Frequently Asked Questions

Which OR period should I start with?

Start with 30-minute OR. It provides a good balance between signal frequency and reliability (62% WR). Once comfortable, you can try 15-min (more aggressive) or 60-min (more conservative).

Do I need special software for ORB?

No. Any charting platform that shows intraday data works. Mark the first 30-min high and low manually or use OR indicator if available. TradingView, MetaTrader, and most broker platforms support this.

What if both OR levels get hit quickly?

If both OR High and Low are hit within 30-45 minutes of OR ending, it's likely a range day. ORB won't work well. Either skip the day or consider the ORB Fade variation (trade against false breakout).

Should I hold ORB trades overnight?

No. ORB is an intraday strategy. The opening range is specific to today's session. Exit all positions by 3:45 PM. Overnight holds introduce gap risk that isn't part of the ORB edge.

Why do we wait for a candle close?

A wick above OR High could reverse before the candle closes, trapping you in a false breakout. Waiting for a candle CLOSE beyond the OR confirms that price has actually committed to that direction.

How do I identify trend days vs range days early?

Trend day signs: Narrow OR (< 50% avg), gap in direction of break, price doesn't come back to OR midpoint. Range day signs: Wide OR, both levels tested quickly, price oscillates around OR. By 11:00 AM, the character should be clear.

Should I use OR opposite side or midpoint for stop?

Opposite side: Wider stop, 52% WR, 2.2× R:R average. Midpoint: Tighter stop, 65% WR, 1.4× R:R. Choose based on preference: consistency (midpoint) or bigger winners (opposite side).

How do I combine ORB with gap analysis?

Gap continuation (gap up + break higher) has 72% WR - most reliable. Gap fade (gap up + break lower) is 58% WR - less reliable but viable. No gap trades are 60% WR. Use gap direction as secondary confirmation.

What volume ratio confirms a breakout?

Breakout bar volume should be at least 1.5× the average bar volume during the OR period. 2×+ is even better confirmation. Below 1.2× is a weak breakout with higher failure probability.

Why is narrow OR better?

Narrow OR indicates volatility compression - price is coiling. When it breaks, the move is often explosive. Narrow OR (< 50% average) shows 74% WR vs 48% for wide OR. It's a built-in volatility filter.

How do I implement ORB with retest entry?

Wait for breakout confirmation, then wait for price to pull back to the OR level (OR High for longs, OR Low for shorts). Enter on the retest hold. This gives better entry and tighter stop. 70% WR vs 62% standard, but may miss non-retest moves.

What is the optimal multi-timeframe ORB approach?

Use 60-min OR for directional bias (which way is the day leaning). Use 30-min OR for standard confirmation. Use 15-min OR for stop placement (tighter stops). Enter 15-min break in 60-min direction for highest probability.

How does sector/index ORB correlation work?

Use XJO (index) OR as confirmation for sector stocks. If XJO breaks above OR High, only take long ORB on BHP/RIO/etc. Index + stock aligned achieves 75% WR vs 62% for stock alone. Major stocks lead sectors.

What is the range expansion scoring system?

Score factors: NR7 yesterday (+2), ATR compression (+1), BB squeeze (+1), Inside day (+1), Narrow OR today (+2). Score 5+: Aggressive ORB. Score 3-4: Standard. Score 0-2: Cautious or skip. Quantifies expansion probability.

How do I automate ORB strategy?

Key components: 1) Auto-calculate OR at period end, 2) Monitor for close beyond OR with volume filter, 3) Apply time and size filters, 4) Calculate position size from risk parameters, 5) Set bracket orders for targets/stops. Python with real-time data works well.
