F&O Prediction for Tomorrow 18 May 2026: Nifty Options, Bank Nifty Expiry and Futures Outlook

The F&O prediction for tomorrow on 18 May 2026 carries three time-sensitive variables that make Monday’s derivatives session particularly important: the Bank Nifty weekly F&O expiry on Monday, the Nifty May monthly expiry on 26 May creating a live weekly setup, and the PCR recovering from the extreme low of 0.57 on 11 May toward the 0.85 to 0.90 zone by Friday’s close, signalling that the aggressive defensive put buying of the five-session sell off is being systematically unwound. This F&O prediction for tomorrow is based on Nifty 50‘s Friday close at 23,643.50, India VIX at approximately 17 to 18 and confirmed Bank Nifty resistance at the 54,400 to 54,600 zone per Bajaj Broking Research.

Ankit Jaiswal, Senior Research Analyst at Univest, and Kunal Singla, Associate Director at Univest, have prepared this F&O prediction for tomorrow by assessing Friday’s option chain data, the PCR trajectory, India VIX and the Max Pain for the Nifty May 2026 monthly series. Both analysts agree that the F&O prediction for tomorrow on Bank Nifty is the most event-dense on Monday given the weekly expiry, while the Nifty F&O prediction for tomorrow centers on the 23,500 to 24,000 range as the week’s expected expiry zone.

F&O Market Snapshot: Key Data for Tomorrow’s Prediction

Bank Nifty F&O Prediction for Tomorrow: Weekly Expiry on 18 May

Bank Nifty Spot: Approximately 54,000-54,400 zone (recovering)

Weekly Expiry: Monday 18 May 2026

Key OI Resistance: 54,500 CE and 55,000 CE

Key OI Support: 53,000 PE and 52,500 PE

Max Pain (Estimated): ~53,500-54,000

The Bank Nifty F&O prediction for tomorrow is the most immediately actionable component of tonight’s analysis because Monday 18 May is a Bank Nifty weekly expiry day. Ankit Jaiswal’s F&O prediction for tomorrow on Bank Nifty is that Monday’s session will see the index pulled toward the Max Pain level of approximately 53,500 to 54,000, the level at which maximum option contracts expire worthless and market makers face minimum payout pressure. If Bank Nifty opens above 54,400, Jaiswal anticipates significant call writing above 54,500 that will cap any further upside in the F&O prediction for tomorrow.

Kunal Singla’s F&O prediction for tomorrow on Bank Nifty weekly expiry notes that Monday mornings for Bank Nifty expiry are characterised by elevated implied volatility in the opening 30 to 45 minutes, followed by a sharp IV crush as the morning session progresses and the expiry approaches. This IV crush is a short options strategy opportunity: Singla’s F&O prediction for tomorrow favours selling Bank Nifty ATM straddles in the 10:00 AM to 10:30 AM window after the opening range establishes, with a stop loss if Bank Nifty moves more than 350 points from the strike in either direction.

Nifty 50 F&O Prediction for Tomorrow: Weekly and Monthly Setup

Nifty Spot: 23,643.50 (Friday close)

Nifty Monthly Expiry: Tuesday 26 May 2026 (10 days remaining)

Expected Range for Week: 23,200 to 24,000

Key Call OI Resistance: 24,000 CE (maximum call writing)

Key Put OI Support: 23,000 and 23,200 PE

The Nifty 50 component of the F&O prediction for tomorrow identifies a 23,200 to 24,000 range as the expected trading zone for the week ending with the 26 May monthly expiry. Ankit Jaiswal’s F&O prediction for tomorrow notes that 24,000 call strike has the highest call open interest, indicating that option writers expect the Nifty to stay below 24,000 through the May monthly expiry. The 23,000 to 23,200 put strikes have the highest put open interest, confirming these levels as the institutional support floor for the F&O prediction for tomorrow.

The PCR recovery from 0.57 to approximately 0.85 by Friday’s close is the single most important options sentiment signal in the F&O prediction for tomorrow. Jaiswal notes that a PCR below 0.75 signals extreme bearishness and a high probability of a short-covering bounce, which is exactly what occurred in the two-session Nifty recovery from 23,379.55 to 23,689.60. For the F&O prediction for tomorrow on the Nifty to turn outright bullish, the PCR needs to cross 1.0, confirming that put buyers are fully unwound and new long positions are entering the market.

India VIX: What It Means for F&O Prediction Tomorrow

India VIX at 17 to 18 is the most important position sizing input for the F&O prediction for tomorrow. A VIX of 17 to 18 means the market expects the Nifty 50 to move approximately 1.0 to 1.1 per cent per day on average, implying a daily Nifty move of 230 to 260 points at the 23,643 level. This elevated daily range expectation means that options strategies for the F&O prediction for tomorrow must account for wider swings than in the January to March 2026 low-VIX environment of 12 to 14.

Kunal Singla’s F&O prediction for tomorrow on VIX-adjusted positioning is to reduce F&O lot sizes to 50 to 60 per cent of normal across all strategies until VIX demonstrates a sustained decline below 15. For option sellers, elevated VIX above 17 is technically attractive because option premiums are inflated and time decay (theta) is higher in absolute rupee terms, but the risk of being caught in a sharp directional move is correspondingly higher in this F&O prediction for tomorrow environment.

F&O Strategies for Tomorrow 18 May 2026

Bank Nifty Expiry Strategy: ATM Short Straddle Post-Opening Range

The F&O prediction for tomorrow on Bank Nifty weekly expiry favours selling the ATM straddle (same strike call and put) at the 10:00 AM to 10:30 AM window after Monday’s opening range establishes. This strategy benefits from the IV crush that typically occurs after the first 45 minutes of Bank Nifty expiry day trading. Stop loss: if Bank Nifty moves 350 points above or below the sold strike, exit the straddle immediately. Maximum profit occurs when Bank Nifty closes within 200 points of the sold strike at Monday’s 3:30 PM close.

Nifty Weekly: Bull Call Spread for Cautiously Positive View

For traders aligned with the cautiously positive F&O prediction for tomorrow on the Nifty 50, a bull call spread: buying the 23,700 CE and selling the 24,000 CE for the nearest weekly expiry. This spread limits capital outlay while capping upside at the 24,000 resistance where call writing is heaviest. This spread strategy in the F&O prediction for tomorrow is suitable for traders who believe the Nifty will test 23,800 to 24,000 during the week but not convincingly break above 24,000.

Avoid Naked Long Options Given Elevated VIX

The F&O prediction for tomorrow explicitly cautions against buying naked options (single CE or PE without a hedge) in the elevated VIX of 17 to 18. At these implied volatility levels, option premiums are inflated and a move in the right direction but below the breakeven price still results in a loss due to IV compression (vega risk). The F&O prediction for tomorrow recommends defined-risk spread strategies over naked long options in the current environment.

Monitor 23,800 Nifty Close as the Week’s Direction Signal

Ankit Jaiswal’s F&O prediction for tomorrow is that the Nifty’s Monday closing price relative to 23,800 will determine the entire week’s options positioning strategy. A Nifty close above 23,800 on Monday confirms that put option unwinding is accelerating and call buying is returning to the market, making the bull call spread strategy the correct positioning for the remaining days of the May expiry series.
