What VLN Catalyst is
Structured market intelligence for Indian index derivatives.
Price tells you where the market is. Open interest, implied volatility, breadth, institutional flows and the event calendar tell you why — and what the market is prepared for. VLN Catalyst puts those pieces side by side, so analysis is a single line of reasoning instead of a dozen browser tabs.
Who it is for
Active participants in NIFTY, BANKNIFTY, FINNIFTY and MIDCPNIFTY derivatives — traders and analysts who want to read market structure, not just price.
What it provides
A watchlist, a market-events calendar, seven analytics modules for options and market analysis, and a historical market replay for studying past sessions.
Why people use it
Clarity and context: consistent, restrained interfaces where every highlight means something, and the history to test an idea against what actually happened.
Watchlist
Everything you follow, in one precise view.
Build named lists and follow each instrument on a live card — with its chart, option chain and futures one click away. Scan the market in seconds, then drill in only where it matters.
- Multiple named, reorderable lists
- Live instrument cards with charting
- Option chain and futures drill-down
