BiasBand

BiasBand is an indicator designed to provide a robust visual bias (LONG / SHORT) based on envelope bands (MA ± %) calculated on the chart’s timeframe.
When a close breaks beyond the bands the indicator sets the state (flip) and saves a pivot (option to use the confirmed basis from the previous bar). To reduce false signals it includes:

• Pivot buffer percent — a percentage hysteresis around the pivot to avoid micro-flips.
  
• Recovery check — if the basis crosses the pivot (beyond the buffer) the state is updated even without a band breakout.
  
• Slope-based backup — ability to force a flip when the basis moves persistently in the opposite direction for N consecutive bars.
  
• Session shading (optional) and debug label for tuning.
  

BiasBand is intended for intraday traders and scalpers who want a quick indication of market bias with extra filters to reduce noise and false flips. The envelope always follows the chart timeframe (multi-TF consistency).

Main inputs (quick explanation)

• MA Period (lenEnv): period of the moving average used as the basis for the envelope.
  
• Envelope Percent (pctEnvIn): width of the bands expressed as a percentage of the basis.
  
• Pivot buffer percent (pivotBufPct): hysteresis around the pivot to avoid micro-flips (e.g. 0.001 = 0.1%).
  
• Save pivot = basisRaw[1] (pivotUsePrevBar): when true, the pivot is saved from the confirmed previous basis bar instead of the current basis — reduces intrabar noise.
  
• Enable basis-slope flip / Consecutive bars (basisSlopeBars): backup mechanism that forces a flip when the basis moves persistently for N bars.
  
• Session shading: optional hourly shading over a chosen time range.
  
• Show debug label: displays useful values for the latest bar to help parameter tuning.
