Error creating async window. Windows error code 1158: The current process has used all of its system allowance of handles for Window Manager objects. | 2019-10-29 14:03:02.719
Unable to load data because there was an error creating the async callback window

Hi this is what I get if I try to keep many chartbooks open at once. Is there any way round this? Ram is only at ~15% usage, I have plenty of system resources left

You really need to use multiple Sierra Chart instances:
Using DTC Server for Data and Trading in Another Sierra Chart Instance

This is an operating system limitation. Not with Sierra Chart. The asynchronous callback window is only used temporarily in this case for data loading.

Ok thanks. How many charts does the O/S limit per per instance, as I have to plan ahead if I am going to utilise more instances.

I think it looks like in the range off 1000-1500 per instance?

We do not know. And there might be a registry setting for this.
