ORB option buying
The opening range breakout (ORB) is a classic intraday setup: mark the high and low of the first 30 minutes and trade the first decisive break. This option-buying version adds a layer of filters. It skips event days, big gaps, unusual range widths, extreme VIX and expensive options, and then chooses the strike whose delta, implied volatility and time decay give the best modelled reward for the risk.How it trades
Results
PRE-BUILT · DEFAULTSWhere it made and lost money
Breakouts only pay when the day keeps going. On trend days, sessions that closed near their high or low, the strategy made ₹65,156 over 41 trades with a 73% win rate, as price ran to the target of one range width beyond the break. Quiet sessions with a range under 0.75% lost ₹85,648 over 61 trades, winning only 20%, because the break faded back to the range midpoint, the main stop. Choppy days lost ₹51,658 over 43. Entries with India VIX above 14.5 lost ₹56,608 over 44 trades, when options were dearer and breaks reversed more often. Figures are before costs.
About this strategy
- Mark the NIFTY futures high and low from 09:15 to 09:45.
- Skip the day if it is a listed event day, the opening gap exceeds 1%, the range is narrower than 0.25% or wider than 0.9% of price, India VIX is outside 10-24, or ATM implied volatility ranks above 80 for the year.
- Until 13:30, on 5-minute closes, a close more than 5 points above the range high signals a call; below the low signals a put. If the close is already 0.3% past the level, skip the day.
- Among strikes within six of ATM, keep those with delta between 0.45 and 0.72, reasonable IV and modest time decay, and buy the one with the best reward-to-risk, if at least 1.
- Exit if the future returns to the range midpoint, the premium falls 35%, or the future reaches one range width beyond the break.
- Once up by 35% of the premium, move the stop to breakeven and trail; close anything open at 15:15.
Why traders use it
The first half hour often sets the day's battle lines, and a clean break from it can start a trend. Buying options keeps risk to the premium, and the filters try to avoid the conditions where ORB traders get hurt: news days, huge gaps, ranges too tight to mean anything or too wide to leave room, and options so expensive or fast-decaying that even a correct call loses money. Choosing the strike by Greeks rather than habit is meant to get the best value for each move.
The year in plain words
With default settings on NIFTY from 1 Oct 2025 to 30 Sep 2026, the strategy traded 146 days and won 38%, losing ₹70,512 before costs and ₹81,760 after ₹20 per order and bid-ask slippage. The most common exit was the future falling back to the range midpoint (69 trades); 38 reached the target. Wins and losses were similar in size (₹2,776 and ₹2,511), so the low win rate decided the result. Only October was positive; May (₹24,808) and June (₹17,430) lost the most. The filters did not rescue the breakout in this period.
What the settings do
Risks
- Most breakouts in this test failed, so long losing runs are likely.
- The filters and strike model add complexity without having shown an edge in this period.
- Time decay and any fall in implied volatility work against bought options after a failed break.
- Event days must be listed by hand; a missing date can let a news-driven day through.
Who it suits
Intraday option buyers interested in opening range breakouts and Greeks-based strike selection who want to study why breakouts fail, rather than expecting the filters to remove losing days.
Questions traders ask
What is the opening range breakout strategy?
It uses the high and low of the first part of the session, here 09:15 to 09:45, as trigger levels. A move above the high is taken as bullish and below the low as bearish. Traders enter in the breakout direction with a stop back inside the range.
Is ORB option buying profitable on NIFTY?
Not in this test. From 1 Oct 2025 to 30 Sep 2026 the filtered 30-minute version lost ₹70,512 before costs and ₹81,760 after ₹20 per order and bid-ask slippage, over 146 trades. Past results do not guarantee future ones.
Which strike is best for ORB option buying?
This strategy does not fix a strike. It checks strikes near the money for delta between 0.45 and 0.72, reasonable IV and modest time decay, then buys the one with the best modelled reward-to-risk. That usually means near-the-money or slightly in-the-money options.
Why skip big gap days?
After a gap of more than 1%, much of the day's move may already have happened before the range forms. Breakouts on such days are often late, so the strategy sits them out.
