This trading system is known by all market makers and used often times. It is too easy to understand and apply.
Buy if there is ema (21, 200) and fibo retracement level (38, 50, 61) in an uptrend (4H chart)
Sell if there is ema (21, 200) and fibo retracement level (38, 50, 61) in a downtrend (4H chart)
It is better to accompany by a candlestick pattern like engulfing bar, pinbar, harami (inside bar), doji, tweezer tops/bottoms etc.
