Using AT, MQL5 or any other signal service always comes with issues. You will never get the same results, sometimes the difference will be huge. There are slippages, glitches in software, latency, missed trades... All this eventually leads to different results.
I am not saying you cant be profitable but the risk:reward is very bad. There are no good accounts on Autotrade so I dont understand why would anyone still want to use it.
