Guys, I don't want to sidetrack the thread, but what exactly is Jigsaw and its competitors? Like, I'm used there being brokers, and you go through them to buy stocks, etc. Say IB, Ameritrade, etc. Is Jigsaw a competitor with them, or some software you use through them to make your trades, presumably improving the trade experience, execution time, etc.? Look hoping for a real general answer so I can look into it further.
Thanks!
