Idea Behind:
Buying the short-term trend that shows a pin-bar candlestick pattern. Meant to be traded on a daily chart / higher timeframe.
To determine the short-term trend we use short EMA such as 8-16-30 and check the slope of each one, and definitely, the shorter one must be above the longer one for an uptrend. Vice versa for a downtrend.
To determine a pin-bar candlestick, I calculate that the body size (open to close) is at maximum a-third of the candle size (high to low). Besides that, I ensure that the close of the candle is above the shortest MA for bullish and below it for bearish.
As extra filters to reduce trade numbers:
1. Longer MA Filter = You can turn it off if you think the higher timeframe filter is unnecessary.
2. Slope Filter = To ensure the slope of the shorter MA is steeper rather than the mid-MA.
3. Size Filter = To check whether the overall candle size (high to low) is bigger than the ATR number. When the size filter is turned on, it removes small insignificant candles.
PS: Don't trade anything live unless you find it comfortable after backtesting it by yourself.
