SessionVWAP + ORB

This TradingView Pine Script indicator combines two powerful intraday tools:

Multiple Rolling VWAPs: It plots up to four independent rolling (continuous) Volume Weighted Average Prices (VWAPs) with user-defined periods (e.g., 1-hour, 2-hour, 4-hour, daily). These are "anchored" to a customizable session start time and roll forward accurately without daily resets, providing dynamic fair-value benchmarks that react at different speeds (fastest/shortest on top).

Opening Range Breakout (ORB) Zones: It displays the high/low range (with optional background shading and lines) for major global trading sessions — Sydney, Tokyo, London, New York, and US RTH (Regular Trading Hours, starting at 9:30 ET) — over the first configurable minutes (default 30) after each session open, with history for several prior days.

The latest version adds full timezone flexibility (e.g., Chicago, New York, UTC, London, Tokyo, Sydney), automatically adjusting anchor times and session opens.

Use Case
This script is ideal for intraday and day traders (especially in stocks, futures, forex, or indices) seeking confluence between volume-based value areas and session momentum.

VWAP Component: Use the layered rolling VWAPs as dynamic support/resistance. Price above the fastest VWAPs suggests bullish bias; pullbacks to slower VWAPs offer mean-reversion entries. The multi-timeframe view helps gauge short-term vs. longer-term "fair value."

ORB Component: Trade breakouts from major session opening ranges — e.g., buy above the New York ORB high (red line) for momentum longs, or fade failures for reversals. Combine with VWAP (e.g., only take NY ORB longs if price is above session VWAP) for higher-probability filters.

Overall: Overlay on lower timeframes (1-15 min) to spot setups like ORB breakouts aligning with VWAP crosses, or use for risk management (stops beyond ORB extremes). The timezone support makes it versatile for global markets without manual adjustments.
