Hi AhmadIf you are using EA based on you own strategy on which you have practiced manually for a long time and succeeded, you will definitely be success all the time when trading same on auto, but if you are using any random EA from the market whose nature of trading or strategy you doesn't know, you can lose even a million.
Before using any EA, you must know every option of it in case if order goes opposite so what action your EA should take and that you can only get from your own designed robot, not from 3rd party.
Any EA should have basic functions such as lot, tp, sl, martingale, trail with option to turn then ON and OFF so you can control your trades by any means.
Don't be so efficient or smart that your SL will save you, be aware, brokers they print extra points in candle to hit SL fast then to hit TP. They does it so fast to hit sl like you feel that either market bounce or dropped and reverse. Not every traders knows this but if you install different brokers mt4, you can simply check it with the pivot points or simply check the charts of 4 Jan 2019. You will see different drop prices.
Martingale EA's with proper breakeven, pip distance and multiplier can save traders account in most cases if they hold enough balance to bear it. Not every trader knows that GBP pairs consume double than any other currency cross lot and distance for their martingale is also different than other currency crosses, so their account gets burst usually when they trade GBPUSD, EURGBP or GBPJPY using same settings of other currency pairs. You don't use hand break all the time, but you use it when it is required and that is the reason that every car has hand break.
So it's not always EA, it's your experience and complete hands on EA is also very important.
Bottom line is, before using any EA, you must know it's strategy and it should have proper basic options to control.
Can you please tell me what's most profitable EA and Settings ?
I've done testing with many EA (with your link) but can't find any automatic with consistently .
Thank you
