When the market opens, you have minutes to form a view. Most traders spend those minutes flipping between tabs, missing the sectors that are moving and the stocks that matter.
Watching individual tickers gives you fragments. You never see whether the move you are tracking is isolated or part of a sector-wide trend.
NSE has hundreds of F&O stocks. Scanning them one by one before market hours is simply not practical, and most traders give up and trade on instinct.
The market rarely moves as one block. Banking could be selling while IT is rallying. Without a sector-level view, this rotation is invisible until it is too late.
A 0.5% NIFTY gain could be driven by two large-caps dragging the index up while 80% of stocks are actually falling. Standard indices hide this reality.
By the time you piece together a directional view from scattered data, the opportunity has moved. First movers are the ones with structured context, not faster reflexes.
A market heatmap is a visual representation of the entire stock market where every instrument is shown as a colour-coded tile. The colour — green for gains, red for losses — and its intensity directly reflect the percentage move for that session, giving you a structured, at-a-glance view of market breadth.
Instead of reading numbers in a list, you read the market visually: deep green tiles are strong movers, pale green is mild, pale red is a modest dip, and deep red signals significant selling pressure. Arranged by sector, the heatmap reveals patterns — which segments are leading, which are lagging — that a traditional watchlist simply cannot show.
Explore More Market Analysis ToolsEach tile's shade reflects the magnitude of the move. A stock up 3% appears a different shade than one up 0.3% — the intensity is data, not decoration.
Stocks are grouped under their sectors — Banking, IT, Pharma, Metals, and more — so you can immediately see whether a move is sector-driven or stock-specific.
Count the green tiles vs the red tiles across the full heatmap and you have a real measure of market breadth — how many stocks are actually participating in a rally or decline.
The heatmap is your starting point, not your endpoint. Spot an interesting tile, click through, and open a full instrument-level analysis without leaving your workflow.
The Stolo market heatmap consolidates every NSE F&O stock and index into a single, live, sector-sorted visual — so you arrive at a market view in seconds, not minutes.
The default view loads the entire NSE F&O universe sorted by sector. You see NIFTY, BANKNIFTY, FINNIFTY, and MIDCPNIFTY as index tiles at the top, followed by every instrument in its sector block. The moment you open it, you know where the market stands.
When you spot a sector that looks interesting on the full view, apply the sector filter and the heatmap narrows to show only those stocks. Banking, IT, Pharma, Metals, Oil & Gas — filter by any of the 20+ sectors supported and get an undistracted view of every instrument within it.
NIFTY, BANKNIFTY, FINNIFTY, and MIDCPNIFTY sit as prominent tiles at the top of every heatmap view. Their colour and size immediately tell you the broad market direction before you process a single stock tile below. If BANKNIFTY is deep red while NIFTY is pale green, that divergence shapes your entire session view.
A colour scale legend displayed on-screen maps each shade to a specific percentage range — from deep red at significant losses through neutral to deep green at strong gains. This means you are never guessing. When a tile is a particular shade, you know whether the stock is up 0.5% or up 3%, without reading a number.
The heatmap is your entry point to deeper analysis, not a dead end. When a tile catches your attention — an outsized mover, an unusual pattern within a sector — you can navigate directly to that instrument's options chain, OI analysis, or price chart without losing your market-level context.
The heatmap communicates market conditions visually. Here are the four primary states a trader needs to recognise and act on.
When most tiles across multiple sectors are green with moderate-to-strong intensity, the rally is broad-based. This is a healthy market condition where institutional money is rotating across segments. Bullish setups carry a higher probability of follow-through in such sessions.
When the heatmap is predominantly deep red across Banking, IT, Metals, and other major sectors simultaneously, it signals a coordinated selloff — often driven by macro news, global cues, or FII exit. In these sessions, the risk of bottom-fishing is highest and caution takes priority over aggression.
When some sectors are strongly green while others are red, you are seeing sector rotation — capital moving out of one segment and into another. The heatmap identifies rotation in seconds: if Banking is deep red and IT is deep green, the smart money is repositioning. Trade the gaining sectors, not the ones giving up ground.
When nearly every tile is pale — small percentage moves in either direction — the market is in a consolidation or indecision phase. Volume is typically low and premiums deflate. These sessions are better suited for theta-based strategies than directional bets, and the heatmap makes this condition obvious before you place your first trade.
Professional traders do not open positions without a market view. The heatmap gives you that view in under sixty seconds — if you follow a consistent process every session.
Start 7-Day TrialUse pre-market or early session minutes — when the heatmap reflects global cues — to form your bias. The colour distribution before 9:30 AM often maps closely to how the session unfolds in the first hour. Starting with context is the single biggest edge most retail traders skip.
NIFTY, BANKNIFTY, FINNIFTY, and MIDCPNIFTY sit at the top of the heatmap. Check their colours and percentage values first. Divergence between NIFTY and BANKNIFTY — one green, one red — is a signal worth investigating before you look at individual stocks.
With the default view active, let your eye find the clusters: which sectors are uniformly green, which are uniformly red, which are mixed. A uniform sector colour is the heatmap telling you that the move is sector-driven, not just a single large-cap pulling the index.
Once you identify a promising sector, apply the sector filter to isolate it. Now you can see which specific stocks within that sector are leading the move and which are lagging — a key distinction for stock-specific trades within a sector trend.
Look for tiles with extreme intensity — dark green in a mixed sector, or dark red in an otherwise bullish sector. These outliers often represent stocks with a specific catalyst (results, news, block deal) and can present high-probability setups when the broader market context aligns.
Select your candidate stock tile and navigate to its options chain, OI buildup, or price chart on Stolo. By the time you reach the instrument analysis, you already have sector context, market breadth context, and index direction — which is three layers of information most traders never have simultaneously.
Both tools help you find opportunities, but they operate at fundamentally different levels of abstraction. Understanding when to use each one sharpens your process.
The heatmap shows you the entire market simultaneously in colour form. Its value is breadth and instant sector-level pattern recognition — you see everything before you focus on anything.
A screener filters stocks against specific criteria you define — OI buildup, volume surge, RSI range. Its value is precision: it finds candidates matching exact conditions, but requires you to already know what you are looking for.
The Stolo workflow: Start with the market heatmap to understand what sectors and conditions are active today — then use the screener to pinpoint the exact stocks worth trading within those conditions.
