symbol Quotes

I hope this message finds you well.

I am reaching out regarding a persistent issue I am facing with the FYERS v3 Data API (https://api.fyers.in/data-rest/v3/quotes) while building a live market scanner for F&O stocks.

❗Problem Summary:

  • Every API call to v3/quotes for NSE F&O symbols like NSE:RELIANCE-EQ, NSE:INFY-EQ, etc., returns LTP: None.

  • Response payload structure contains the keys but d[0].v.lp is either missing or null.

  • This happens even during live market hours, with a fresh valid access token (via auth_generate.py).

🛠️ Implementation Details:

  • We’re using Bearer Token Auth with valid access_token from generate_access_token.

  • All API headers and symbol formats are properly constructed (e.g. NSE:TCS-EQ, NSE:SBIN-EQ).

  • Delayed each request by 250ms to avoid rate limits.

  • Verified using Postman and still receiving responses with missing or null LTPs.

🔍 Debugging Steps Taken:

  • Verified correct API base URL and token validity.

  • Handled all exceptions and printed full response JSONs.

  • Tried reducing symbol batch size to a single symbol — same result.

  • Manually tested symbols using Postman and browser.

❓Request:

Could you kindly confirm:

  1. Whether the v3/quotes endpoint currently supports LTP fetch for F&O stocks individually?

  2. Are there any internal issues or known outages today affecting quote retrieval?

  3. If the token has additional scopes or access rights needed for real-time data?

  4. Is there an alternate recommended endpoint for batch quote fetch (like v2/quotes or WebSocket fallback)?

⚠️ Impact:

We are building an automated intraday scanner for trading signals based on real-time data. This issue is blocking all trade signal processing and preventing any use of FYERS data for live decision-making.

We would appreciate your urgent support on this matter.
