  • QStudio Q184 is released as we gear up for the beta release of Quantacula Studio Version 2! You'll be able to run QS versions 1 and 2 side by side, they will install into separate folders, but will share the same user data folder. The purpose of this Q184 release is to include some changes that were made due to Version 2 that impacts Version 1. So, although there are no major functionality updates, please install Q184 if you plan to also install Quantacula Studio Version 2.

About 4 times now, in both b12 and b14, the program has crashed when trying to save a universe where I tried to save some changes to the composition in the Config window. I haven't yet pinpointed the exact sequence to kill it, because sometimes I get my save done ok. but it's a lot of dying.

Addendum: i can edit symbols in the other little box at the bottom of the Universes sidebar without problems, so i'm just avoiding the Config box for my universes for now as a workaround.

Open any block model. Disable one of the blocks. Try to run a backtest. Death comes swiftly.

Is it possible to load more stocks in Qweb from Yahoo Finance data? Now it's possible to load US and German stocks, but other stocks aren't possible. Is this something that is easily added?

I am working on my first model. I have a WriteToDebugLog statement in the Model. When I backtest the Model I get all of my WriteToDebugLog output. When I run only a single chart I do not get any WriteToDebugLog output. What am I missing?
