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 likeNSE:RELIANCE-EQ
,NSE:INFY-EQ
, etc., returnsLTP: 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
fromgenerate_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:
Whether the
v3/quotes
endpoint currently supports LTP fetch for F&O stocks individually?Are there any internal issues or known outages today affecting quote retrieval?
If the token has additional scopes or access rights needed for real-time data?
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.
