Color Coded Volume Indicator

Overview
Splits each bar’s total volume into estimated buy-side vs. sell-side components and displays them as stacked two-tone columns (red = sell, green = buy). Axis labels and tooltips use “K”/“M” formatting.

Features

• []Stacked Two-Tone Columns
  
  • []Red Base: estimated sell volume (50% opacity)
    []Green Top: remaining buy volume (50% opacity)
    
  []Automatic K/M Formatting via [code]format=format.volume[/code]
  []Zero Baseline for clean reference at zero
  []Positive-Only Bars (no negatives)
  

How It Works

1. []True-Range Guard
   Skips bars where [code]high == low[/code] to avoid divide-by-zero.
   []Volume Split

   BuyVol = Volume × (Close − Low) / (High − Low)
   SellVol = Volume × (High − Close) / (High − Low)

   
   Both series clamped ≥ 0.
   
2. Layered Plot
   Draw semi-transparent green at full height, then overlay red sell portion.
   

Usage

• []Open TradingView’s Pine Editor
  []Paste in the full script
  []Click “Save & Add to Chart”
  []In the Publish dialog, title it “Color Coded Volume Indicator” and paste this description.
  

Interpretation

• []Green-dominant bars → strong buying pressure
  []Red-dominant bars → strong selling pressure
  
• Equal halves → balanced activity

Added Normalize volume on opening and closing candles to reduce the size of the opening and closing candles, which almost always are unusually large, but don't add a lot of value to most users. When you normalize, it reduces their size and adds a text label to still show you the size.

Color Coded Volume Indicator

Normalize session extremes to 15:58 volume

This indicator splits each bar's volume into buy (green) and sell (red) components and, optionally, normalizes the first and last two session candles to the previous-1 bar's volume (i.e. the 15:58 bar on a 1-min chart).

Use on intraday charts up to 5-min. When Normalize volume on session extremes to 15:58 volume is enabled, the 9:30, 15:59, and 16:00 bars plot at the 15:58 volume level, preserving each bar's original buy/sell ratio. Labels show the actual raw volume (K/M format).

1. InputsNormalize volume on session extremes to 15:58 volume (bool): Enable cap on 9:30, 15:59 & 16:00 bars
   
2. Volume SplitBuy volume = max(volume * (close - low) / (high - low), 0)
   Sell volume = max(volume * (high - close) / (high - low), 0)
   
3. Normalization LogicDetect 15:58 candle → latch its rawTotal as reference
   Session extremes = 9:30, 15:59, 16:00 bars
   On extremes: plot total = reference; plot sell = reference * (sell/total)
   All other bars: plot actual rawTotal/split
   
4. Labels
   • Plain text (no box) above each extreme bar
     
   • Shows actual raw volume in K/M format

Update v1.1

• Added moving average with selectable type (SMA, EMA, WMA, VWMA) and adjustable length — works just like the built-in Volume indicator.
  
• Improved the opening bar normalization: the 9:30 bar is now sized using the average volume of the 9:31 bar over the last 5 sessions, rather than the previous day's 3:58 bar. This provides a more relevant reference for the opening spike.
  

Why shorten session extreme bars?
The 9:30 open and 4:00 close bars typically have 5-10x normal volume due to order accumulation (overnight orders executing at open, MOC orders at close). Left unscaled, these bars dominate the y-axis and compress all other bars into an unreadable sliver. By capping their display height to a reference volume — while preserving the buy/sell ratio and labeling the actual volume — you get a readable chart without losing information.
