I want Upstox to:

  1. Automatically open the chart of :

    • The highest gainer,and

    • The highest loser,
      in real-time from a specific watchlist, index (like Nifty 50), or market.

  2. Continuously monitor in real-time, and:

    • Switch the chart if the highest gainer/loser changes,

    • So I can

    • always viewing the chart of the current top gainer or loser.

Searched here and there and got to know that there is an HFT endpoint we can use to reduce latency, but not sure if we can place multi order with the hft endpoint and if we can what url should we use https://api-hft.upstox.com/v2/order/multi/place does this url work ?

44

Hi @Sushma_50979572 Correct — HFT is applicable only for the Place, Modify, and Cancel Order APIs. The Place Multi Order API does not have an HFT endpoint.

I tried getting historical data but kept getting an error both with v2 and v3 apis. Can someone suggest if v3 is the correct api version to use for all api communications?
Historical candle data
Intraday candle data
Live feed to get alerts
Placing order

Hi @Shubham_51538267, Yes, V3 is the correct version for all the APIs you mentioned.

Please share the error message you’re receiving so we can look into it further.

Thanks

Sure, below are the errors when trying to get historical candle data and live market quotes.

Hi @Shubham_51538267, It seems the query parameter you’re using is incorrect. Please try the URL below — it should work. Thanks!

Thanks for the previous answers. I am facing a handshake error and issue in getting live data from websocket even when the connection is successful.

FYI I am trying to subscribe for Nifty 50 live data and below is the error I see:
