I am founding this indicator past 1 year.
The rule :
Buy when the blue dot appear, sell when the yellow dot appear.
This indicator will work maximal in trending condition in all time frame and all pair, so this indicator will be profitable when the market is volatile, for example in European session.
Look this picture (EURJPY in M15 Time frame)
Maybe you can try this indicator in demo account first to know the character more detail
enjoy it.
