Elsna Supertrend

Elsna SuperTrend is a standard SuperTrend trend-following indicator, drawn as a line on the main chart.

• How it works: it takes the midpoint of each bar, (high + low) / 2, and adds and subtracts the ATR (14 periods by default) times a multiplier (3.0 by default). That gives an upper and a lower band. Each band only moves toward price and never away from it, which makes them “ratchet”.
• What you see:
  • Green line, below price: bullish trend. It follows the lower band and works like a trailing stop.
  • Red line, above price: bearish trend. It follows the upper band.
• Trend flips: it turns bullish when the close breaks above the upper band, and bearish when the close breaks below the lower band. At that point the line switches color and jumps to the other side of price.
• Inputs: only ATR_Period and Multiplier . A larger multiplier gives fewer, slower flips, and a smaller one gives more, faster flips.
