Description

When backfilling minute bars for a symbol from Interactive Brokers, Multicharts requests one day at a time. This rapidly runs into a pacing violation from Interactive Brokers, as they have strict rate limits on how often you can request data from a single symbol.
There's no reason to be hitting these rate limits. IB's API lets you download more than a single day's worth of data at once. In other programs I've backfilled an entire half-year of minute bars in a single connection. If Multicharts would take bigger gulps of data per request, it would never hit a pacing violation in these circumstances.

Steps to reproduce this issue

Load a one-minute chart that stretches back one year for a new symbol for Interactive Brokers.

We have made all currently possible IB data feed improvements, however, due to IB API limitations and specifics, you will still run into pacing violation when a lot of historical data is requested.
