Change of lot size informations

gully
Hi,

Today there was a change of lot size.Abruptly in the middle of the week. HindPetro in the middle of the week changed its lot size from 700 to 2100(due to share split!-Who cares!!). Now I know how to get this information from /instruments would give me this dump. What i donot know is when to call this API? Calling this once a day is too much of a labor. Is there any notification from Kite end(not necessarily KiteApi) where I would know in advance that some scrip has changed its metadata?

Thanks

    Hi @gully -- Lot size changes happen abruptly and we do not get any realtime notifications ourselves, even as brokers. We have to rely on ad-hoc PDF circulars published by the exchanges.

    Hence, the most authoritative way of getting these changes is relying on the exchange instrument masters (which is what you get from the /instruments) call. Ideally, you should do this once a day (automate it) before market opening.

    @Kailash thanks..i will automate it. One further question. The dump that we get from the /instruments is it updated by any system at the backend/exchange or after such a circular that lot size has changed someone manually updates the csv? What is the exact procedure happening beyond the APIs?

    The exchanges publish the master files every morning, which we source and combine into a unified format. It's basically a cron job, hence automated.
