Delta-neutral strangle
An intraday short strangle on NIFTY that tries to stay delta-neutral through the day. It sells the call and put nearest 30 delta each morning, and whenever the combined delta drifts outside a band it rolls the winning leg closer to the money to rebalance. A combined stop and target on the whole position, and a 15:11 exit, close the day.How it trades
Results
PRE-BUILT · DEFAULTSWhere it made and lost money
In this test, quiet sessions with a range under 0.75% made ₹74,073 over 108 trades with a 78% win rate: the strangle needed few rolls and decayed through the day. Choppy wide-range days lost ₹48,208 over 66 trades, as the index crossed the delta band one way and then the other, forcing rolls that moved a short closer to the money just before each reversal. Trend days lost ₹23,398 over 70. NIFTY weekly expiry days earned ₹24,711 over 51 trades, helped by the fastest time decay, while other days lost in total.
About this strategy
- At 09:22 every session, sell one lot each of the call and put closest to 0.30 delta on the nearest NIFTY expiry.
- Every minute, add up the position's delta per lot from both short legs.
- If net delta moves beyond ±0.15, buy back the profitable leg (the side the market moved away from) and sell a new one at the strike whose delta matches the other leg's, capped at 0.50 so it never crosses the other short.
- Allow at most four such rolls a day.
- Close everything if the combined loss reaches 30% of the morning credit, or if profit reaches 60% of it.
- Otherwise close all legs at 15:11.
Why traders use it
A short strangle makes money from time decay as long as the market does not move too far in one direction. Keeping the net delta close to zero aims to take direction out of the trade, so the position earns decay rather than betting on a move. Rolling the untested side toward the money collects fresh premium and re-centres the strangle around the new price, a technique many experienced option sellers use instead of simply stopping out.
The year in plain words
With default settings on NIFTY from 1 Oct 2025 to 30 Sep 2026, the strategy traded 246 days and won 55%, ending just ₹5,434 ahead before costs with a profit factor of 1.03. Most days, 145, ended at the 15:11 exit; 77 hit the combined stop and only 24 reached the 60% target. Wins averaged ₹1,358 against ₹1,630 for losses. Each roll adds two more orders, so costs weighed heavily: after ₹20 per order and bid-ask slippage the result was a ₹48,107 loss. December made ₹11,842, January lost ₹11,140.
What the settings do
Risks
- Rolling toward the money increases the premium at risk, and after several rolls the position can be close to a short straddle.
- Every adjustment pays brokerage and spread on two orders, which turned a small gross profit into a loss.
- On expiry day the nearest expiry has zero days left, so gamma is extreme and delta changes very fast.
- Short options need margin, and a sudden spike can reach the combined stop before any roll can help.
Who it suits
Option sellers who want to learn or test delta-based adjustments and can run them automatically, since the position is checked every minute. With costs included the default version lost money, so it suits those who will study the band and roll settings.
Questions traders ask
What is a delta-neutral short strangle?
It is a short call and short put whose deltas roughly cancel, so the position has little exposure to small moves in the index. When the market moves, the deltas change, and the trader adjusts the legs to bring the total back near zero.
Is the delta-neutral strangle profitable on NIFTY?
In this backtest from 1 Oct 2025 to 30 Sep 2026 it made ₹5,434 before costs but lost ₹48,107 after ₹20 per order and bid-ask slippage, with statutory charges extra. Frequent rolls made costs decisive. Past results do not guarantee future ones.
How does the adjustment work?
If NIFTY rises, the short call gains delta and the position turns short. The strategy buys back the put, which has lost value, and sells a new put closer to the money with a delta matching the call. That restores balance and collects extra premium.
Why is there a limit on adjustments?
On choppy days the market can cross the band repeatedly, and each roll costs two sets of brokerage and spread. Capping rolls at four a day limits that churn, at the cost of leaving the position unbalanced late in such days.
