There are a lot of markets I want to be able to automatically arbitrage, but I don't know how. There are some bots that do this, but none (to my knowledge) are open-source.

This could be a feature on the Manifold website or an external open-source script.

If you implement this feature, leave a comment and I'll award you the bounty.
