New Forum Topic: Error Could not copy VS assembly to QS directory
Merlin wrote 4 days ago

Error Could not copy "obj\Debug\MyQSExtensions.dll" to "........\Program Files (x86)\Quantacula, LLC\Quantacula Studio\MyQSExtensions.dll". Exceeded retry count of 10. Failed. The file is locked by: "Quantacula (208160)".

Obviously the DLL is locked when QS is open. Is there no way to compile/deploy directly from VS to QS without closing/reopening QS?

New Forum Topic: Universe question and period problem
Findex wrote 1 day ago


When taking a web only license is it also possible to make an Europe universe? And when making the close period 20 it makes it 220. So close[20] is set to [220] and close[10] to close[110], so something doesn't work right.

Kind regards, Erik

I guess it must me that I am using the wrong condition? See my drag and drop example. And there are no historical trades. Also I realized that I can only upload JPG and not PNG?

New Forum Topic: Squished type/buried parameter boxes
gmorg wrote 2 days ago

Sorry for the persistence but had recently asked this v. basic question and post has gotten lost. On two different Win 10 machines, the script plus parameter boxes are in places squished/cut off, or, worse, completely covered over and thence unavailable (eg. timeframe box missing in "Model Settings'). Display is fine on other programs. Have tried all recent Versions Q143, 144 and 145. Am earnestly trying to fairly evaluate Q-Studio. Is there some global format setting, say, that I can't find? Thanks.
