Breakeven-adjusted straddle
This positional strategy sells a delta-neutral at-the-money straddle on the NIFTY monthly expiry and manages it purely by its breakevens. Whenever the index crosses the upper or lower breakeven, it trades one more option at the same strike to push that breakeven back out. There is no stop loss; the position is closed two sessions before expiry.How it trades

PRE-BUILT · DEFAULTSWhere it made and lost money
With only 13 monthly cycles, every condition in this test has fewer than eight trades, so none can be judged firmly. The pattern is still clear. The five cycles in which NIFTY rose more than 1% while held all won, making ₹2,88,692 before costs: on a rally the adjustment buys calls, which caps the damage and lets the puts decay. The five cycles in which NIFTY fell more than 1% lost ₹1,48,544 between them, with only two winning, because on a fall the default adjustment sells more calls, which adds premium but does nothing to stop the short puts losing as the index keeps dropping.
About this strategy
- On the first session of each monthly cycle with at least 20 calendar days to expiry, at 09:30, find the ATM strike of that monthly NIFTY expiry.
- Sell two lots of the ATM put and enough lots of the ATM call to make the position delta-neutral (usually also two).
- Work out the breakevens from the strike and the net premium collected so far, and recompute them after every change.
- Every five minutes, compare the near future with the breakevens: above the upper one, buy one lot of the call at the same strike.
- Below the lower one, sell one more lot of the call at the same strike by default, or buy back one lot of the put in the alternative mode.
- Allow at most six adjustments a cycle and wait at least 30 minutes between them.
- Close everything at 15:15 two trading sessions before expiry; there is no stop or target.
Why traders use it
A monthly ATM straddle collects a large premium and earns from three weeks of time decay. Rather than using a stop that crystallises a loss, this approach treats a breakeven breach as a signal to rebalance: buying a call cuts the short-call exposure when the market rallies, and selling a call collects more premium to offset the puts when it falls. Keeping everything at one strike makes the position easy to track, which appeals to traders who prefer adjustment over exit.
The year in plain words
On NIFTY from 1 Oct 2025 to 30 Sep 2026 the strategy ran 13 monthly cycles, won 10 and made ₹3,35,876 before costs, a profit factor of 2.40. With so few trades, costs barely mattered: after ₹20 per order and bid-ask slippage it kept ₹3,26,125. The risk sat in one cycle. The March 2026 position lost ₹1,85,510, which was also the maximum drawdown, wiping out more than three average winning months. Twelve cycles closed at the pre-expiry exit and the last was still open when the data ended; June 2026 was the best month at ₹89,446. A two-lot straddle without a stop can swing by lakhs within one month.
What the settings do
Risks
- There is no stop loss, so a single trending month can lose more than several good months made.
- Selling extra calls on a fall adds premium but also adds short exposure if the market later rallies hard.
- The position is held overnight for about three weeks and is fully exposed to gaps.
- Two lots of an ATM monthly straddle need substantial margin, which can rise further in volatile weeks.
Who it suits
Experienced positional option sellers with the margin for a multi-lot monthly straddle, who prefer rule-based adjustments to stop losses and can tolerate a drawdown of nearly ₹2 lakh in a single cycle.
Questions traders ask
What is a breakeven adjustment in a short straddle?
A short straddle has two breakevens: the strike plus and minus the premium collected per unit. When the index crosses one, this strategy trades one more option at the same strike, which changes the net premium and the number of short options, pushing the breakeven further away.
Is the breakeven-adjusted straddle profitable?
In this backtest on NIFTY from 1 Oct 2025 to 30 Sep 2026 it made ₹3,35,876 before costs and ₹3,26,125 after ₹20 per order and bid-ask slippage, winning 10 of 13 monthly cycles. One cycle lost ₹1,85,510. Statutory charges are excluded and past results do not guarantee future ones.
Why sell a call when the market falls?
On a fall the short puts gain value and the position becomes long delta. Selling another call at the same strike collects more premium and adds short delta, offsetting part of that. The alternative mode buys back a put instead, which reduces risk more directly but costs money.
Why exit two sessions before expiry?
In the final days, ATM options have very high gamma, so small moves change the position's value sharply. Closing two trading sessions early avoids that stretch and, on stock options, avoids physical settlement.
