VWAP Suite
VWAP Suite plots three independently anchored Volume-Weighted Average Price lines — Session, Weekly and Monthly — with volume-weighted deviation bands and the previous period's VWAP close kept on the chart as a reference level. Everything is computed from first principles at each anchor, so every line resets exactly where its period starts.
🔶WHAT VWAP IS
VWAP is the average price of the period weighted by how much volume traded at each price. It answers one question: "what is the fair average price actually paid since the anchor?" That is why institutional execution desks benchmark fills against it, and why price so often reacts when it returns there — it is the level where the average participant in the period is at break-even. Above the VWAP the average buyer of the period is in profit; below it, under water.
🔶WHAT IT DOES
Three anchors — Session (resets each trading day), Weekly and Monthly VWAP, each with its own toggle and color. Intraday traders typically work with Session, swing traders add Weekly, and Monthly serves as the higher-timeframe fair-value reference. Anchors that make no sense on the current chart timeframe (e.g. a Session VWAP on a daily chart) hide themselves automatically.
Deviation bands — ±1σ, ±2σ and optional ±3σ around ONE chosen anchor. The deviation is volume-weighted and anchored to the same period as the VWAP it wraps — not a rolling standard deviation — which is the statistically consistent way to band a VWAP (the same math TradingView's built-in VWAP bands use). ±2σ is the classic stretched-price reference; the optional gradient fill keeps the zones readable without clutter.
Previous VWAP Close — the exact level where the Session (or Weekly) VWAP finished its previous period, drawn flat through the current one. The same idea as previous day high/low, but volume-based: yesterday's fair price is a natural magnet and reaction level for today. Few VWAP tools carry this level forward — it is the reason this suite exists.
🔶HOW IT IS CALCULATED
From each anchor the script accumulates three sums bar by bar: volume × price, volume, and volume × price². VWAP = Σ(volume × price) / Σ(volume). The band deviation comes from the volume-weighted variance Σ(volume × price²)/Σ(volume) − VWAP². At every period rollover the previous VWAP value is captured first, then the sums reset to zero. Values only update on confirmed data — there is no repainting logic anywhere in the script.
🔶ALERTS
Seven alert conditions: price crossing each of the three VWAPs, price touching the +2σ or −2σ band, and price crossing the previous Session or previous Week VWAP close.
🔶HOW TO USE
1. Pick your anchors — Session for intraday, add Weekly for swing context.
2. Choose which anchor carries the deviation bands (Bands Around).
3. Keep Previous Session VWAP on — reactions at yesterday's fair price are the cleanest thing this tool shows.
4. Set alerts on the crossings you actually trade around.
🔶SETTINGS
Source (price input, hlc3 default) · Anchors (Session / Weekly / Monthly, each with color) · Deviation Bands (anchor selector, ±1σ/±2σ/±3σ toggles, gradient fill) · Previous VWAP Close (Session / Weekly levels).
🔶HONEST LIMITATIONS
On CFDs and spot forex the data feed reports TICK volume (number of price updates), not true traded volume. VWAP built on tick volume is still the standard practice on those markets and tracks the real one closely on liquid symbols, but you should know what feeds the math. On symbols with no volume data at all the script deliberately shows nothing rather than fake a line. VWAP is a descriptive average, not a prediction — this tool draws levels, it does not generate signals.
