s101, judging whether the transaction quote of a transaction pair in a user transaction order is in a current first price safety interval or not and whether the transaction amount of the transaction pair is in the current first amount safety interval or not according to an inquiry request of a user, wherein the inquiry request is used for indicating the type, the transaction mode and the transaction amount of the transaction pair requesting the transaction in the user transaction order.
In the embodiment of the application, when a user needs to trade, an inquiry request is usually sent out firstly, a digital asset off-site trading device matches a trading offer corresponding to a trading pair according to a trading pair type in the inquiry request, the trading offer comprises a purchase offer and a sell offer of the trading pair, and then matches one purchase offer or one sell offer for the trading pair according to a trading mode in the inquiry request.
Fig. 2 is a flow chart of matching transaction offers to corresponding transaction offers according to an embodiment of the present application. As shown in fig. 2, the step of matching the transaction price to the corresponding transaction price includes:
s201, judging a user type, wherein the user type is used for indicating that the user belongs to a white list user or a non-white list user.
The technical scheme in the embodiment of the application also classifies the user types, and adopts different transaction quotations for different types of users, so that customized transaction services for different users can be realized.
S202, acquiring a transaction price data table corresponding to the user type according to the user type, wherein the transaction price data table is used for representing different types of transaction pairs and corresponding different transaction quotations.
In the embodiment of the application, each type of user corresponds to one transaction price data table, and the transaction price data table comprises all transaction pairs of transaction merchants outside a trading place and transaction offers corresponding to the transaction pairs.
Other user classification mechanisms can be further arranged in the embodiment of the application, multi-level user type classification can be further carried out according to the requirements of users or the usual transaction habits of the users, and each type of user corresponds to one transaction price data table.
And S203, acquiring a transaction price corresponding to the transaction pair requested by the user from the transaction price data table according to the price inquiry request.
In the embodiment of the application, before judging whether the transaction limit of the transaction pair is in the current first limit safety interval, whether the transaction limit of the user exceeds the supply limit of the transaction merchant and whether the transaction limit reaches the limit threshold required by the transaction merchant is also required to be judged, and if the transaction limit of the user exceeds the supply limit of the transaction merchant or the transaction limit does not reach the limit threshold required by the transaction merchant, the current transaction request of the user is rejected.
S102, if the transaction quotation of the transaction pair requested by the user to be transacted is in the current first price safety interval and the transaction amount of the transaction pair is in the current first amount safety interval, returning the transaction quotation and the transaction amount to the user for confirmation.
Of course, if the transaction price of the transaction pair requested by the user to be transacted is not in the current first price safety interval, or the transaction amount of the transaction pair is not in the current first price safety interval, the transaction request of the user at this time is rejected.
In the embodiment of the present application, the first price safety interval and the first limit safety interval are both generated at the time when the current determination step occurs, and the first price safety interval is calculated according to the market price N of the transaction pair requested to be traded by the user at the current time, for example, [ N + 10%, N-10% ], where 10% is a price interval threshold, and in the embodiment of the present application, the price interval threshold is not specifically limited, and needs to be set according to the actual trading situation of the trading market. The first limit safety interval is also set according to the actual trading situation of the trading market, the usual trading habit of the user and the credit situation of the user.
S103, if the confirmation information of the user on the transaction quotation and the transaction amount is obtained, whether the current transaction order is overtime is judged.
In the embodiment of the present application, the user needs to confirm whether to trade with the trading offer and the trading amount in step 102 again, so as to avoid the user from placing a wrong order or losing a wrong trading amount.
Fig. 3 is a flowchart for determining whether a current trade order is time-out according to an embodiment of the present application. As shown in fig. 3, the step of determining whether the current trade order is time-out includes:
s301, if the confirmation information of the user on the transaction quotation and the transaction amount is obtained, the transaction price validity period is obtained.
The valid period of price in the embodiment of the application refers to a time threshold, the digital asset off-site trading device sets the time threshold for all trading orders, the time threshold limits the trading time, and if the trading time is too long, the trading orders are not processed. Further, in the embodiment of the application, the time for determining the transaction information by the user is limited by the transaction price expiry date, and if the user is confirmed for a long time, the time for determining the transaction information by the user is overtime.
S302, judging whether the time between the transaction quotation and the transaction amount returned to the user to be confirmed and the confirmation information of the user is acquired exceeds the transaction price validity period or not. The time for the user to determine the transaction information refers to the time between the time when the transaction quotation and the transaction amount are returned to the user to be confirmed and the confirmation information of the user is obtained.
S303, if the time between the transaction quotation and the transaction amount returned to the user and the confirmation of the obtained confirmation information of the user does not exceed the transaction price validity period, the transaction order is judged not to be overtime.
S104, if the transaction order is not overtime, judging whether the transaction quote of the transaction pair is in the current second price safety interval or not and whether the transaction amount of the transaction pair is in the current second amount safety interval or not.
In the embodiment of the present application, the second price safety interval and the second limit safety interval are both generated at the time when the current determination step occurs, and the second price safety interval, for example, [ M + 10%, M-10% ], is calculated according to the market price M of the transaction pair for which the user requests to trade at the current time, where 10% is a price interval threshold, and the price interval threshold is not specifically limited in the embodiment of the present application, and needs to be set according to the actual trading situation of the trading market. The second limit safety interval is also set according to the actual trading situation of the trading market, the usual trading habit of the user and the credit situation of the user.
The first price safety interval and the second price safety interval in the embodiment of the present application are most likely to be different because the trading price of the digital asset fluctuates from moment to moment, and the secondary check in step S104 is also performed to avoid that the trading price fluctuates too much in the middle time market, and thus the difference is too large.
Of course, if the transaction order is overtime, the user's request for the transaction is denied.
S105, if the transaction quotation of the transaction pair is in the current second price safety interval and the transaction amount of the transaction pair is in the current second amount safety interval, performing the transaction of the digital asset according to the transaction quotation and the transaction amount of the transaction pair. But if the transaction price of the transaction pair is not in the current second price interval or the transaction amount of the transaction pair is not in the current second price interval, rejecting the transaction request of the user.
For the case of rejecting the request of the transaction of the user in the above embodiment, a prompt message may be sent to the user to prompt the user that the transaction cannot be performed for any reason, and then the user may select to re-transact or end the transaction according to the prompt message.
Therefore, the digital asset off-site trading method provided by the embodiment of the application can inquire the trading order requested by the user for trading for multiple times, judge whether the trading quotation and the trading limit are in the safety interval for multiple times at different moments, and avoid the problem that the actual trading price of the user is inconsistent with the expected trading price due to the trading time difference, so that the digital asset of the user is lost.
