Supertrend indicator used in mt5 only

• Purpose: The SuperTrend indicator tracks price trends, plotting a line that follows the trend direction (up or down) and optionally fills the area between the trend line and the closing price
• Plots:
• • SuperTrend Line: A colored line (green for uptrend, red for downtrend) plotted below the price in uptrends and above in downtrends.
  • Filling: Optional filled area (bisque/pale green) between the SuperTrend line and the closing price, shown only if Show_Filling is true.
• Logic:
  • Calculates ATR using the iATR function to measure volatility.
  • Computes a middle line ((high + low) / 2), upper band (Middle + Multiplier * ATR), and lower band (Middle - Multiplier * ATR).
  • Determines trend direction:
    • Uptrend (trend = 1): When the closing price exceeds the previous upper band.
    • Downtrend (trend = -1): When the closing price falls below the previous lower band.
    • Maintains trend continuity if no crossover occurs.
  • Adjusts bands to prevent unnecessary fluctuations (e.g., lower band doesn’t decrease in an uptrend).
  • Sets the SuperTrend line to the lower band (uptrend) or upper band (downtrend), with color changes based on trend direction.
• Buffers: Uses 9 buffers:
  • Filled_a, Filled_b: For the optional filling area.
  • SuperTrend, ColorBuffer: For the trend line and its color.
  • Atr, Up, Down, Middle, trend: For internal calculations.

Functionality

• Trend Identification: Signals bullish (up) or bearish (down) trends based on price position relative to bands.
• Visualization: Provides a clear visual with a dynamic trend line and optional price-trend filling for better trend tracking.
• Use Case: Suitable for trend-following strategies, especially in trending markets, but may lag or give false signals in choppy conditions.
