Yes, you need an fcm or ib. Easy enough to get (several forum sponsors) This thread is almost 2yrs old...but pretty sure this all was already addressed. And no, it wasn't not knowing the difference between a stop market and stop limit...
Well, than you need to go get the appropriate licensing and enough money to become a clearing House.....sorry bud, you're going to need a middle man
There are so many more knowledgeable people here regarding this, but I think y have it backwards. Rithmic provides the service of connecting you to exchanges, it's kind of a middle man between you and FCM. They also do the risk checks for FCM etc. There are people who connect directly to exchanges but you do need large account for that.
I have a small account and a trading strategy in Python. Can someone tell me what is the minimum structure I need to be able to day trade futures using an API (excluding Interactive B)? Do I need AMP? Rithmic? Both? None? (I think I can already get real time quotes from my inactive TDA account)
