why commercial EAs r considered as scam?
Review sites often are biased. It would be better to look for review outside like forums and blogs not related to the EA owners and supporters.
The least we should do is not to trust such software. Now days, it is trend that scamming brokers launch their own EA which too are perfect for scamming innocent traders. I recently came across such thing with Anyoption, I tried using their auto-trade option and was scammed big time! I set the lowest level in terms of risk/money management, but they changed it to highest and my capital of 15k USD was lost in blink of an eye! Later when I accused them of cheating instead of replying or giving proper answer, they blocked my account entirely. But thanks to WinChargeBack and Rebecca, I put my case forward which was dealt with perfection. My account was unblocked plus they accepted that it was error from their side and I received 13k USD as compensation!
