Data feed
Running free on NSE's own chain feed — no key needed. Snapshots refresh about every 20 seconds and Greeks are derived from live prices. For tick-fast updates with exchange Greeks, paste your Upstox access token below (market data is free on Upstox). Get it at account.upstox.com → Developer → your app → Generate token. Note tokens expire at 3:30 AM daily — when one dies, generate a fresh token and reconnect. The token never leaves this browser.
Loading the free NSE chain below — picks, chain table and tracking unlock once the first snapshot arrives. Add your Upstox token above any time for the fast lane.

Start track freezes every strike's LTP, lots, and the model #1 prediction at this instant. Live P&L and actual #1 are scored only against that book — not the live rank list.
Model backtester
Replays real 1-minute history. Each trial freezes the option chain at an entry minute, gives the model the move spot actually made and how long it took, then checks the pick against every strike's real prints when spot got there — a HIT if it was the #1 P&L strike then or up to 2 min later. Compare models on identical trials.

Not run yet. Pick a model and a history range, then Run backtest. The first run downloads the option prints it needs (a month of NIFTY takes well under a minute); after that the same dates replay from this browser's cache.
