This is one of those system I bought and never used. It uses binary betting. The problems is you have to wait for price to reach certain target and then execute it manually, the stop loss is twice as big as the take profit. When I backtested it - it did seem profitable. The problem with this type of trading is you can't set pending orders to open your trade, and once its open you can't set take profit or stop loss levels. All trades have to be executed manually - so you could end up babysitting a trade from 7am GMT to 19:00 GMT. But most trades are normlly open for a few hours. I just didn't like t idea of being sat infront of the computer all those hours - have a 5min break and you could miss the trade.
