Add indicator in EA

Hello I have an correlation EA and I need it to buy / sell only based on an indicator, the indicator will be passed to the programmer.

Symbol 1 is BASE, symbol 2 is HEDGE.

Always input to BASE, prices closing above the INDICATOR, when GREEN, buy in BASE, sell in HEDGE.

((((TakeProfit Output, or if the indicator turns red)))))

Always input to BASE, prices closing below INDICATOR, when GREEN, sell in BASE, buy in HEDGE

((((TakeProfit Output, or if the indicator turns green))))

In addition, I need to add these parameters to Day trader operations.

UseTradingHours = TRUE; // to control the trading hours;

Extern int StartHour = 8;

Extern int CloseHour = 16;

DailyTarget = 10.0; // Once you hit DAILY TARGET, EA stops trading and only retries in the next session.
