I'm a futures trader, and I'm training others to do the same. I want to give them the free SIM platforms if there are any. It doesn't matter if it is on the clock perfect timing with the real market. It does need to be real data though. As many of these sites and platform outlets as can be listed here to choose from would be greatly appreciated.
There are many platform for free SIM futures trading, only you have to choose the right platform according to your need.
TD Ameritrade offers paper trading on the think or swim platform. You have to sign up for an account, but dont have to fund it.
