Live Sync Engine & Status Pill
On every page load, the terminal fires an authenticated request to nseindia.com/api/fiidiiTradeReact via the allorigins.win CORS proxy.
LIVE SYNC — Today's session data was fetched successfully. Numbers update automatically.
LOCAL ARCHIVE — Markets are closed or NSE returned no new data. Dashboard uses the embedded 15-day history.
💡 Pro Tip: Hit Force Sync in the top-right to manually trigger a fresh data pull mid-session.
The animated dual-bar gauge in the Hero card plots the relative aggression of FII vs DII in absolute flow terms. It answers: "Who is driving the market today?"
FII BAR (RED)
Shows FII's share of total combined flow. A 70%+ reading = FIIs are the dominant force (selling or buying).
DII BAR (GREEN)
A wide DII bar means domestic funds are responding heavily — often absorbing FII sell-offs or co-buying in rallies.
💡 Reading Signal: FII Selling 80% + DII Buying 20% → Panic Sell with little DII support. FII Selling 80% + DII Buying 80% → Structural Rotation, not a free fall.
Tracks the number of consecutive trading sessions FII has remained on one side (All Buy or All Sell). Streaks are powerful market signals.
🔴 SELL STREAK: The longer the sell streak and higher the velocity, the more likely an oversold bounce. A 10+ day streak at ₹5,000+ Cr/day = historically extreme.
🟢 BUY STREAK: Sustained buying with high velocity is a strong confirmation of trend reversal or foreign re-entry into India.
The Streak Velocity shows the cumulative net flow (in ₹ Cr) during the streak — measuring the total damage or firepower.
Under the "Visual Flow Heatmaps" tab — GitHub-style density matrices for the last 45 trading sessions. At a glance, you can see entire patterns: months of selling, scattered buying, reversals.

DII Absorption
Days where DIIs bought more than ₹5,000 Cr — showing strong domestic conviction.
Extreme Divergence
FII sold ≥ ₹8,000 Cr AND DII bought ≥ ₹8,000 Cr — pure structural rotation days, rare and very significant.
