When I have two charts open for the same instrument with different time intervals and am running a different study on each, both studies update when either chart updates - I am running different studies on an NQ 1 min and NQ 15 min. THe study on the NQ 15 min is updating every minute.

In general, studies are calculated at the "Chart Update Interval". Refer to the following: Working with ACSIL Arrays and Understanding Looping: When the Study Function is Called Therefore, the study will be called many times while a bar is being built, it has nothing to do with a specific bar. If these are custom studies, then you can control how often the study itself is calculated by returning when a set interval has not been met.

No. When I run a study on the 15 min NQ and that's the only chart I have open, it updates every 15 minutes. When I also have a 1 min chart open, it updates every minute. The study (when it is the only chart open) only gets called once a bar.

Then it is up to you to control how often it actually calculates. There are going to be multiple calls to the study while a bar is building based on the information we linked to in post #2. What you do with each call to the study is up to you. We have set this as Programming Help and it is not something we can help you with further, as we do not give Programming Help.
