There are many good technical indicators you can use in forex trading,but the best indicator i will suggest for you is to use an indicator called moving average convergence divergence(macd),the indicator helps you to determine the market forces that is in control at a particular moment,the indicator compares price and the behaviour of buyers and sellers,for example if the price of a particular forex pairi is getting higher and the indicator is saying the buyers are low compared to the seller then that is a sign that the bullish trend is about to change
