Yeah, and if he purchased all in a single order, it only cost him $10 since Tastyworks caps commissions at $10 (plus some misc exchange fees), and is $0 to close the position.  
  
 Other brokers make you pay a ticket fee plus a per contract fee. Some people have negotiated to only the per contract fee without the ticket, but it's still not capped and not free to close. So a similar order could be at least $750+ at TD for example, and another $750+ to close it. $1500+ vs $10.

There are still FINRA fees per contract, I think 0.14 cents. This trade should of been about $150 in commissions, even on tasty works.
