Describe a trade
In plain words, to Claude or ChatGPT: “sell a NIFTY strangle every week, 1% out, but only when VIX is above 15.” The backtest comes back in seconds, with a report you can send to anyone.
Three questions, answered
What is it?
A backtester for Indian index options that you talk to. It plugs into Claude, ChatGPT or Gemini as a tool, so you describe a strategy in a sentence and get a costed, honest result back.
Do I need to code?
No. If you can type a message, you can use it. The chat app does the talking; Stratify does the arithmetic on real one-minute prices.
What does it cost?
Nothing. A full year of NIFTY weekly options, a hundred backtests an hour, every feature. There is no trial that expires.
What a conversation looks like
You, in Claude or ChatGPT
Sell a 20-delta NIFTY strangle three days out, but only when India VIX is above 15. Roll the tested side if it doubles, and stop the book after a 15% drawdown.What Stratify runs, on real prices
