SPX TWAP EDGE [Team VICI]

Time-Weighted Average Price with Dynamic Deviation Bands — Built for SPX Traders

SPX has no tradeable volume, which means VWAP is unavailable. This indicator solves that problem by calculating TWAP (Time-Weighted Average Price) — the institutional benchmark used by professional desks when volume data doesn't exist. TWAP weights every price observation equally across time, giving you the true average price for any period.

This indicator plots Daily, Weekly, and Monthly TWAP lines simultaneously with configurable standard deviation bands, providing institutional-grade mean-reversion and trend context across three timeframes on a single chart.

HOW IT WORKS

1. TWAP Calculation — On each bar, the selected price source (hlc3, hl2, close, or ohlc4) is accumulated into running sums for Daily, Weekly, and Monthly periods. TWAP = Total Price Sum ÷ Number of Observations. Every bar is weighted equally — this is the key difference from VWAP.
2. Deviation Bands — Standard deviation is calculated using a single-pass variance formula: Variance = E[X²] - (E[X])². The bands plot at ±σ (configurable from 0.1σ to 5.0σ) above and below the TWAP line, showing you where price is statistically extended.
3. Dynamic Lower Timeframe Granularity — When your chart timeframe is higher than the calculation timeframe, the indicator automatically fetches finer-resolution data. For example, on a 1-hour chart, it calculates TWAP using 5-minute bar data — giving you 12x more price observations per hour for a smoother, more accurate TWAP. Auto mode selects the optimal granularity, or you can override manually.
4. Period Boundary Detection — At the start of each new day, week, or month, accumulators reset and the previous period's closing TWAP is captured as a reference level. This gives you both the developing TWAP and the prior period's final value.

KEY FEATURES

• Three Simultaneous Timeframes — Daily (blue), Weekly (orange), and Monthly (purple) TWAP lines with independent show/hide controls. See intraday, swing, and position context all at once.
• Standard Deviation Bands — ±σ bands with adjustable multiplier (0.1–5.0). Identify when price is statistically stretched from the mean. Band fill provides subtle visual context.
• Previous Period TWAP Levels — Yesterday's, last week's, and last month's closing TWAP drawn as reference lines. These act as support/resistance levels for mean-reversion setups.
• Right-Edge Price Labels — Current TWAP and band values displayed at the chart edge so you always know the exact levels without hovering.
• 12 Built-In Alert Conditions — Price crossing above/below each TWAP line and each band level for all three timeframes. Set alerts directly from the indicator.
• Auto Calculation Timeframe — Automatically selects the optimal lower timeframe for granularity: 1-min for intraday charts, 5-min for hourly, 30-min for daily. Manual override available.
• Full Visual Customization — Per-timeframe control over colors, line widths, and line styles (Solid, Step, Circles, Cross) for both TWAP lines and bands. Configurable info table size.

HOW TO USE IT

Mean Reversion
When price pushes to the upper or lower deviation band, it is statistically extended from the time-weighted average. Look for rejection candles or momentum divergence at band extremes for high-probability reversion entries back toward the TWAP line.

Trend Confirmation
Price holding above the Daily TWAP with the TWAP line rising confirms intraday bullish structure. When the Weekly TWAP also slopes upward and price remains above both, you have multi-timeframe trend alignment. The opposite applies for bearish structure.

Support & Resistance
The TWAP line itself acts as dynamic support/resistance. The previous period TWAP levels (yesterday's close TWAP, last week's close TWAP) serve as key reference points. Watch for price reactions at these levels — institutional algorithms frequently anchor to TWAP.

Band Width as Volatility Gauge
Narrow bands indicate low dispersion (consolidation). Expanding bands signal increasing volatility and trending conditions. Use band width to gauge whether the market is range-bound or breaking out.

Multi-Timeframe Confluence
When the Daily, Weekly, and Monthly TWAP lines converge to the same price zone, that area becomes a high-significance level. Confluence zones amplify the reliability of TWAP as support or resistance.

SETTINGS GUIDE

Calculation Settings

• Calculation Timeframe — Auto (recommended) or manual override (1m, 5m, 15m, 30m). Controls the granularity of price data feeding into the TWAP calculation.
• Price Source — hlc3 (Typical Price, recommended), hl2 (Median), close, or ohlc4 (Average). hlc3 is the standard institutional choice.
• Deviation Multiplier — Controls band width. 1.0 = one standard deviation. Increase for wider bands (fewer signals), decrease for tighter bands (more signals).
• Table Size — Adjust the info table readability: Tiny, Small, Normal, or Large.

Per-Timeframe Controls
Each timeframe (Daily, Weekly, Monthly) has independent toggles for the TWAP line, deviation bands, band fill, colors, line widths, and line styles. Turn off timeframes you don't need to reduce visual clutter.

ALERTS

12 alert conditions are available from the Create Alert dialog:

• Price Crosses Above/Below Daily TWAP
• Price Crosses Above/Below Daily ±σ Band
• Price Crosses Above/Below Weekly TWAP
• Price Crosses Above/Below Weekly ±σ Band
• Price Crosses Above/Below Monthly TWAP
• Price Crosses Above/Below Monthly ±σ Band

All alerts include the ticker symbol and price in the notification message.

INFO TABLE

The top-right info table displays:

• Calc TF — The timeframe used for calculation (e.g., "1 min (Auto)")
• Mode — "✓ Lower TF" (green) when fetching higher-granularity data, or "⊘ Native" (orange) when the chart matches the calc TF
• Dev — Current deviation multiplier (e.g., "1.0σ")

TECHNICAL NOTES

• Built on Pine Script v6 using request.security() for stable lower-timeframe data — no scroll instability
• Self-referencing series accumulation pattern ensures calculation consistency across all chart ranges
• Optimized for SPX but works on any symbol — particularly useful for indices and instruments without volume data
• TWAP is the institutional standard when VWAP is unavailable — used by professional trading desks and execution algorithms worldwide
