Trading Activity Index (Zeiierman)

5 小時前

█ Overview
Trading Activity Index (Zeiierman) is a volume-based market activity meter that transforms dollar-volume into a smooth, normalized “activity index.”

It highlights when market participation is unusually low or high with a dynamic color gradient:

• Light Blue → Low Activity (thin participation, low liquidity conditions)
  
• Red/Orange → High Activity (active markets, large trades flowing in)
  

Additional percentile bands (20/40/60/80%) give context, helping you see whether the current activity level is in the bottom quintile, mid-range, or near historical extremes.

█ How It Works

⚪ Dollar Volume Transformation
Each bar, dollar volume is computed:

float dlrVol  = close * volume
float dlrVolAvg = ta.sma(dlrVol, len_form)

• Dollar volume = price × volume, smoothed by a configurable SMA window.
  
• The result is log-transformed, compressing large outliers for a more stable signal.
  

⚪ Rolling Percentiles & Ranking
The log-dollar-volume series is compared to its rolling history (len_hist bars):

float p20 = ta.percentile_linear_interpolation(vscale, len_hist, 20)
float p40 = ta.percentile_linear_interpolation(vscale, len_hist, 40)
float p60 = ta.percentile_linear_interpolation(vscale, len_hist, 60)
float p80 = ta.percentile_linear_interpolation(vscale, len_hist, 80)

• A normalized rank (0–1) is produced to color the main Trading Activity line.

█ How to Use

⚪ Detect High-Impact Sessions
Quickly see if today’s session is active or quiet relative to its own history — great for filtering setups that need activity.

⚪ Spot Breakouts & Traps
Combine with price action:

• High activity near breakouts = strong follow-through likely.
  
• Low activity breakouts = vulnerable to fake-outs.
  

⚪ Market Regime Context
Percentile bands help you assess whether participation is building up, in the middle of the range, or drying out — valuable for timing mean-reversion trades.

• Above 80th percentile (red/orange) → Market is highly active, breakout trades and trend strategies are favored.
  
• Below 20th percentile (light blue) → Market is quiet; fade moves or wait for expansion.
  
• Watch transitions from blue → orange as a signal of growing institutional participation.
  

█ Settings

• Formation Window (bars) – Number of bars used to average dollar volume before log transform.
  
• History Window (bars) – Lookback period for percentile calculations and rank normalization.
