This Ea is very good , I tested it , great results .... if you stay in momey management

Hi..this Ea look good..can u code this ea to "close by signal" and new signal will be open folow the supertrend

I'm interested in this EA. Can anyone share results on M15, especially on EUR/USD or XAU/USD? Thanks!
Also what inputs are good for this, account size 600 to 700dolars?
