Other systems I do not know very well. But some systems I can give a few my opinions.
I am comfortable with Izaklab's SL, but some trades show losing pips at lower than -100, I don't know why? And Izaklab's monitoring time in FXAuto is a little short, we can not get more information of it's trading behavior.
Quant's SL is too large at 300, this means high risk even it has great sum profit. If you have low deposit, I suggest do not set too much lots for it.
ForexGear has a good history, but this signal provider is very interesting! When he opened a trade, after a few minutes this trade always started losing profits! But I think he may have a hedge system that can hedge this trade and take small profits from it.( This is just my guess, I do not really know how does it works.) We can see a lot of small profitable closed trades in his history. But the first, biggest losing trade, he just let it be pending and wait for the price turning back. So you can see this time, one pair USDJPY shows -336pips, one pair EURJPY shows -385pips, one pair AUDJPY shows -335pips and one pair GBPJPY shows -1020pips! So if your account can handle so many negative pips, maybe you can give it a try.
And I think when you had a great lost with one system, you should not abandon it immediately. The next time there may be a higher chance that this system can make a good profit. After it make 1 or 2 good trades, then you can decide to abandon it or not. So that you will not lose too much money with this system.
Now I am also searching good systems. I want they can cover each other's lost and make a stable profit in a long term, but I still can not select the systems as perfect as I want. The FXAuto system is not so easy as I originally thought!
