There is not best set file for Jacarranda EA. The default setting consider the optimize to work with.
You need good luck and huge margin to maintain your account.
Avoid ranging market, works best in trending market.
News spike and trending market are good friend for this EA, oppositely quite ranging market will kill your account.
Though you run it with the same broker and even same pairs, result might be different depends on the very first time you activate your EA in your MT4.
Choose the pair wisely, understand the market.
Only 0.01 lot for starting, not more then that even if you have a 10k account.
Run an Equity protector EA would be better if you have one.
1.5k to 2k profit per month shouldn't be a problem if the EA didn't blow your account.
That's all I can say. Good luck and pray to your God before you click the 'auto trading' button.
