Straddle VWAP cross
Many option sellers watch a 'straddle chart', the combined price of the ATM call and put, with VWAP drawn on it. This strategy trades that chart on NIFTY weeklies. When a 5-minute bar of the straddle premium closes below the premium's own VWAP, it sells the straddle; when a later bar closes back above VWAP, it buys it back. It can repeat up to three times a day, re-picking the ATM strike each time.How it trades

PRE-BUILT · DEFAULTSWhere it made and lost money
Selling only while the straddle premium is below its VWAP means the trade is on when premium is falling, which suits quiet markets. In this test quiet sessions made ₹86,358 over 264 trades, and NIFTY's weekly expiry days, Tuesdays, made ₹44,197 over 128 trades with a 45% win rate, as fast decay kept premium below VWAP. Trend days were also positive, ₹31,156 over 190 trades. Choppy days lost ₹46,007 over 184 trades with a 27% win rate: the premium kept crossing back and forth over its VWAP, so the strategy sold, was bought back a bar later at a loss, and repeated.
About this strategy
- Build the combined price of the ATM call and put on the nearest NIFTY weekly expiry, and a VWAP of that combined price from 09:15, weighting by the volume traded in each leg.
- At each 5-minute bar close from 09:20 to 15:00, check the straddle at the strike that is ATM at that moment.
- If the premium closes below its VWAP, sell one lot each of that call and put.
- Each leg has a stop 50% above its sale price. Once one leg is stopped, the other leg's stop moves to its entry price.
- Buy back whatever is open on the first later bar where the premium closes above VWAP, or at 15:15.
- Re-enter on the next close below VWAP at the new ATM strike, up to three trades a day. After a trade ended by stops, the premium must first close back above VWAP before the next sale.
Why traders use it
VWAP marks the average price paid during the day, so a straddle premium below its VWAP suggests sellers are in control and premium is decaying. Following that line gives an option seller a clear rule for when to be short and when to step aside, instead of holding a straddle through a rising-volatility spell. The straddle chart with VWAP is a widely used tool among Indian intraday option sellers.
The year in plain words
On NIFTY from 1 Oct 2025 to 30 Sep 2026, the strategy took 644 trades, about 54 a month, and won only 36% of them, yet made ₹69,397 before costs with a profit factor of 1.36. Wins averaged ₹1,114 against losses of ₹467: many small losses on quick VWAP reversals, fewer bigger gains. 521 trades ended on a close above VWAP, 102 at 15:15 and 21 on a stop at cost. February made ₹27,018 and July ₹17,212. With so many trades, costs dominate: after ₹20 per order and bid-ask slippage the result is a ₹11,074 loss.
What the settings do
Risks
- Trading up to three straddles a day makes costs decisive; the pre-cost profit became a loss after charges.
- The VWAP of a newly chosen strike starts from 09:15 and may rest on thin early trading.
- A gap or spike between bar closes can push a leg well past its 50% stop before it fills.
- Long losing streaks happen; the longest in this test was 18 trades in a row.
Who it suits
Active intraday option sellers who already use straddle charts, can execute or automate many trades a day, and pay low enough costs for small per-trade gains to matter.
Questions traders ask
What is a straddle chart?
It is a chart of the combined price of the ATM call and put. Because it rises with volatility and big moves and falls with time decay, option sellers use it to judge whether selling premium is working at that moment.
How is VWAP calculated on a straddle?
Each trade in the call or put is valued at the call price plus the latest put price, and weighted by the volume of that trade. Adding these up from 09:15 and dividing by total volume gives the straddle's volume-weighted average price for the day.
Is the straddle VWAP strategy profitable?
In this backtest on NIFTY from 1 Oct 2025 to 30 Sep 2026 it made ₹69,397 before costs but lost ₹11,074 after ₹20 per order and bid-ask slippage, with a ₹15,130 maximum drawdown before costs. Past results do not guarantee future results.
Why does a 36% win rate still make money before costs?
The VWAP exit cuts losers quickly, usually after one or two bars, while winners can run for hours as premium decays. Average wins were more than twice average losses, which outweighed the low hit rate before costs.
