The manual for EA Happy Gold

Pitty, this EA is excellent, I need the manual. I have one from the Internet, but it is old, and if I'm using their settings the result is not good.
Is the old version different from the latest? It may be necessary to try changing the settings to find the best settings.
 
I did it and achieved some good results in backtesting. I want to know the logic behind picking the daily trade hours. The rest of the parameters are OK.
