Modify this Expert Advisor to make it work properly

HI,

I require modify the EA for MT5 that satisfy the following conditions:

-The fields "Day Open" "Hour-Min(Broker)" "Day Close" must work and update automatically from week to week (now I have to close and restart the mt5 every weekend because the days work)

-MM field does not work with stock markets (wrong values). I would like MM to work as a percentage of the account equity (Forex, Indices, Metals, Stock Markets)

-Backtesting section does not allow you to automatically optimize order processing hours (only manual)

-Insertion auto of holiday days (es. American stock Exchange date close) and update automatically

-cleaning up parts of the code that are not needed
