This is the simple strategy using indicator stochastic oscillator (mt4 default indicator) and candle pattern.As we know that stochastic can identify overbought and oversold.So the idea is when market already oversold or overbought,then we find candle pattern there,we make OP.
See this image (click to enlarge):
On the image above ;
Time Frame H4
SELL when Stoch Overbought + Candle Pattern
Close when Stoch cross level 20 without waiting for candle closed.
Perhaps,you need a lot of time to get the signal,but you can open several pairs at the same time to save your time. Happy trying and good luck!
