currency is X, and the transaction reference value may refer to X. The transaction exposure value characterizes a degree of transaction risk that results when a transaction is conducted based on the transaction reference value. For example, the single-side exchange transaction amount of the currency exchange transaction is large, for example, based on exchange rate X, single-side exchange transaction is performed between currency a and currency B, that is, only currency a or only currency B is exchanged, the problem that the single-side exchange transaction amount is large is caused, so that the exchange transaction between currency a and currency B is out of balance, the more unbalanced the transaction is, the larger the transaction opening value can be, the more balanced the transaction is, and the transaction opening value can be smaller.

According to the embodiment of the disclosure, the preset opening threshold value can be adaptively set according to actual transaction conditions. The trade exposure value exceeds the preset exposure threshold value, which can indicate that if the trade is performed according to the trade reference value at the current moment, the trade imbalance degree may be larger and larger, and at this time, the trade reference value needs to be adjusted to restore the balance degree between the trade.

According to embodiments of the present disclosure, the adjustment of the transaction reference value is generally accomplished by a point difference adjustment value. The point difference may be a minimum floating unit, and the difference of the point fluctuation may be a point difference when the transaction reference value is changed. Specifically, the transaction reference value may be a value with a decimal type, the point difference value may be a difference value of point fluctuation after a decimal point of the reference value, and the transaction reference value may be adjusted by using addition or subtraction between the transaction reference value and the point difference adjustment value, so as to influence the transaction open value.

According to the embodiment of the disclosure, the adjustment time of the last adjustment transaction reference value may refer to the time of the last adjustment transaction reference value that is closest to the current time, and the interval duration may be obtained by performing subtraction between the current time and the adjustment time.

According to the embodiment of the disclosure, the preset duration threshold value can be adaptively set according to actual transaction conditions. Under the condition that the interval duration exceeds the preset duration threshold, the characterization can utilize the configured point difference adjustment value to adjust the transaction reference value at the current moment so that the transaction exposure value obtained by carrying out the transaction based on the adjusted transaction reference value is smaller than the preset exposure threshold. For example, the current reference value may be 1.1, the point difference adjustment value may be +0.2, and the adjusted transaction reference value may be 1.3; if the point difference adjustment value can be-0.1, the adjusted transaction reference value can be 1.0.

In the process of the transaction data adjustment method provided by the embodiment of the disclosure, two processing nodes, such as a transaction processing node and a market processing node, may be involved. The following is a detailed description with reference to fig. 3.

According to embodiments of the present disclosure, the processing of the transaction messages herein may be some conventional transaction processing flow, such as transaction message persistence, funds clearing of transaction data within the transaction messages, and the like. Transaction message persistence may be understood as storing transaction messages in a database.

In operation S303, it is monitored whether a component for automatically adjusting the transaction reference value has been turned on.

Operation S304 may be performed in the case of being turned on, and in the case of not being turned on, it may be characterized that the transaction reference value does not need to be automatically adjusted, and may need to be manually adjusted, at which time the ending operation may be directly performed. By providing two adjustment methods, the diversity of adjusting the transaction reference value can be increased.

In operation S304, the transaction data in the transaction message is sent to the quotation processing node through the preset message component.

In operation S305, a transmission record of the transaction data to the quotation processing node is cached in the memory database.

According to the embodiment of the disclosure, after the transaction processing node receives the transaction message from the transaction mechanism, in addition to performing some conventional transaction processing flows, the transaction detail information may be sent to the market processing node through a preset message component, for example, sent to the market processing node through KAFKA, so that the market processing node processes the transaction detail information, and after the market processing node processes the transaction detail information successfully, the transaction processing node feeds back a response file, for example, ack (Acknowledge character, confirm character) to the transaction processing node. In addition, the memory of the transaction processing node also stores transaction detail information and a sending record, which are used for monitoring whether the transaction detail information is sent successfully or not.

Fig. 4 schematically illustrates a process flow diagram of a market processing node according to an embodiment of the present disclosure.

As shown in fig. 4, the processing flow of the quotation processing node may include operations S401 to S416.

In operation S402, a component that automatically adjusts the transaction reference value is turned on. In the case of being turned on, operation S403 is performed, and in the case of not being turned on, operation S416 is performed.

The parameters of the component switch for automatically adjusting the transaction reference value may be stored in a map file (map), with floor, symbol, tenor as key, true or false as value, to form a key-value-to-map file, where true may represent on, false may represent off, and a switch parameter not existing in the map may also represent on. If floor, symbol, tenor are all in an unopened state, no subsequent flow may be performed. Wherein floor may represent a switch identifying the user class identification of the transaction, symbol may be a switch identifying the currency pair, and tenor may identify a switch identifying the deadline of the transaction.

In operation S403, the adjustment parameters in the database are queried.

Inquiring the exposure adjustment parameters, inquiring time intervals (unit seconds), preset exposure threshold values, point difference adjustment values and the like according to floor, symbol, tenor dimensions from a database. If the parameters are not queried, broadcasting to service personnel to prompt that the parameters are not set.

In operation S404, whether the adjustment parameters are all set is completed. In the case where both have been set to completion, operation S405 is performed; in the case that the both settings are not completed, operation S414 is performed.

In operation S405, transaction data is stored in an in-memory database.

In operation S408, whether the interval duration exceeds a preset duration threshold. If the operation is exceeded, operation S409 is performed, and if the operation is not exceeded, operation S416 is performed.

The interval time length refers to a time length between an adjustment time point at which the transaction reference value is adjusted last time and a time point at which adjustment is to be performed now.

In operation S409, the time of this adjustment of the transaction reference value is cached.

If the absolute value of the transaction exposure value is smaller than the preset exposure threshold value, the automatic widening point difference is not needed; otherwise, the transaction point difference needs to be automatically widened to adjust the transaction reference value.

Under the condition that the transaction point difference needs to be automatically widened to adjust the transaction reference value, continuously judging whether the time interval between the current moment and the last automatic widening point difference exceeds a preset duration threshold, for example, whether the time interval exceeds 10s (the preset duration threshold can be adaptively configured through dynamic variables), if the time interval exceeds 10s, the automatic widening point difference is needed, the time of the current automatic widening point difference is updated to a memory database, and if the time interval does not exceed 10s, the automatic widening point difference is not needed. The time of the automatic widening point difference can be recorded in a map, floor+symbol+tenter+side is key, value is automatic widening time, and side can represent the adjustment direction.

In operation S410, the basic transaction point difference at the current time in the in-memory database is queried.

And inquiring the current buying and selling basic point difference and the seqid (identification) of the point difference record according to the product identification (inquired from the original memory database according to the category of the product and the transaction deadline type) from the memory database, symbol, holder, floor_ID and QTY (transaction amount). And under the condition of no inquiry, broadcasting a prompt that the basic point difference is not set to business personnel.

In operation S411, whether the base trading point difference is set. In the case of being set, operation S412 is performed, and in the case of not being set, operation S414 is performed. The base trading point difference may be a point difference obtained from trading data in which the points of the trading reference value fluctuate.

In operation S412, the base trading point difference is adjusted according to the point difference adjustment value to adjust the trading reference value.

In one embodiment, the transaction net exposure value may be an absolute value and may be an exposure value with a direction, such as a positive or negative direction, when the transaction point difference is adjusted. If the net opening value of the transaction is greater than 0, the current opening of a financial institution is a buying value, the point difference of the buying price (bid) quoted by the financial institution can be widened, the widening value can be a point difference adjusting value, and the point difference of the selling price is unchanged; if the net opening value of the transaction is smaller than 0, the current opening of the financial institution is sold, the point difference of the selling price (ask) quoted by the financial institution is widened, the widening value is a point difference adjusting value, and the point difference of the buying price is unchanged.

After the transaction point difference is updated, updated transaction point difference information and updated transaction reference values can be broadcasted.

In operation S413, it is checked whether the adjustment is successful. In case that the verification is successful, operation S416 is performed; in case that the verification is unsuccessful, operation S415 is performed.

In operation S414, the service personnel is notified that the component for automatically adjusting the trading benchmark is turned on, but the open parameter is not set.

In operation S415, a failure to automatically adjust the transaction reference value is reported to the service personnel.

In operation S416, the response file is fed back through the preset message component.

According to the embodiment of the disclosure, the transaction reference value can be adjusted by setting the preset time length threshold value and under the condition that the interval time length exceeds the preset time length threshold value, so that frequent adjustment of the transaction reference value can be avoided. Since the transaction reference value is adjusted for the balance degree of the transaction, if the transaction reference value is frequently adjusted, the transaction reference value may be unbalanced, and the transaction in one direction may be more prone to be performed in the two-way transaction, so that the balance degree of the transaction cannot be well stabilized, and therefore the transaction reference value cannot be frequently adjusted.

Referring to operation S413, the transaction data adjustment method provided by the embodiment of the present disclosure may further include the following operations: checking whether the adjusted transaction reference value is correct; generating a response file which is successfully adjusted under the condition that the adjusted transaction reference value is correct; and broadcasting a second prompt message to the target object under the condition that the adjusted transaction reference value is incorrect, wherein the second prompt message is used for prompting that the transaction reference value adjustment is unsuccessful.

According to an embodiment of the present disclosure, the verification process may include verifying whether the transaction reference value is changed, whether a difference between the adjusted transaction reference value and the transaction reference value before adjustment is a point difference adjustment value, and the like.

According to an embodiment of the present disclosure, in a case where the verification is correct, operation S416 may be referred to, and in a case where the adjusted transaction reference value is correct, a response file is fed back to the transaction service node through a preset message component, so that the transaction service node deletes the transmission record information cached in the database according to the response file.

According to the embodiment of the present disclosure, in case of incorrect verification, a second prompt message indicating failure of automatically adjusting the transaction reference value may be broadcasted to the service personnel with reference to operation S415.

According to the embodiment of the disclosure, the adjusted transaction reference value is automatically checked, so that the adjustment result can be timely obtained, and the intelligent degree of the adjustment transaction data is improved.

Fig. 5 schematically shows a process flow diagram of a transaction processing node after receiving a response document.

As shown in fig. 5, the processing flow of the transaction processing node after receiving the response file may include operations S501 to S502.

In operation S501, a response file is received and recorded.

The response file may be an ack message file fed back by the quotation processing node through the KAFKA message component.

In operation S502, the transmission record information cached in the in-memory database is deleted.

After receiving the response file fed back by the quotation processing node, the quotation processing node can be characterized as having received and processed the transaction data sent by the transaction processing node, so that in order to release the memory, the sending record information including the transaction data, which is cached in the memory database, can be deleted, so as to improve the resource utilization rate.

According to the embodiment of the disclosure, if the response file fed back by the quotation processing node is not received within the preset time period, in this case, the transmission record information including the transaction data, which is cached in the internal database, may be transmitted to the quotation processing node again until the response file fed back by the quotation processing node is received.

According to the embodiment of the disclosure, when the number of times of sending transaction data reaches the preset number of times, the response file fed back by the quotation processing node is not received yet, the response file can be broadcasted to operation and maintenance personnel or business personnel, and the response file can be adjusted in time according to the transaction data, so that the fault of the system is maintained.

According to the embodiment of the disclosure, when the transaction data is sent, the sending record is cached, and when the response file is received, the cached sending record is deleted, so that whether the transaction data is sent successfully can be monitored.

According to the embodiment of the disclosure, the trading exposure value is monitored in real time based on the dimensions of currency pairs, deadlines and the like, whether the trading exposure value exceeds a preset exposure threshold value is judged, if the trading exposure value exceeds the preset exposure threshold value, whether the point difference is widened in the near term (parameter configuration) is judged, the trading reference value is adjusted, if the point difference is not widened, the unilateral quotation point difference is widened, so that the trading reference value is adjusted, and the trade imbalance caused by the fact that the unilateral quotation is clicked by a trading opponent in a large amount in a short term is prevented.

The embodiment of the disclosure provides a method for automatically adjusting a transaction reference value based on a dynamic open-triggered quotation, which can automatically trigger and adjust the transaction reference value when a large number of single-side clicks are performed on a transaction based on a preset point difference adjustment value, and prevent the phenomenon of unbalanced transaction caused by the occurrence of a large number of open-ends.

It should be noted that, unless there is an execution sequence between different operations or an execution sequence between different operations in technical implementation, the execution sequence between multiple operations may be different, and multiple operations may also be executed simultaneously in the embodiment of the disclosure.
