Do I need to call on_connect or on_tick in a loop to get streaming of data

Do I need to call on on_connect/on_tick/connect functions explicitly in a loop to get live streaming of stock data? Do they have any implicit loop?

trade_then

on_ticks is a callback. Kite server is throwing tick data to this function. you have to do nothing just listen to it from inside of it. just don't do anything while listening that would take time and block this function. pass the ticks received here, to something ( non-blocking buffer/thread whatever is the equivalent in python to that ). From that non-blocking buffer/thread pick the ticks for storage or charting or algo calculations.

Thanks for the reply. But when I ran this script, it just returned the ticker data once. Is it that, I am running it after market hours and it will not return until there is any change in the tick?

trade_then

yes that is exactly the cause. it is after market hours.
during market hours you will receive ticks as the change happens in the data of the
prescribed scrips. i.e change in LTP, etc...

Thanks

I appreciate your prompt reply. I will try it tomorrow morning.

The data is streaming. Thanks for your help. I am facing another problem. it shows the error if I store the data in the data frame.

If I change the last statement in the loop to below statement then it works fine
tick_df_all2=tick_df_all.append(tick_df_latest,ignore_index=True)

Therefore it is considered as resolved
