NANDR ORB + Order Block EA
A MetaTrader 5 Expert Advisor for scalping XAUUSD (Gold/USD) on M15 (also supports M5 and M1), combining two strategies:
- Opening Range Breakout (ORB) — tracks the high/low of the first 15 real minutes of each trading session and trades confirmed breakouts + retests
- Order Block Detection — identifies institutional order blocks using volume pivot analysis (LuxAlgo methodology) and uses them as trade confirmation and SL anchors
Strategy Logic
Opening Range Breakout
- At the start of each enabled session, accumulate the ORB High and ORB Low over the first 15 real-time minutes
- Detect a confirmed breakout using a strict N-bar filter (no false breaks)
- Wait for price to retest the broken ORB level
- Enter on the retest
Order Block Confirmation
- A volume pivot is identified where the bar at index
[length]has the highest volume in a symmetric window - Market structure determines direction: bullish OB if the pivot was a swing low, bearish OB if a swing high
- Bullish OB zone:
[low, hl2]of the pivot bar - Bearish OB zone:
[hl2, high]of the pivot bar - OBs are removed (mitigated) when price penetrates the zone
Entry is taken when the ORB retest aligns with a nearby Order Block (optional — configurable).
Timeframe Scaling
The ORB window is always 15 real minutes regardless of chart timeframe:
| Timeframe | ORB Bars | Breakout Confirm | OB Pivot Length |
|---|---|---|---|
| M15 (default) | 1 | 2 bars | 5 |
| M5 | 3 | 3 bars | 5 |
| M1 | 15 | 5 bars | 10 |
All values auto-configured by timeframe and individually overrideable via inputs.
