Decoding Powerful F&O Market Signals: Will Nifty’s 24,800 Support Hold or Crack?

The F&O market signals on 18th June 2025 point to mounting caution as Nifty futures slipped 0.17% to 24,826.90, with spot closing just above the critical 24,800 mark and a shrinking premium of 14.85. Open interest fell sharply by 3.4%, signaling long unwinding, while the weekly Put-Call Ratio (OI) crashed to 0.624—its lowest in weeks—reflecting aggressive call writing at 24,800 and 25,000 strikes. Max pain for both weekly and monthly expiries is clustered at 24,800–24,900, underscoring the importance of this support zone. On the upside, resistance looms at 25,000–25,100, a failure to reclaim 25,000 could drag Nifty down to 24,700 or even 24,500 in the coming sessions.

BankNifty futures eked out a modest 0.21% gain to 55,899.00, but the Put-Call Ratio (OI) remains subdued at 0.730, and max pain is stuck at 56,000. This suggests that while some support is emerging, upside remains capped unless BankNifty can decisively clear the 56,000–56,200 zone. FINNIFTY and MIDCPNIFTY futures also closed in the red, with their PCRs slipping further, indicating persistent bearish undertones in financials and midcaps. SENSEX futures mirrored the broader market’s lethargy, with a PCR (OI) of just 0.644 and max pain at 81,500, highlighting a lack of conviction among bulls.

Conclusion: What the Future & Option Chain Analysis Tells Us

The 18th June F&O data underscores a market at a pivotal crossroads: Nifty’s 24,800–24,850 support zone (aligned with max pain and key moving averages) is under siege, and a sustained break below this level could trigger a slide toward 24,700–24,500. BankNifty’s 56,000 max pain and tepid PCR suggest that financials are struggling to lead a recovery, while persistent call writing at higher strikes caps upside potential. MIDCPNIFTY and FINNIFTY’s weakening PCRs and lackluster price action reinforce the need for caution in sectoral bets.

Traders should deploy hedged strategies—such as 24,800 puts or 25,000 straddles in Nifty—and closely monitor the 24,800–24,900 zone for directional cues. A decisive move above 25,000 could spark a relief rally toward 25,255(critical Fibonacci resistance), but failure to hold support may invite further selling pressure. As global cues and institutional flows remain volatile, aligning with these F&O market signals—PCR trends, max pain shifts, and open interest changes—will be crucial for navigating the next big move.
