Backfill throttling is a
LIMITATION IMPLEMENTED BY INTERACTIVE BROKERS inside
TWS.
=======================================================================
Interactive Brokers allows the following MAXIMUM amount
of backfill:
Sixty 5-day segments per any 10 minutes
period.
If you download say 30 days for every symbol it equals SIX
5-day segments
per symbol, effectivelly leading to only 10 symbols (30days
each) during any 10 minute period.
If you reach the limit Interactive Brokers will send error 162
(MAXIMUM limit reached - Throttling),
until 10 minute segment passes without allowing any subsequent
backfill.
Only AFTER 10 minutes you will be allowed to backfill
again.
It is really NOT mine invention - it is Interactive Brokers
policy - please complain to them.
There are zillions of
