Dobrusky Volume Pulse

What it does & who it’s for
Volume Pulse is a lightweight, customizable volume profile overlay that shows traders how volume is distributed across price levels over a chosen lookback window. Unlike standard profiles, it also maps cumulative buy/sell pressure at each level, so you see not just where volume clustered, but which side dominated.

Core ideas

• Cumulative volume by price: Builds a horizontal profile of traded volume at each level, based on user-defined depth and resolution.
  
• Directional pressure mapping: At every price level, the script accumulates bullish vs. bearish volume based on candle closes vs. opens, providing a directional read on whether buyers or sellers had the upper hand.
  
• POC: Automatically highlights the Point of Control (POC) — the level with the most activity.
  
• Customizable presentation: Adjustable profile resolution, bar width, offset, colors, and whether to show cumulative, directional, or both.
  

How the components work together
The profile provides the “where,” while the buy/sell mapping adds the “who.” By combining these, traders can see whether a high-volume node was buyer-driven absorption or seller-driven distribution — a distinction classic profiles don’t reveal. This directional overlay reduces the guesswork of interpreting raw volume clusters.

How to use

• Apply the overlay to your chart.
  
• Watch the POC and areas of significant increase or decrease in volume (and pressure) as natural magnets or rejection areas.
  
• When trading intraday, I've found that higher timeframe volume levels act as strong magnets. In the chart, you can see the volume levels I've drawn on the SPY daily chart. These levels are targets I use when trading the 5-minute chart.
  
• Pay attention to color dominance at those zones — green-heavy nodes suggest buyer control; red-heavy nodes suggest seller control.
  
• Combine with time-based volume tools and price-action for a more comprehensive trade plan.
  

Settings overview

• Lookback depth: Number of bars used for profile calculation.
  
• Profile resolution: Number of horizontal bars to split volume across price.
  
• Bar style: Width, offset, and multiplier for scaling.
  
• Toggle layers: Choose cumulative, directional, or both.
  
• POC display: Optional highlight of the most traded level.
  

Limitations & best practices

• This is a contextual overlay, not a trade-signal system.
  
• Works best on liquid instruments (indices, futures, major stocks, liquid crypto) where volume distribution is meaningful.
  
• Directional mapping uses candle body bias (close vs. open), not raw order flow. For full tape analysis, pair with actual order flow data.
  

Originality justification

• Dual profile: combines cumulative volume-by-price and buyer/seller pressure per bin (close vs. open) — not a standard VP clone.
  
• From-scratch binning + POC in a single pass for speed; no reused libraries.
  
• Flexible display (cumulative / directional / both) with independent resolution, width, and offset for intraday or HTF use.
  
• Clear visuals (optional POC, balanced node coloring) and open-source code so traders can audit and extend.
