NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 18/03/2026

Open Interest Volume Analysis

Today’s Open Interest Volume Analysis clearly reflects a broad-based short covering rally across indices, but the structure underneath is not as clean as it looks on price. NIFTY and SENSEX are seeing consistent unwinding of shorts with declining OI, while BANKNIFTY and MIDCAP are showing selective fresh long build-up, indicating sectoral divergence rather than a uniform bull trend.

The drop in combined futures OI (NIFTY -1.53%) along with price rise confirms short covering, not aggressive long addition, which means this move lacks strong positional conviction. Even volumes have cooled off, suggesting participation is not expanding, a key caution signal in any upmove.

Options data further complicates the picture—despite PCR improving above 1, heavy CALL writing at higher strikes (25000–26000) and clustered PUT writing near 23700–23800 indicate a range-bound expectation with upside supply zones intact.

In BANKNIFTY, the Open Interest Volume Analysis shows a more constructive setup with fresh longs in April, but immediate resistance near 55500–56000 remains active due to aggressive call additions. Meanwhile, MIDCAP strength looks strong on price, but low rollover (7%) and sharp OI spike raise sustainability concerns.

Overall, this Open Interest Volume Analysis suggests a market driven by short covering and selective optimism, not broad-based institutional accumulation, making it vulnerable to sudden reversals near resistance zones.

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

This Open Interest Volume Analysis suggests the market is currently in a relief rally phase rather than a confirmed bullish trend, with short covering dominating NIFTY and SENSEX, while BANKNIFTY and MIDCAP are attempting fresh long-driven breakouts.

However, multiple caution signals remain:

Declining volumes in NIFTY futures → weak follow-through risk

Heavy CALL writing at higher strikes → upside capped zones (25000 NIFTY / 55500–56000 BANKNIFTY)

Max Pain clustering below spot → mean reversion possibility

Premium contraction across futures → reduced bullish aggression

Actionable strategy based on this Open Interest Volume Analysis:

Avoid chasing highs in NIFTY; prefer buy-on-dips near 23700–23650 zone with strict risk control

Watch BANKNIFTY closely—sustained move above 55600 can trigger momentum longs, else expect sideways consolidation

MIDCAP traders should stay cautious—sharp OI build-up with low rollover can unwind quickly

Keep an eye on 23800–24000 zone in NIFTY—this is now a supply zone unless strong long OI addition comes in

Bottom line: trend is fragile. This is a trader’s market, not an investor’s breakout yet, and the next move will depend on whether fresh long addition replaces short covering in the coming sessions.
