In what order are the studies being executed?

[Dennis]

It is currently unclear to me, in which order MotiveWave executes studies that I add to a plot.
It's not running them by alphabetical order or by the order I added them to my plot.

Does anyone know what the technical insights are and how I can control the execution order of studies?

I can't find anything in the MotiveWave SDK Javadoc.

I would assume there are running in parallel, Java threads.

cheers.

I answered with a suggestion that might shed light on this here

Sadly not. They are using the same Thread and are being executed one-by-one:

e.g.
Study A Precalculate
Study A Calculate
Study A Calculate
Study A Postcalculate
Study B Precalculate
Study B Calculate
Study B Calculate
Study B Postcalculate

I found out in which order MotiveWave executes the studies
They are being executed plot after plot (from top to bottom) and inside of each plot the studies are being executed from left to right.
Nothing is running in parallel/multithreaded (at least on my machine with my configuration, I didn‘t find any setting to change that) - they are being executed one by one in a synchronous matter and one study has to be completely finished until the next one can start.

Aha !!! Great research !
Care to explain how you came to this conclusion, @Dennis ?
Did you create a Study that sub-created 2 additional plots and wrote to debug in all three places or so ?

That will certainly offer us coders extra options in the future !!

Thanks a lot !😆

I added info-output-messages to the preCalculate method of each study and did a lot of try and error 😅

Ha ! Another excellent find !!
Glad to have you(r expertise) on this forum !
