First, I'd set leverage to 0.5 long and short, so you don't go over 1.0 (don't spend more money than you have in your account)

I think where the algo goes wrong is it makes a really rigid assumption about the market and market dynamics are always changing. Even if stocks mean revert weekly Monday-to-Monday for a while, that'd be really strange if they always did so consistently. For every simple rule that's easy to exploit you can betcha somebody is already exploiting it and has already arbitraged all the alpha out of it.

Tearsheets are a great way to evaluate an algo.

You've got a good structure on this algorithm. It's holding a constant leverage (which is good), it's carefully avoiding exposure to a single stock, things like that.

Unfortunately, the basic thesis doesn't look like it holds up. Take a look at our lectures, in particular the ones about long-short equity and factor analysis, and see if that sparks some ideas for you to find a different thesis to test.
