ORB SESSIONS

## ORB SESSIONS — Multi-Session Opening Range Breakout + Retest Strategy

**ORB SESSIONS** is a multi-session Opening Range Breakout (ORB) strategy built for intraday trading across the **New York, Asia, and London** sessions, with optional overlays (PDH/PDL, session levels, FVGs) and an optional higher-timeframe bias dashboard. It is designed to standardize ORB execution with configurable **breakout vs retest** entry logic, **R-multiple targets**, optional **trailing-to-TP behavior**, and a **prop-firm “flat window”** to force risk compliance.

---

## Core concept

For each enabled session, the script:

1. Builds an **opening range** (high/low, optional midline) during a configurable ORB window.
2. Trades breakouts from that range using the selected **Entry Mode**:

* **Breakout**: enter on a confirmed close through the ORB boundary.
* **Retest Zone**: after breakout, wait for a wick back to the broken level.
* **Retest Midpoint**: after breakout, wait for a wick back to the ORB midpoint.
3. Manages risk via session-specific **Stop Loss methods** and up to **3 take-profits** expressed as **R:R multiples**.
4. Optionally uses a **trailing stop** mechanic that “arms” after price moves **N ticks beyond a TP**, then trails the stop to that TP level.
5. Optionally **re-arms** after a trade closes (with max trades/session, exit-type filter, direction filter, cooldown bars, and “bars inside ORB” requirements).

## What’s included

### Trading modules (per session)

* **Session 1: New York ORB** (enable, direction filter, ORB start/duration, session end, flatten at end, SL method, TP R:R and quantities).
* **Session 2: Asia ORB** (same structure).
* **Session 3: London ORB** (same structure).

### Filters & controls

* **Timezone selector** (all session times interpret in this timezone).
* **Day-of-week filter** (enable/disable specific weekdays).
* **Prop Firm Flat Window**: optionally flatten/block new entries during a specified time window.

### Visual overlays (optional)

* Historical ORB lines, optional midlines, labels.
* PDH/PDL, Asian/London/NY session overlays, and Fair Value Gaps (FVG) display.

## Recommended directions for use

1. **Apply to an intraday chart** (commonly 1m–15m).
2. Open **Settings → Global Settings**:

* Set **Timezone** to match your intended session definitions.
3. Open **Trade Settings (All Sessions)**:

* Choose **Entry Mode** (Breakout vs Retest Zone vs Retest Midpoint).
* Set **Contracts** and whether to show SL/TP visuals.
4. Configure each session you want to trade:

* Enable/disable sessions, choose direction (long/short/both), set ORB start + duration, and define session end/flatten behavior.
5. Configure exits:

* Pick an SL method (Midpoint / Opposite Side / Fixed Points) and set TP R:R levels and TP quantities per session.
6. Optional: turn on **Trailing Stop** and/or **Re-Arm**:

* Trailing: arms after N ticks beyond TP, then trails stop to TP.
* Re-arm: control max trades/session, cooldown bars, and re-arm conditions.

## Alerts (automation-ready)

This script is designed to run with **a single TradingView alert** that triggers only when the strategy actually fills orders.

**Create ONE alert** and set:

* **Condition**: this strategy
* **Trigger**: **Order fills only**
* **Message**: `{{strategy.order.alert_message}}`

The script attaches an order-specific alert payload at fill time (Buy/Sell/Exit), so your automation receives exactly what the strategy executed.

---

## Notes / expectations

* ORB behavior depends on how you define each session’s ORB window and the chart’s liquidity/volatility; optimize ORB duration + SL method + TP R:R per market.
* If you enable **Prop Firm Flat Window**, entries are blocked and positions can be forced flat during that period (use this to comply with rules).
