What the F&O Futures Heatmap Shows
One tile per future
Every stock and index with futures on NSE gets one tile. The colour shows how much the nearest-expiry future closed up or down in the session: deeper green for bigger gains, deeper red for bigger falls, grey for little change. Tiles are sorted from the strongest gain to the steepest fall.
The two numbers on each tile
The large figure is the price change of the nearest-expiry future. The small line underneath is the change in open interest across all expiries of that stock, followed by the build-up tag for the day.
Why OI is combined across expiries
Near the end of each month traders roll positions from the expiring contract into the next one. Looking at one contract alone would show a sharp fall in OI that is only a transfer. Adding all expiries together removes this rollover effect, so the OI change reflects positions genuinely opened or closed.
Reading Build-up Across the Market
Long build-up (LB)
Price up and OI up: new positions were added while the price rose. Many LB tiles on one day show fresh buying interest spreading across the market.
Short build-up (SB)
Price down and OI up: new positions were added while the price fell. A cluster of SB tiles shows fresh selling pressure.
Short covering (SC)
Price up and OI down: existing short positions were closed. The rise is driven by exits rather than new buyers.
Long unwinding (LU)
Price down and OI down: existing long positions were closed. The fall is driven by holders leaving rather than new sellers.
Market breadth at a glance
The counts at the top of the heatmap (advances, declines and each build-up type) summarise the whole F&O segment. A day where most stocks show long build-up is broad-based; a day where the index rises on short covering in a handful of heavyweights is narrower.
Using the Heatmap in Your Analysis
Filter by build-up
Use the Show buttons to isolate one build-up type. This is a quick way to list every stock where fresh long or short positions were created in the session.
Drill into a stock
Click any tile or table row to open that stock's futures build-up history and see whether today fits a longer pattern.
Sort the table
The table below the heatmap can be sorted by price change, OI change or turnover. Large OI changes with high turnover usually deserve more attention than small moves on thin volume.
Limitations
Build-up labels describe what happened to prices and positions, not who was buying or selling or why. Hedging, arbitrage and index rebalancing can all create OI changes that carry no directional view. This page uses NSE end-of-day data and does not reflect intraday moves.
Index Groups, Breadth and Sentiment
Index groups
The Type filter can show only the stock futures in NIFTY 50, Bank Nifty, Fin Nifty, Nifty Midcap Select or Nifty Next 50, using NSE's current index lists. The Index groups card compares how each group moved and built up positions in the session.
Biggest fresh positions
The five stocks with the largest OI increase on long build-up and on short build-up. "Strong" marks a price move of 2% or more with OI up 5% or more.
Breadth chart
NIFTY candles with EMA 20, 50, 100 and 200 on top. Below, advances minus declines among stock futures each session, its 20-session average, and long build-ups minus short build-ups.
Futures market sentiment
A score from −100 to +100: 50% breadth, 30% fresh positions (long build-ups against short build-ups) and 20% exits (short covering against long unwinding). It matched NIFTY's direction on the same day 82% of the time, but the next day only about half the time.
What the backtest found
On two years of NSE data, the build-up tag of a stock made no difference to its next 5 days against NIFTY. Strong short build-ups were followed by a 0.24% lag and strong long build-ups by a 0.11% lead, both small. Very one-sided sessions, when 90% of stocks moved the same way, were followed by a positive NIFTY week on average, but there were only 46 such days.
F&O Future Heatmap: Frequently Asked Questions
Does long build-up mean the stock will keep rising?
Not on its own. In our backtest from July 2024 to October 2026, stocks tagged long build-up did no better than the others over the next 5 days. The tag describes what happened in the session.
Which stocks are in each index group?
The groups follow NSE's published lists for NIFTY 50, Nifty Bank, Nifty Financial Services, Nifty Midcap Select and Nifty Next 50, refreshed about once a month. Only stocks with futures are shown.
How often is the futures heatmap updated?
Once per trading day, after NSE publishes the F&O bhavcopy in the evening. It usually refreshes by 9 PM IST. Use the Session selector to view earlier days.
Which contract is used for the price change?
The nearest-expiry future of each stock or index, compared with its own previous close.
Why does OI look different from other sites?
Many sites show OI of the near-month contract only. This page adds all expiries together so that monthly rollover is not mistaken for positions being closed.
What does a grey tile mean?
The future moved very little in the session, usually less than a few tenths of a percent.
Is long build-up a buy signal?
No. It only describes that prices rose while open interest increased. It is one input among many and does not predict what happens next.
Are index futures included?
Yes. Use the Type buttons to show stocks only, indices only, or both.
