Build Q206 - Apr 30, 2020
  • QStudio Version 3 is here - 64-bit and .NET Core 3.1! This upgrade will run side by side with QSV2, and install in a separate folder, but uses the same data sources and models. In terms of extensions, you'll need to download the new extensions builds from the Extensions page to get them going in QSV3. The following extensions have been rolled directly into the core product so you won't see them on the Extensions page:
    • AplphaVantage
    • CryptoCompare
    • Morningstar
  • This version also fixes a bug in fundamental data that caused it not to load in new installs, and a bug in the FundamentalRatio indicator code-based constructor.
  • If you experience any hiccups during this transition phase please post them on our forum so we can address any migration issues, and enjoy the new 64-bit QSV3!
