Volume Profile POC: Touch-Weighted Key Levels

What Is Point of Control (POC)?

The Point of Control is the price level where the most trading activity occurred over a given period. It acts as a magnet for price — markets tend to rotate around the POC because it represents fair value as perceived by the majority of market participants.

Traditional volume profile indicators only consider traded volume at each price level. AIO Key Volume takes this further by also counting how many times price visited each level (touches), creating a more robust assessment of which levels truly matter.

Touch-Weighted POC Algorithm

Here’s how the algorithm works step by step:

1. Divide the price range into bins: Over the lookback period (default 20 bars), find the highest high and lowest low, then split this range into 25 rows (configurable)
2. For each historical bar: Determine which bins the bar’s range (high to low) covers and distribute that bar’s volume across all bins it touches. Also increment the touch count for each bin.
3. Score each bin: Combined score = volume_score × (1 - balance) + touch_score × balance
4. POC = highest-scoring bin

The Balance Parameter

The balance (default: “Balanced” = 0.5) controls how much weight goes to volume vs touches:

• 100% Volume (balance=0.0): Traditional volume profile — pure volume accumulation
• 75% Volume (0.25): Slightly touch-aware
• Balanced (0.5): Equal weight to volume and touches — recommended default
• 75% Touches (0.75): Emphasizes price revisits over raw volume
• 100% Touches (1.0): Pure frequency — where did price spend the most time?

Why Touches Matter

Consider two price levels:

• Level A: $50,000 volume in one bar (single large candle passed through)
• Level B: $30,000 volume across 8 separate visits

Traditional volume profile picks Level A. But Level B is more significant because price was attracted to it 8 times — it’s a genuine point of interest, not just a zone price passed through once with high volume. The touch-weighted approach captures this difference.

Dual-Timeframe POC

AIO Key Volume computes POC on two timeframes simultaneously:

• Main TF POC (pink line): Computed on the current chart timeframe
• Higher TF POC (blue line): Computed on a configurable higher timeframe (default: 1H)

When both POCs converge on the same price level, it creates a strong support/resistance confluence. When they diverge, the higher TF POC typically acts as the stronger magnet.

VWAP: Two Modes

AIO Key Volume also includes optional VWAP with two calculation methods:

Anchored VWAP (Session-Based)

Resets at the beginning of each trading day. The classic VWAP calculation:

VWAP = Σ(Price × Volume) / ΣVolume

With standard deviation bands at 1σ, 2.168σ, and 2.786σ for statistical price extremes.

Rolling VWAP (Time-Windowed)

Instead of resetting daily, Rolling VWAP uses a dynamic time window that automatically adapts to your chart timeframe:

• 1-minute chart → 1-hour rolling window
• 5-minute chart → 4-hour window
• 1-hour chart → 1-day window
• 4-hour chart → 3-day window
• Daily chart → ~30-day window

Rolling VWAP is more responsive than anchored VWAP and doesn’t have the end-of-day compression problem where anchored VWAP becomes meaningless as the session nears its close.

Moving Average Overlay

A configurable MA (EMA/SMA/WMA, default EMA 89) provides trend context. When POC is above the MA, the structure is bullish. When below, bearish.

Practical Trading Strategy

POC Confluence Entry

1. Identify where Main TF POC and Higher TF POC converge (within 0.5%)
2. Wait for price to pull back to this confluence zone
3. Look for a rejection candle (pin bar, engulfing) at the level
4. Enter in the direction of the MA trend
5. Stop loss: Other side of the POC level
6. Target: Next significant swing high/low or VWAP band

POC as Range Midpoint

In ranging markets, POC acts as the equilibrium. Price oscillates above and below it. You can trade the extremes of the recent range with POC as the mean-reversion target.
