Why Is Study Price/Overlay From Faster To Slower Chart So CPU Intensive?

This is something that's been present in SC for as long as I can remember.

Whenever a Study Price/Overlay from a faster chart is placed on a slower one, it pins at least one core and slows down everything in SC.

For example, using 1 minute and 5 minute charts. Overlay one or more studies from the one minute onto the 5 minute. CPU requirement goes way up.

If you do the reverse and overlay a 5 min on a 1 min, there is no impact at all.

Why is that?

There may not be many instances where you want to do this but there are a few - such as visual timing cues on execution charts.

We are quite sure this is not going to be usually reproducible or a typical occurrence:

There is something unusual going on in your particular case. Check the Window >> Message Log and see if there are any messages which are indicating a full recalculation of the destination chart.
