The (virtual) user may initiate both normal and fraudulent transactions.
For a (virtual) platform, a transaction may take both pass and block actions.
Depending on the (virtual) user initiated transaction and the actions taken by the (virtual) platform, there are 4 combinations: normal transaction-clear, fraudulent transaction-clear, normal transaction-block, and fraudulent transaction-block.
Referring to FIG. 3, FIG. 3 is a graph illustrating target score scores; a certain score can be achieved for the (virtual) user and the (virtual) platform each time a transaction is made. These four transaction behaviors set the score obtainable by the (virtual) user and the (virtual) platform, i.e. the target score. One score setting is as follows:
if the (virtual) user initiates normal transaction, if the (virtual) platform takes a release action, the (virtual) platform and the (virtual) user can obtain 3 points; if the (virtual) platform takes blocking action, the platform gets a score of-3, and the (virtual) user gets a score of 3.

initializing a user: generating a certain number of (virtual) users, for example, 1 million users, and randomly allocating a trading strategy to the (virtual) users (which is equivalent to generating a plurality of virtual users in the generating step 11 and randomly allocating a trading strategy to each virtual user in the allocating step 12 in the embodiment of the present invention);
1 round of transaction: all (virtual) platforms and all (virtual) users respectively carry out one transaction;

the following operations are performed every time a one-year transaction is completed (one-year transaction, which corresponds to the metering section in the embodiment of the present invention):
transaction supervision: randomly checking all transactions in the past year according to the proportion of one in ten million, in the random check, if the checked result is that the released transaction is a deceptive transaction, setting the transaction as an invalid transaction, and if the checked result is that the released transaction is a normal transaction, setting the transaction as an effective transaction (which is equivalent to determining a target transaction processing result in all transaction processing results according to a preset sampling rule in the embodiment of the invention);
and (3) statistical scoring: counting the effective transaction scores of all (virtual) users, and sorting the scores from high to low; accumulating the scores of all platform-effective transactions and ranking the scores from high to low

step a-6: b, accumulating the h counter corresponding to the current user transaction strategy obtained in the step a-4 by 1;
step a-7: a, accumulating the w counter corresponding to the current user transaction strategy obtained in the step a-4 by 1;
step a-8: and (e) jumping to the step c, wherein h1, h2, h3, h4, h5, h6, h7, h8 and h9 are high-score user numbers of each transaction strategy, and w1, w2, w3, w4, w5, w6, w7, w8 and w9 are user numbers of each transaction strategy.
For example, referring to fig. 7, fig. 7 is a schematic diagram of an adaptive calculation flow of a wind control strategy, where:
defining the range of plateau high score refers to the plateau with the previous score of 10%, the implementation steps are as follows (a to I):
step A: and initializing an H counter, namely using H1, H2, H3, H4, H5, H6, H7, H8 and H9 as counters, wherein H1 represents the number of platforms using the first trading strategy in the high-ranking platforms, and the like.
