I have also struggled in choosing an indicator to use before but but then focused on ATR, Stochastics, Fibonacci, Bollinger Bands, Keltner Channel and Moving Averages that I incorporated into one indicator producing possible buy and sell signals. I also backtested this strategy since 2016 and using it for the past months which is quite good.
