The future chain table shows open interest (OI), volume, and price for each expiry contract. Watch for rising OI + rising price (long buildup) or rising OI + falling price (short buildup). Use the historical OI chart to spot sustained institutional accumulation or distribution over days.

Futures price includes carry cost (interest rate), expected dividends, and market sentiment. Spot is immediate delivery price. When futures trade above spot (premium), traders are bullish. When below spot (discount), bearish. Large premiums often signal strong long buildup; deep discounts suggest short buildup.

Future OI Chart: Tracks total open contracts over time. Rising OI = new positions opening (buildup). Falling OI = positions closing (unwinding or covering). Spot vs Future Chart: Compare spot and futures price to see premium/discount trends. Divergence between the two often signals institutional positioning shifts.

OI data may be unavailable on market holidays, low-liquidity days, or when contracts expire and new series begin. Charts show last available data or leave gaps. Focus on liquid near-month and next-month contracts for most reliable OI signals.

Use the expiry dropdown in each chart header. Select near-month for current series OI trends, next-month to track rollover buildup, or far-month for hedging activity. Compare OI across expiries to spot early rollovers (OI shifting from near to next-month before weekly or monthly expiry).
