Two views every desk should look at before placing a trade — where is the rotation, and where is the unusual activity. The same approach we teach inside the Trading Arc community, distilled into a single screen.
A heatmap of all twelve NSE sectoral indices — colour-coded by today's percentage move. Click any tile to drill into its constituents.

A direction-neutral momentum & volatility intensity score. Stocks with a spike in volume and range relative to their 20-day baseline rise to the top — that's where institutional positioning typically shows up first.
relVol = today_volume / avg_volume_20d
relRange = (today_high − today_low) / today_close
relMove = |today_close − today_open| / today_open
relATR = today_TR / ATR_20
R_raw = relVol × relRange × (1 + relMove) × relATR
R_score = 100 × R_raw / max(R_raw across universe)Equal-weighted product, normalised 0–100. Direction-neutral on purpose — a stock down 3% on heavy turnover ranks as high as one up 3%.

Educational illustration only. The universe is a static slice of the NSE F&O list and prices are simulated random walks for demonstration of the methodology — not a live feed and not a basis for any trading decision.
Open Sector Scope first. Note the 2–3 sectors on either tail — those are where today's directional bias is concentrated.
