Optimize the blind test feature

I hope you can add a blind test feature with random timing that still allows users to see the exact time and values of data releases.

Currently, in blind testing, if you check the "Random Time" option, you can no longer see the exact time the data was released. This is not ideal for strategies that aim to avoid sharp fluctuations at the time of data release (or those that intentionally seek to capitalize on such fluctuations). We hope this can be improved.
