When I tried to earn money due to binary options I personally didn’t use any strategy It was so weird, because I udnerstood that I required a strategy but at the same time I was a bit successful without this strategy. I didn’t know what to do, but I should warn you that trading without strategy might lead to unpleasant consequences, hence you have to creater a special one in order to avoid the huge mistakes.
Try to combine various indicators or just pay attention to trends and zones of support and resistance. In fact, binaries are the same to forex, the only distinguishing trait is the mechanism.
