Open Expert Advisor folder then copy my given EA file and paste it into your mt4 EA folder (open mt4 then goto file from top then mql4 then Expert Advisor folder of mt4).

Default settings are best for some $250 account capital.

M15,M30 and H1 are best timeframes.

EURUSD, GBPUSD, GBPJPY, EURGBP, EURCHF, AUDUSD are some best profitable and low risky pairs.

If your account capital less than 100$ then 2 currency pairs are enough at a time.
