History Payload Validator

Quick Start

• Check logs for /api/v1/history errors (400/404, missing fields, symbol not found).
• Verify payload has: symbol, exchange, interval (e.g., 1m/3m/5m/15m/30m/1h/4h/D), start_date, end_date (ISO), and any required resolution/from/to fields per endpoint variant.
• Confirm master contracts are present for the exchange/symbol before requesting history.
• Send a manual test call; only start strategies after it succeeds.

Required Fields Checklist

• symbol: Exact broker symbol (e.g., NIFTY, BANKNIFTY, or contract code).
• exchange: NSE, NFO, MCX, etc.
• interval: Use allowed values; avoid raw seconds unless API supports it.
• Date range: start_date and end_date in YYYY-MM-DD (or datetime ISO if needed).
• Optional legacy fields: include resolution, from, to if the endpoint expects TradingView-style params.

Master Contract Precheck

• Ensure master contracts exist for the exchange:
  • If missing: run the platform’s master contract download/refresh step.
  • Re-test history after refresh.
