Quote from ogarbitrage:
CL options (product code LC) are European if I remember correctly and typically traded electronically. American (LO) and Asian (AO) options are typically traded OTC via voice brokers or on the floor.
To move size, participants still need to go to the floor.
Quote from DeeDeeTwo:
oga implied LO options are not traded electronically, only pit...
With IB I only have access to CL options...
LO does not even come up in the IB Symbol Guide.
I don't care American/European...
But whether spread is $0.03 or $0.05 makes BIG difference...
I think most non-Pros completely underestimate the REAL COST of option spreads...
Only the Market Makers make money on options long term...
Regardless of what people claim.
