Open Interest Volume Analysis

Welcome to today’s Open Interest Volume Analysis for 13 July 2026, where we decode what Futures and Options data is signaling for NIFTY, BANKNIFTY, MIDCPNIFTY, and SENSEX before the next trading session.

Monday’s session was largely range-bound, but the derivatives data tells a more interesting story than the price action. Across all three major indices, combined futures Open Interest declined while prices remained stable or edged higher, a classic sign of short covering rather than aggressive fresh buying.

In the NIFTY, both July and August futures witnessed Open Interest reduction, while the weekly Put-Call Ratio jumped sharply to 1.616, indicating that traders have added significant downside protection near current levels. However, the monthly PCR softened slightly, suggesting that traders remain cautious about chasing the market higher.

BANKNIFTY continues to display relatively stronger derivatives structure. While July futures also saw short covering, August futures attracted fresh long positions, indicating that positional traders are gradually shifting their bullish bets into the next series instead of adding aggressively in the current expiry.

MIDCPNIFTY also showed a similar transition, with heavy fresh long addition in August contracts despite profit booking in July futures. This suggests participants remain constructive on the medium-term trend even after the recent recovery.

Overall, today’s Open Interest Volume Analysis indicates that bears are reducing exposure while bulls are still adding positions selectively in the next expiry. The derivatives data points toward a market that is stabilizing after recent volatility, but a decisive breakout will still require fresh long build-up and stronger participation from buyers.

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

Today’s Open Interest Volume Analysis reflects a market where sentiment has improved, but conviction is still developing. The dominant futures activity across NIFTY, BANKNIFTY and MIDCPNIFTY was short covering, which generally supports prices but is weaker than genuine fresh long accumulation.

The options data provides an important clue. NIFTY’s weekly PCR surged sharply while Max Pain remains at 24,200, indicating that option writers expect the index to stay close to current levels. Strong Put additions around 24,000-24,200 have strengthened immediate support, while heavy Call writing near 24,500 continues to cap upside.

BANKNIFTY stands out as the strongest index in the derivatives space. Fresh long addition in August futures alongside improving PCR suggests institutional traders are gradually positioning for higher levels over the coming weeks. MIDCPNIFTY is also showing encouraging signs with aggressive rollover into August through fresh long positions, reinforcing positive medium-term sentiment.

SENSEX futures added fresh longs despite limited price movement, showing that institutional participation remains supportive, although the reduced futures premium indicates traders are still avoiding overly aggressive bullish bets.
Actionable View: As long as NIFTY sustains above the 24,000-24,200 support zone, the broader bias remains positive. A decisive move above 24,500 backed by fresh long Open Interest Volume Analysis would confirm renewed bullish momentum and could trigger the next leg of the rally.

On the downside, sustained unwinding of Put positions below 24,000 would be the first warning that bears are attempting to regain control. Until either level is decisively breached, expect consolidation with a mildly bullish bias while closely monitoring whether future sessions shift from short covering to genuine fresh long build-up, which would be the strongest confirmation of trend continuation.
