I am trying to fetch per minute data from Historical data endpoint for 30 instruments using 30 threads. Code is in Python. The issues I am facing is when I fire 30 threads each trying fetch data for different instrument, for some instruments (between 3 to 6) I am getting no data in return. However I for sure know that data exists. Is there any throttling applied on Historical API for client Apps? To confirm my doubt on throttling I reduced the number of parallel requests from 30 to 8 and now I successfully received data for all instruments. Any alternative to avoid this problem?
