Session VWAP Bands
VWAP with ATR bands for session-based support and resistance
Overview
Session VWAP Bands extend the fundamental VWAP by adding ATR-based upper and lower bands calibrated to current session volatility. VWAP reprices is cumulative volume-weighted average price; bands show where price should trade given current volatility. Prices above upper band = overextended; below lower band = depressed/oversold.
Each session restarts VWAP and band calculations; previous session's bands often provide strong multi-day support/resistance. Using adaptive ATR ensures bands adjust to volatility changes automatically. Professional traders use session VWAP as primary intraday reference with bands for mean reversion entries and overbought/oversold detection. Simple but extremely effective.
Works best on intraday timeframes (5min-4hour) for support/resistance and mean reversion. Daily+ timeframes use alternative support/resistance. Session resets critical; overnight gaps require re-calibration.
Formula
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| ATR Period | Integer | 14 | Period for ATR band width calculation |
| Band Multiplier | Float | 1.5 | How many ATR units wide bands are from VWAP |
| Show Prior Sessions | Boolean | True | Display prior day VWAP/bands for reference |
Common Use Cases
1. Intraday Support/Resistance
Session VWAP acts as primary intraday S/R. Upper/lower bands show where price should respect; touches are scalp opportunities.
2. Mean Reversion Entries
Price touching upper band = overbought; scale shorts. Price touching lower band = oversold; scale longs. VWAP = reversal target.
3. Breakout Trap Detection
Breakout above upper band without volume = weak. Breakout closing back inside bands = likely to reverse that direction.
4. Prior Session Levels
Prior day VWAP often acts as next day's pivot. Prior session bands provide multi-day reference for entries.
Advantages & Limitations
✓ Advantages
- Objective Levels: VWAP/bands are mathematically derived; no subjective line drawing.
- Volatility-Aware: ATR bands adjust automatically to volatility; wide bands in choppy markets, tight in calm.
- Easy to Trade: Clear mean reversion signals; price deviations from VWAP = reversal probability.
- Session Alignment: VWAP reset aligns with trading session; natural daily reference.
! Limitations
- Volume Data Dependent: Accurate VWAP requires reliable volume data; crypto/forex unreliable.
- Strong Trends Ignore Bands: In strong uptrends, price can stay above upper band for hours; not mean-reverting.
- Gap Risk: Overnight gaps render prior session VWAP potentially invalid; restart calculations needed.
- Lag on Sessions Start: First hour VWAP is unreliable; full accuracy by lunch time only.
Tips & Best Practices
⚡ Tune Band Multiplier
Test 1.0-2.0 range; 1.0 = tight bands for range-bound, 2.0 = wide bands for volatile. Calibrate per market.
📊 Watch Band Touches
Multiple touches of same band = strong support/resistance. Break through with volume = genuine breakout vs wick.
🎯 Trade with Trend
In uptrends, buy VWAP bounces off lower band. In downtrends, short bounces off upper band. Follow trend direction.
⚠️ Ignore During Gaps
After overnight gaps or earnings, prior session VWAP is obsolete. Use current session VWAP only after session begins.
Example Strategy
1. Setup: 5min Charts with Session VWAP
Plot 5min chart with session VWAP + 1.5×ATR bands. Mark prior session VWAP as ghosted reference line.
2. Signal: Scalp VWAP Bounces
Price touches lower band = mean reversion long. Price touches upper band = mean reversion short. Use volume to filter fakes.
3. Entry: Reversal Candle at Band
Buy doji/hammer at lower band. Sell shooting star/hanging man at upper band. Stop = band crossed; target = VWAP.
4. Target: VWAP or Opposite Band
Initial target = VWAP line. If VWAP broken, extend to opposite band. Scalp: 3-5 pips; swing: to band reversal.
