ExpPinBar - Expert Advisor for Pin Bar Price Action patterns - expert for MetaTrader 5

ExpPinBar Expert Advisor implements a trading strategy based on the Price Action PinBar indicator. Positions are opened based on signals from the indicator. To manage open positions, an extended trailing functionality provided by the trailing library is available: classic, by Parabolic SAR indicator, moving averages AMA, DEMA, FRAMA, MA, TEMA, VIDYA, as well as by the levels of High and Low candlestick shadows.

Settings for the pin-bar indicator:

• Minimum size of a candle from low to high - Minimum size ofa candle (in pips).
  Sets the minimum allowed height of a candle being analysed (the difference between High and Low). Candles of smaller size are ignored by the indicator, which allows excluding insignificant or "noise" candles.
  Increase the value to filter weak signals on low-volatility markets;
  
  
• Maximum size of the candle body relative to its shadows - Maximum size of the candle body (relative to the size of the whole candle, from 0 to 1).
  Defines the maximum allowable size of the candle body (difference between Open and Close) relative to the full height of the candle. The smaller the value, the more pronounced will be the signals with long shadows and a small body - classic Pin Bars.
  To find the most "clean" Pin Bars, use values 0.2 - 0.4;
  
  
• Position of the body relative to the previous candle (from 0 to 1).
  The parameter defines how deep the Pin Bar body can go into the range of the previous candle. The smaller the value, the closer the body will be to the edge of the range, which corresponds to classic reversal patterns.
  Use values 0.2-0.4 to search for signals where the Pin Bar body is located near the border of the previous candle;
  
  
• Aspect ratio of the shadows (coefficient)
  Sets the minimum ratio between the length of the main shadow (upper for Pin Bar for Sell, lower for Pin Bar for Buy) and the opposite shadow. The higher the value, the more pronounced should be the main shadow compared to the opposite shadow.
  Values 1.5 - 2.5 allow filtering signals, leaving only candles with a pronounced long shadow.
