MODIFYING THE EXISTING EA, AND ADDING A MATHEMATICAL FORMULAE BASED SCANNER OF WATCHLIST CURRENCIES

HI, CODERS, GOOD DAY TO ALL

I WOULD LIKE TO MODIFY AN EXISITING EA, BY ADDING A MATHEMATICAL STRATEGY BASED SCANNER, WHICH  SHOULD SCAN THE WHOLE WATCHLIST, FOR A CURRENCY PAIR, WHICH SATIFIES THE PARTICULAR MATHEMATICAL FORMULA (BASED ON CANDLE OPEN HIGH LOW CLOSE, AND CUSTOM INDICATORS,, )) 

IF ANY SYMBOL IN THE WATCHLIST,  SATIFIES THE SYMBOL ,,, THE WHOLE MERGED EA, SHOULD TRADE.

EXISTING EA, HAVE EVERYTHING.. IT JUST NEEDS A SYMBOL TO TRADE,, WHICH IT SHOULD GET FROM THE SCANNER.

BUT THE SIGNAL HAS A TIME PERIOD VALIDITY IN TERMS, OF NO. OF HOURS, AND DAYS,,

AFTER THAT IT LOOKS FOR ANOTHER SIGNAL, AND HALT NEW TRADES,  BUT CONTINUE TO MANAGE EXISTING TRADES,,

THE WHOLE IDEA IS THIS..

I HAVE A DETAILED DOC, WHICH I WILL GIVE TO THE SELCETED CODER.

.THANK YOU;
