A bit split and big increase in number of contracts is going to enhance my thinking about moving trading accounts to Tastyworks. They do $1 per contract on entry, $0 on exit, with a limit of $10 for each leg. So a 50 contract BPS will cost $20 in, $0 out, for the commission. Or in our new world order, and with a limit of 200 contracts per leg per ticket, a 500x BPS position will cost $60 in ($10 for each half of the spread, 3 transaction tickets) and $0 out (vs the $600 in (~$300 for each half of the spread) and $600 out unless the close of a short position is $0.65, in whch case that 1/2 of the exit is free. $60 vs $900 if I got all of my math right - that moves the needle for me.
