NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 18/06/2026

Open Interest Volume Analysis

Today’s Open Interest Volume Analysis indicates that the Indian equity derivatives market continues to maintain a constructive undertone despite a relatively subdued move in the benchmark indices.
NIFTY closed higher by 0.34%, while BANKNIFTY outperformed with a 0.66% gain, and the derivatives data suggests that market participants are gradually increasing their bullish exposure rather than chasing prices aggressively.
The combination of short covering in the near-month NIFTY futures, fresh long build-up in July futures, rising rollover participation, strengthening Put-Call Ratios and expanding futures premiums reflects improving confidence ahead of the monthly expiry.
This Open Interest Volume Analysis also highlights that buyers continue to dominate on declines, although heavy Call writing at higher strike prices is likely to restrict immediate upside, keeping the market within a well-defined trading range until a decisive breakout occurs.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us

Today’s Open Interest Volume Analysis clearly favours the bulls, but it is a controlled and disciplined bullish setup rather than an aggressive momentum-driven rally.
NIFTY witnessed combined futures short covering, while the July contract attracted fresh long positions, indicating that traders are rolling over their bullish expectations instead of merely covering existing shorts.
The steady increase in futures premiums across both June and July contracts further confirms that market participants are willing to pay higher prices for future exposure, which is generally considered a positive sign for trend continuation.
Weekly and monthly Put-Call Ratios moved higher, showing that Put writers remain confident about defending lower levels, while aggressive Put additions near 24100 strengthen immediate support for NIFTY.
At the same time, significant Call additions around 24500 in the weekly series and 25000 in the monthly series suggest that option writers still expect upside to remain gradual rather than explosive.
BANKNIFTY continues to display the strongest derivative structure among the major indices. Fresh long additions across combined, June and July futures, along with higher premiums and PCR above 1.10, indicate sustained institutional buying interest. However, simultaneous Call and Put additions at 58000 suggest that traders expect consolidation around current levels before the next directional move.
MIDCPNIFTY also maintained a positive derivative structure despite lower trading volumes. Strong fresh long additions in July futures and a healthy options positioning indicate that broader market participation remains supportive, although reduced volume suggests selective buying instead of broad-based risk-taking.
SENSEX derivatives presented a slightly different picture, where significant short covering supported prices, but the decline in weekly PCR and concentrated Call additions near 77500 imply that upside momentum may remain comparatively limited in the immediate term.
Overall, this Open Interest Volume Analysis suggests that the broader market structure remains bullish with improving rollover quality, strengthening futures premiums and supportive option positioning. Unless key support levels witness aggressive unwinding or fresh short build-up, the prevailing trend continues to favour a ‘buy-on-dips’ strategy rather than selling into strength.
Traders should closely monitor whether fresh long build-up continues in the July series. Sustained long additions accompanied by higher trading volumes would significantly improve the probability of NIFTY and BANKNIFTY extending their ongoing uptrend beyond the current resistance zones.
