### Comment:
Ok, I know I’m no expert but it made sense to me. What if he used a different broker? Would he have been able to scale linearly then? Using something other than robinhood?

### REPLY:
Basically the two reasons are Robinhood limits how many contracts you can sell at once and also times your orders to execute at suboptimal prices so they can make money off of it by selling your order to MMs
