hi,
i wanna know how much api will exhaust to get option chain data of crude or any instrument on real time updataion. does upstox have any option get live option data in single api call keep it it running.
You can use the websockets v3 for getting the option chain and its data.
APIs are for a one time request, whereas the sockets are for Continous updates/ticks.
There is no concept of API exhaust
