EA creation (simple EA) with my own indicator (No.ex4 file available)

Hi, my work order is simple as below:

(1) MT4 EA (not MT5 EA)

(2) I want to use my own indicator (MT4 indicator), not available of .ex4 file.

(3) My indicator create long/short signal and seems to have buffer value. Not sure(Please see the attached screenshot).

(4) I need to EA that open when signals occur(long and short).

(5) I need to close that trade BASED on holding time such as 5min, 15min,30min, 1H, etc. since opened. I need to choose so as EA parameters.

(6) Above time period (N bar close) close trade AND stoploss at price of the previous candle open price whichever comes first ! 

(7) If holding positions, then automatically close at HOUR:MINUTE regardless profit or loss positions.

That's it. If not clear my order, conditions, and requirements, please let me know.

My budget is hard-set @$30.00. No negotiation.

Thank you.
