Combined premium trailing straddle
An intraday short straddle on NIFTY that manages both legs as one position. A single stop sits 5% above the combined premium collected; once the straddle decays 5%, the stop moves to cost and then trails 5% above the lowest combined value seen. After a stop, a new straddle can be sold once the ATM strike changes, up to three a 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 ₹61,500 over 238 straddles with a 61% win rate: the combined premium decayed, the stop moved to cost and the trail locked the gain. Choppy wide-range days lost ₹29,995 over 172 trades and trend days ₹12,536 over 182. With a stop only 5% above the credit, any meaningful swing ends the straddle, a new one is sold at the next strike, and on a choppy day that one is stopped as well. The strategy also did better with NIFTY above its 20-day average, making ₹25,847 over 285 trades, than below it.
About this strategy
- At 09:20, sell one lot each of the ATM call and ATM put of the nearest NIFTY weekly expiry.
- Set one stop on the combined premium of both legs, 5% above the credit received.
- When the combined premium falls 5% below the credit, move the stop to cost.
- From there, trail the stop 5% of the credit above the lowest combined premium reached; it only moves down.
- Any stop or trail exit closes both legs together.
- After an exit, wait until the ATM strike changes and sell a fresh ATM straddle, at most three per day and none after 14:30.
- Close whatever is still open at 15:15.
Why traders use it
Per-leg stops can leave a straddle half open and directional; a combined stop treats the call and put as one bet on a quiet market and exits only when the total goes against you. Trailing the combined premium aims to lock in decay as it builds rather than giving it back in an afternoon move. Re-entering after the strike shifts lets the trader re-centre the straddle on the new price instead of giving up for the day.
The year in plain words
With default settings on NIFTY from 1 Oct 2025 to 30 Sep 2026, the rules sold 597 straddles, about two to three a day, and won 49% of them for ₹21,084 before costs (profit factor 1.09). The 5% stops were hit 287 times and the trail closed 221 trades, so most straddles lasted only a short while. December made ₹14,673, March lost ₹10,339. The small average gain per trade could not cover trading costs: after ₹20 per order and bid-ask slippage on two legs each way, the result became a ₹56,635 loss.
What the settings do
Risks
- A 5% stop on an ATM straddle is within ordinary minute-to-minute noise, so stops are frequent and results depend heavily on fill quality.
- Up to three straddles a day multiplies brokerage and spread, which turned a small gross profit into a loss.
- The trail and the stop at cost exit at market, which can be worse than the stop level in fast moves.
- Short straddles need margin and face large losses on sudden one-way moves before the stop fills.
Who it suits
Traders who prefer managing a straddle as one position and can automate it, since exits come quickly and re-entries need fast execution. Those with low per-order costs and tight fills are least affected by the cost drag shown here.
Questions traders ask
What is a combined premium stop loss in a straddle?
Instead of a stop on each leg, the trader adds the call and put prices together and sets one stop on that total. Both legs close together when the sum rises past the stop, so the position never becomes a single naked option.
Is the combined premium trailing straddle profitable?
On NIFTY from 1 Oct 2025 to 30 Sep 2026 it made ₹21,084 before costs but lost ₹56,635 after ₹20 per order and bid-ask slippage, with statutory charges extra. Nearly 600 trades made costs decisive. Past results do not guarantee future ones.
How does the trailing stop work?
Once the combined premium has fallen 5% below the credit, the stop moves to the entry level. After that it follows the lowest combined premium seen, staying 5% of the credit above it, and never moves back up.
When does the strategy re-enter?
After a stop or trail exit it waits for NIFTY to move enough that the ATM strike changes, then sells a new straddle at the new strike. It sells at most three straddles a day and none after 14:30.
