Community Algorithms Migrated to Quantopian 2

Q Updates

Yesterday we launched Quantopian 2 which involved some changes to the API. In order to help with the process of migrating algorithms to the new API, we created the migration guide. In addition, we migrated several dozen popular community algorithms. If you click the clone button on the shared backtest, you are instead given the Quantopian 2 version. You can also inspect the code without cloning it by clicking the "Migrated Source Code" tab.

-- EDIT (original post only had 7 algorithms listed) --

Here is the complete list:

"In addition, we migrated several dozen popular community algorithms. "

Great!
You listed 7 of them, but where can I find the rest of the several dozen.

Thanks

Hi Steve,

The samples in the help documentation were also migrated so you can have a look at those as well.

NOTE: The complete list of community algos was originally a part of this comment, but was moved up to the original post.

Great, thanks for this! Quite helpful!

I was working with the "Simple Downside Protection Model" algo and the new version wasn't working on longer timelines, but it looks like I was able to improve it with a couple of data.can_trade lines (lines 47 and 54).

Hey Brad, it looks like a unicorn ! Great results.

The downfall (if not mistaken) is that it o transaction every days, You'd better set some fees and slippage.
