HI Guys

Is there an API that i can use to get Open Interest and advance decline ratio information.

Thanks.

Hi @Praveen_Tyagi,

You can use getQuote()

Hi Sujith, Thanks for your help. But somehow i remember that this API can be used only for live quotes.

Can i use this for historical data as well i would need that data for back testing my algorithm? And also this gives us Open Interest but not the advance\decline ratio. I can built a function to calculate advance\decline ratio by calling quotes on all the EQ instruments, but that would be pretty costly and also network latency will kill the algo.

Is there a way you guys can provide that data as well?

Hi @Praveen_Tyagi,

I am afraid we cannot provide API for open interest because we don't store open interest.
AFAIK there is no open interest for Equity.

Thanks Sujith. What about advance\decline ratio?

Hi @Praveen_Tyagi,

You can calculate it using websocket only. Just use close and LTP of the scrips you want.
