Improved Backtest List Interface, Significant Changes Coming

Today, we shipped a few small updates to the backtesting interface. The main changes we shipped today are:

  • The 'Algorithm | Backtest' toggle that took you between the IDE and backtest results page has now been replaced with a regular button.
  • Because of the changes to the toggle, the backtest results page and the 'All Backtests' page should both load faster.
  • The 'All Backtests' page has been redesigned to match the same visual style you see on the Algorithms page.

These changes are laying the groundwork for something much more exciting - we're redesigning the backtest feedback loop to make it much easier to write contest-qualified algorithms. For example, on the new backtest results page, you'll be able to see things like:

  • Plots of your sector and style exposures
  • Plots of your position concentration
  • How many of the contest criteria your backtest is passing
  • And a whole lot more!

We're aiming to release the new page to open beta soon, and we look forward to getting your feedback.

Sounds good. Meanwhile on a laptop here, vertical working space at a premium. And seeing more algo title would be nice to have

Also, didn’t know you could use an image in the forums. Cool!

Maybe not a common use-case, but I've recently noticed the inability to open up multiple backtests in different tabs. This was convenient when I wanted to stay on a certain page in All backtests, and still open a single backtest up to see what the performance looked like.

Hi Cheng, thanks for the feedback - the same issue applies for the "My Algorithms" page. We'll look into it.

When will the Beta be released?

Hi Abhijeet -

I'd be glad to provide some input, but I don't really understand the scope of your efforts here. I think that there are some fundamental architectural changes you could make, but it might require a re-thinking of the whole research notebook/IDE offline/online arrangement. What is the scope of this project?

@ Jean - on a more general note, I think you'd benefit from a more structured and systematic system for capturing and responding to user input for a given project with transparency. Doing it on the forum is far from ideal. Leveraging your Github instance would be one way to go, perhaps with integration into the forum. Presently, there is a unidirectional character to user feedback. You solicit it (Abhijeet's "we look forward to getting your feedback" above), but on the one hand, don't really get into the nitty-gritty of the project, and on the other hand, don't have an open tracker for user suggestions. It is hard to stay motivated as a user in the context of this one-way framework.
