Thanks for the info. This helps everyone considering this EA.
Don't agree with posts above. I use this system during many years and it works well for me. You can check internet and see that there are a lot of users with stable results during long time. I'm not protect it or something like that, just share my results. I can make a note that it's better to be careful with settings because if you will make one single mistake you will get loss trades but after that you will say that this system is bad.
Their support usually good but sometimes they can have delays in replies. Like it was in the last time when I not got reply during 3 days but they said that it was because of holidays. They have millions on their accounts but can't provide support during holidays. :)
Concerning settings. As I said I asked them about some additional explanation or maybe text file. Or of course better pdf file with details concerning every setting because they have only explanation in User Guide. For experienced traders it will be comfortable to see some additional materials. They answered that they will take into account that for the future updates. Still wait...
In general I can say that if you will use it carefully and will be in contact with support, this gps robot provides stable results. On my account (friend name because I have Italian passport) I have already almost 200% of clear profits. I also have other accounts and one pamm account where I use gps ea and I have good results with it. In some periods it closes very impressive trades. I posted it in other thread.
Once we realize that imperfect understanding is the human condition there is no shame in being wrong, only in failing to correct our mistakes.
