Midday trend-day option sell
This intraday strategy tries to identify a trend day by midday and profit from it by selling an option against the trend. Between 11:00 and 13:30, if NIFTY has already covered more than its average daily range and a 5-minute bar closes near the day's high above VWAP, it sells the ATM put; near the low below VWAP, it sells the ATM call. VWAP acts as the stop.How it trades

PRE-BUILT · DEFAULTSWhere it made and lost money
This strategy bets that a strong midday push will hold into the close, and the evidence shows it is right only when the day really is a trend day. The 33 trades on sessions that closed near their high or low made ₹45,444 with a 76% win rate, as the sold option lost value steadily while the index kept moving away. The 16 trades on choppy days, wide ranges that closed back in the middle, lost ₹40,058 and won only 12% of the time: the midday edge was the extreme of the day, the move reversed through VWAP, and the short option was stopped. Flat openings produced most of the profit, ₹21,768 over 40 trades.
About this strategy
- Before the open, work out the average daily range of the last five sessions and yesterday's R1 pivot level.
- Between 11:00 and 13:30, look at each 5-minute bar of the NIFTY future and require the day's range so far to exceed that average range.
- Bullish signal: the bar closes in the top 15% of the day's range and above VWAP, plus at least two of a close above R1, a gap-up open and a close well above VWAP. Sell the ATM weekly put two minutes later.
- Bearish signal: the bar closes in the bottom 15% of the range and below VWAP. Sell the ATM weekly call two minutes later.
- Exit if the index crosses back through the signal bar's VWAP, if a later bar gives back 70% of the day's move, or if the option loses ₹5,500 per lot.
- Otherwise close at 15:15; one trade per day.
Why traders use it
Trend days tend to keep going into the close, and a day that has already exceeded its usual range by midday is often one of them. Selling the option against the trend earns both from the index moving away and from time decay, rather than paying decay as an option buyer would. VWAP gives a natural line in the sand: if the price crosses back through it, the trend-day premise is broken and the trade ends.
The year in plain words
From 1 Oct 2025 to 30 Sep 2026 on NIFTY the rules found 56 midday signals, won 55% and made ₹6,043 before costs, a profit factor of 1.10. After ₹20 per order and bid-ask slippage ₹3,100 was left. Most trades, 39, ran to 15:15, eleven hit the VWAP stop, four exited on the give-back rule and two on the rupee loss limit. Average wins of about ₹2,180 were slightly smaller than average losses of about ₹2,460. Months alternated between small gains and losses, from a ₹6,584 loss in October 2025 to a ₹7,471 gain in September 2026.
What the settings do
Risks
- The sold option is naked, and a sharp reversal can lose up to the ₹5,500 per-lot limit or more in a fast market.
- The edge before costs was small; statutory charges were not included in the after-costs figure.
- Trend-day identification is only known in hindsight; many midday extremes reverse.
- Expiry-day trades, where ATM options move sharply, lost money in this test.
Who it suits
Experienced intraday option sellers with full margin who can monitor or automate VWAP-based exits through the afternoon and accept results that alternate month to month.
Questions traders ask
What is a trend day in trading?
A trend day is a session that moves steadily in one direction and closes near its high or low, often covering more than its usual daily range. Traders try to spot one early and trade with it, as the move tends to persist into the close.
Is midday trend-day option selling profitable?
In this NIFTY backtest from 1 Oct 2025 to 30 Sep 2026 it made ₹6,043 before costs and ₹3,100 after ₹20 per order and bid-ask slippage, over 56 trades. Statutory charges were excluded. Profits came from true trend days and were offset by choppy days; past results do not guarantee future ones.
Why sell an option instead of buying one?
Selling the put on an up-trend day earns from the index rising and from time decay, which is strong in the afternoon. A bought call would need the move to outrun its decay. The trade-off is a naked short with a larger possible loss.
Why is VWAP used as the stop?
On a trend day, price usually stays on one side of VWAP. If it crosses back through the VWAP level at the signal bar, the trend premise is in doubt, so the trade is closed.
