NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 27/10/2025

Sharing is Supporting

Open Interest Volume Analysis

Combined open interest moved higher across all majors (NIFTY, BANKNIFTY, FINNIFTY, MIDCPNIFTY, SENSEX), indicating fresh long buildup in the market in today’s session—the tone is supportive for bulls with expiry week in play.​

Rollover jumped sharply in every segment, showing confidence among traders to carry forward positions to November contracts; momentum has shifted from caution to aggressive positioning.​

Elevated open interest and rising premiums in November futures (especially NIFTY, BANKNIFTY, FINNIFTY) reflect strong conviction in uptrend continuation and improves risk/reward for long bets into expiry.​

October futures across indices are experiencing short covering, which further supports the bullish undertone as sellers unwind and buyers take charge.​

“Open Interest Volume Analysis” now points to real money entering the market behind the up-move, with data signaling an inflection higher in overall sentiment.
