That is ABSOLUTE TRASH!
If you start the trades on the smart conservative path FIRST, and don't let them get into those bad habits to begin with, then there will be less pain for everyone involved! These firms are trying to instill BAD habits into newbie traders, by suggesting crap like 15 contracts on a futures contract like NQ or ES, without explaining how fucked up that idea is! NO! They should be teaching them PRM by allowing them only ONE contract, and allow them to actually make money for the firm!
I know that has been gone over already, the firms do not want profitable traders, they want sheep to keep paying them the monthly fee.
Because they are too lazy to help others make money with them, side-by-side. That is too much work. They find it easier to make money for themselves by having all of their clients fail over and over, and they reap the reset fees over and over, while the propfirm reps sit in their cubicles playing solitaire all day long.
