Four-day breakout option sell
This overnight option-selling trade looks for NIFTY breaking out of its previous four-day range late in the session. On an upside break it sells the ATM put, on a downside break the ATM call, each with a far out-of-the-money hedge. The trade is held to the same time next day, betting the breakout will hold and the sold option will decay.How it trades
Results
PRE-BUILT · DEFAULTSWhere it made and lost money
The result depended on whether the breakout kept going overnight. In this test, trades where NIFTY fell more than 1% while held made ₹41,366 over 15 trades, and those where it rose more than 1% made ₹15,952 over 9: the market carried on in the breakout's direction and the sold option expired away from the money. The 35 trades where NIFTY stayed within 1% lost ₹99,919 and won only 29%, because a modest pullback against the breakout is enough to push an at-the-money short option into a loss. Calm evenings with India VIX below 11.5 made ₹11,605 over 18 trades, while VIX above 14.5 lost ₹26,046 over 15.
About this strategy
- Each day at 15:25, take the highest high and lowest low of the near-month NIFTY future over the previous four completed sessions.
- If the future is trading above that high, sell the ATM put and buy a put 10 strikes lower as a hedge.
- If it is below that low, sell the ATM call and buy a call 10 strikes higher.
- Use the nearest weekly expiry, or the next one if today is expiry day; only one position at a time.
- Close both legs if the sold option's premium doubles from its entry price.
- Otherwise close both legs at 15:25 on the next session.
Why traders use it
A close beyond a several-day range is a common sign that a move has momentum behind it. Instead of buying an option and paying time decay, this approach sells the option on the opposite side, so it earns decay overnight as long as the market does not reverse sharply. The far hedge caps the worst case and lowers margin compared with a naked sale. Entering late in the day uses most of the session's information before committing.
The year in plain words
On NIFTY from 1 Oct 2025 to 30 Sep 2026 with default settings, the rules fired 61 times and won 49% of them, losing ₹39,042 before costs (profit factor 0.74). The loss pattern is the problem: average losses of ₹4,931 were larger than average wins of ₹3,794, and the win rate was too low to make up for it. Fifty trades ran to the next-day exit and 11 were stopped when the sold premium doubled. February and April lost over ₹42,000 between them; July to September were positive. After ₹20 per order and bid-ask slippage the loss was ₹47,417.
What the settings do
Risks
- The position is held overnight, so a gap against it is taken in full before any stop can act.
- An ATM short option moves almost one-for-one with the index once in the money, so losses build quickly until the hedge 10 strikes away starts to help.
- Losses were larger than wins on average, so the strategy needs a high win rate it did not reach here.
- Near weekly expiry the sold ATM option has high gamma, which magnifies an adverse move.
Who it suits
Traders interested in combining a simple breakout signal with option selling, who can hold hedged positions overnight and accept a 50-50 win rate where individual losses can exceed ₹14,000 on one lot.
Questions traders ask
What is the 4-day high low breakout option selling strategy?
If NIFTY trades above its highest level of the last four sessions near the close, the trader sells an ATM put; below the four-day low, an ATM call. A cheaper option further out is bought as a hedge, and the trade is closed at the same time the next day.
Is the 4-day breakout option selling strategy profitable?
Not in this backtest. On NIFTY from 1 Oct 2025 to 30 Sep 2026 it lost ₹39,042 before costs and ₹47,417 after ₹20 per order and bid-ask slippage, with statutory charges extra. Past results do not guarantee future ones.
Why sell an option instead of buying one on a breakout?
A bought option loses value overnight through time decay even if the market barely moves. Selling the opposite-side option earns that decay and also profits if the breakout continues. The trade-off is that a sharp reversal hurts more.
Is the 15:25 check time still right with the 15:40 close?
The default keeps 15:25 from the original rule, written when F&O closed at 15:30. Since the close moved to 15:40, testing a later time such as 15:35 shows whether using more of the session changes the result.
