The backend flow is:

1. The client sends a company symbol to POST /api/analyze.
2. getInstrumentId searches Upstox and selects the underlying instrument key and expiry.
3. getOptions retrieves the option chain for that underlying and expiry.
4. getAtmStrike identifies the strike closest to the underlying spot price.
5. Strategy calculators generate payoff tables for the available strategies.
6. The route returns strategy results, payoff tables, and instrument metadata as JSON.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Geist, a new font family for Vercel.

Deploy on Vercel

The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.

Account deletion (server)

DELETE /api/account removes the signed-in user's saved analyses. To also delete the Neon Auth login from the server, set NEON_API_KEY, NEON_PROJECT_ID and NEON_BRANCH_ID (the Neon admin API, DELETE /projects/{project_id}/branches/{branch_id}/auth/users/{id}). Without them the route still deletes the analyses and answers authUserDeleted: false; the mobile app then falls back to Neon Auth's own delete-user call.
