The most decent strategy would be analyzing the market, There are plenty of methods to do so (better check one of the forex sites for that), I don't recommend binary though since it's closer to gambling than forex trading since no one can exactly make a prediction for ~1 hour except randomly.
I've heard my friends on facebook talking strategy Binary play without the need for market analysis this strategy is what I mean
so they used some kind of specific methods on the direction of markets in the chart These strategies vary according to the condition of the chart, if you know a method or strategy like this?
