Generally speaking, there are two main categories of strategies when it comes to binary trading:
Type 1: Strategies based on betting models - Those strategies presume that using specific patterns in terms of investment amounts and the right timing can generate profit no matter if the trader is skilled or not at market prediction. Those strategies presume that in certain situations you can design your option buying strategy to give you a high probability of winning. In this category you will find betting pattern strategies like The Grinding Strategy or strategies based on trading the news.
Type 2: Strategies on how to predict the direction of the market better - In this case the strategies are based on simple technical and statistical evidence that in some circumstances the market has greater chances to move in one direction over another. While technical analysis can be pretty complicated, there are much simpler ways of interpreting the charts, especially when it comes to binary trading.
