Background backfill of historical charts

Question

With auto-backfill, switching symbols in the QuoteGrid with symbol-linked historical charts triggers a backfill.

 

When the selected symbol has not been used in a while, the amount of data requested can be substantial, which generates lag while the backfill takes place.

 

I am wondering if it is possible to backfill missing history for symbols in active QuoteGrid even when they are not selected. This would best be done during times when MT resource use is low.

 

If this were done, switching to a new symbol would instantly create the needed chart.

You can right click on a symbol and select backfill

You can select Backfill all

 

You can turn off auto backfill and just do backfill all when starting.

Backfill-all does the trick to speed transitions from one symbol to another. 

 

If you scheduled a backfill-all task it to be optionally done at startup (like Auto-Backup), that would be sweet.
