I recently came across a service that does this tracking and will automatically make the same trades for you. I'd be curious to see how well something like that would do in the long term.

Probably not very well because the reporting is significantly delayed and politions swing trade often.

This is probably a pretty bad idea to let loose wkth your bank account

How soon after a trade is made does it get reported?
