Volume mura vision

8 thg 9

Overview
A simple, readable volume tool that highlights volume spikes relative to a moving-average baseline. Bars are color-coded:

• Spike UP (price closed up)
  
• Spike DOWN (price closed down)
  
• Below-average volume
  
• Near/above MA but not a spike (neutral)
  

Optional: plot the selected Volume MA as a line.

How it works
1. Compute a Volume MA (SMA/EMA/RMA/WMA) over Volume MA Length.
2. A spike occurs when Volume ≥ MA × (1 + Spike threshold%).
3. Bar color:

• Spike + up candle → Spike UP color
  
• Spike + down candle → Spike DOWN color
  
• Volume < MA → Below-MA grey
  
• Otherwise → Base grey
  

4. The MA line can be shown/hidden.

Inputs

• Volume MA Length (len) — lookback for the volume moving average.
  
• Spike threshold (%) over MA (thr_pct) — how far above the MA a bar must be to count as a spike.
  
• MA Type (ma_type) — SMA / EMA / RMA / WMA for the volume baseline.
  
• Show MA line (showMA) — toggle the MA overlay on the volume pane.
  

Colors

• Base grey — volume near/above MA but below spike threshold.
  
• Below-MA grey — volume below the MA.
  
• Spike UP — spike on an up candle (close ≥ open).
  
• Spike DOWN — spike on a down candle.
  

Alert
Volume spike — fires when Volume ≥ MA × (1 + threshold).

Usage tips

• Lower the threshold to catch more activity; raise it to see only major bursts.
  
• Shorter MA length reacts faster (more spikes); longer length smooths noise.
  
• Combine with price action (breakouts, reversals) to confirm whether spikes signal participation or exhaustion.
