The V2 version of the hang-up test has been conducted for more than 10 days. There is a discrepancy between the hang-up data and the actual profit situation of the account. The specific reasons will be analyzed in the next stage. Based on the fatal defect discovered today, fortunately, it was discovered in time before expanding the impact. Manually close a certain Position in time and correct the version to V3, and restart the hang-up test. I hope that the luck will continue like this for another year.
