Hello,
Greetings!
As per the details available on various chat here, I have understood following point and I would request you to kindly reconfirm ( or inform correct status) the followings:

  1. Max no of app per user=6
  2. Max no of web socket connection per app=3 or
    Max no of web socket connection per user=3
  3. Max no of stocks per web socket=100
    Hope to get quick revert

Hi @mailtoskt,

Yes, all these points are correct for v2. Please note, we have v3 too. Check this for more details:

Thanks for your prompt response. I have a followup query on V3.

  1. Connection- 1 connection per app-user combination is the Individual Limit - Does this mean that one user can have just one we socket connection or it is just only 1 connection per app, and we can have many app with connection subject to instrument limits ( point 2 below) and if so how, many app one user will be allowed.
  2. It states that if subscribe full,2000 instrument keys subscription ie the individual limit. Suppose I have 10 scripts, then can each script access 100 different stocks through individual web socket connection means 10 web socket connections in total
    Thanks

Hi @mailtoskt,

We are checking this and will get back to you soon on this. Thanks.

Hi @mailtoskt

For each application, you are allowed a single WebSocket connection. If you create two applications, you can generate two access tokens, enabling two separate WebSocket connections.

For the second point, I assume that by “scripts,” you are referring to ten different programs, each utilizing data for 100 different stocks, resulting in a total requirement of approximately 1,000 stocks. If you intend to run all scripts concurrently, establishing a new WebSocket connection for each program will not be feasible. Instead, I recommend using a shared WebSocket connection across all scripts, allowing each script to subscribe or unsubscribe as needed within that connection.

I hope this helps.
Thank you!

Thanks Ketan,
As we have one web socket per app restriction now in V3, can I add few more apps with dedicated websockets keeping total subscription at my account level as per the upper limit prescribed. Hope for a quick response on how many apps can I create.
Regards

@mailtoskt you can create up to 6 apps.

Thanks. It seems that one can have ONLY one web socket connection irrespective of no of apps one creates. I tried creating another app+web socket combination, but it is not allowing as throwing this exception “Handshake status 403 Forbidden”. Is it so?

@Ketan - It might have missed your attention. Any update on the above.

Hi @mailtoskt

This was a typo mistake in the documentation. Let me get that corrected.

We are looking to provide multiple connections through different apps, let me get back to you on this!
