ORB + Session VWAP Pro (London & NY) โ fixedORB + Session VWAP Pro (London & NY) โ Listing copy (EN)
What it is
A clean, non-repainting intraday tool that fuses the classic Opening Range Breakout (ORB) with a session-anchored VWAP filter for London and New York. It highlights only the higher-quality breakouts (above/below session VWAP), adds an optional retest confirmation, and scores each signal with an intuitive Confidence metric (0โ100).
Why it works
โข ORB provides the dayโs first actionable structure (range high/low).
โข Session VWAP filters โcheapโ breaks and favors flows aligned with session value.
โข Optional retest reduces first-tick whipsaws.
โข Confidence blends breakout depth (vs ATR), VWAP slope and band distance.
Key visuals
โข LDN/NY OR High/Low (line break style) + optional OR boxes.
โข Active Session VWAP (resets per signal window; falls back to daily VWAP outside).
โข Optional VWAP bands (stdev or %).
โข Session shading (London/NY windows).
โข Signal markers (LDN BUY/SELL, NY BUY/SELL) fired with cooldown.
Signals
โข London Long / Short: Break of LDN OR High/Low ยฑ ATR buffer, aligned with VWAP side.
โข NY Long / Short: Same logic during NY window.
โข Retest (optional): Requires a tag back to the OR level ยฑ tolerance before confirmation.
โข Confidence: 0โ100; gate via Min Confidence (default 55).
Inputs that matter
โข Open Range Length (min): Default 15.
โข London/NY times & timezones.
โข ATR buffer & retest tolerance.
โข Bands mode: Stdev (with lookback) or % (e.g., 1%).
โข Signal cooldown: Avoids clutter on fast moves.
Non-repaint policy
โข OR lines build within fixed time windows using the current barโs timestamp.
โข VWAP is cumulative within the session window; no lookahead.
โข All ta.crossover/ta.crossunder are precomputed every bar (no conditional execution).
โข Signals are based on live bar values, not future bars.

Quick start (examples)
1) EURUSD, London momentum
โข Chart: 5m or 15m.
โข OR: 15 min starting 08:00 Europe/London.
โข Signals: Use defaults; keep ATR buffer = 0.2 and Retest = ON, Min Confidence โฅ 55.
โข Play:
โข BUY when price breaks LDN OR High + buffer and stays above VWAP; retest confirms.
โข Trail behind VWAP or band #1; partials into band #2.
2) NAS100, New York breakout & run
โข Chart: 5m.
โข NY window: 09:30 America/New_York, OR = 15 min.
โข Retest OFF on high momentum days; Min Confidence โฅ 60.
โข Use band mode Stdev, bandLen=50, show ยฑ1/ยฑ2.
โข Momentum continuation: add on pullbacks that hold above VWAP after the breakout.
3) XAUUSD, London fake & VWAP fade
โข Chart: 5m.
โข Keep Retest ON; accept only shorts that break OR Low but retest fails back under VWAP.
โข Confidence gate โฅ 50 to allow more mean-reversion setups.

Pro tips
โข Adjust ATR buffer to the instrument: FX 0.15โ0.25, indices 0.20โ0.35, metals 0.20โ0.30.
โข Retest ON for choppy conditions; OFF for news momentum.
โข Use VWAP bands: take partials at ยฑ1; stretch targets at ยฑ2/ยฑ3.
โข Session timezones are explicit (London/New York). Ensure they match your instrumentโs behavior.
โข Pair with a higher-TF bias (e.g., 1H/4H trend) for directional filtering.

Known limits & notes
โข Designed for intraday. On 1D+ charts, session windows compress.
โข If your broker session differs from London/NY clocks on a holiday, adjust input times.
โข Session-anchored VWAP uses the scriptโs signal window, not exchange sessions, by design.
