Opening Range Breakout (ORB Strategy)
The ORB strategy defines support and resistance from the first 15 minutes of the market open, then trades confirmed breakouts with volume validation and fixed risk-reward targets. It is the flagship model of this hub and the highest-probability morning playbook for liquid index ETFs and large-cap stocks.
How the ORB Strategy Works
Between 9:30 and 9:45 AM ET, institutional and retail order flow collides at the opening bell. The ORB strategy captures the high and low of this window to form the Opening Range High (ORH) and Opening Range Low (ORL). When price closes beyond either boundary on above-average volume, it signals that one side has won the opening auction — creating a directional bias for the morning session.
Execution Rules
Wait for the 9:45 AM candle to close. Mark ORH and ORL from the 9:30–9:45 window on a 15-minute chart.
Switch to the 5-minute chart. Enter long on a candle close above ORH, or short on a close below ORL.
Confirm relative volume (RVOL) is at least 1.5x the average of opening-range candles. No volume, no trade.
Set stop at range midpoint (or opposite boundary). Project a 2:1 profit target. Exit by 11:00 AM if target is not reached.
ORB Strategy Settings
| Parameter | Standard Setting | Notes |
|---|---|---|
| Opening Range | 15 minutes (9:30–9:45) | Extend to 30 min on low-vol days |
| Chart Timeframe | 5m entry / 15m range | Never enter before range forms |
| Volume Filter | RVOL > 1.5x | Use 2x on QQQ / earnings days |
| Long Trigger | 5m close > ORH | Wick-only breaks are invalid |
| Short Trigger | 5m close < ORL | Confirm SPY/QQQ alignment |
| Stop Loss | Range midpoint (50%) | Or opposite boundary for wider stop |
| Profit Target | 2.0x risk (2R) | Positive expectancy at ~55% win rate |
| Time Stop | 11:00 AM ET | Morning momentum fades after this |
