I like to trade Credit Spreads and Iron Condors. I use TOS and am happy with their software, service, tech support and pretty much everything else. Except for the cost of executing a trade. I have been looking at Tasty Works. I opened an (unfunded) account and it looks like it is going to be usable. The best part is the commission structure. Much better than TOS and here is the part I like best....no commission to exit a trade! So if I put on an Iron Condor, closing it out before expiration costs me nothing. Am I understanding that correctly? Would there still be fees, just not "commissions"? So, the real question is this: what other trading firm does this? If there are any, I would like to know as I have not settled on a permanent broker yet, but need to soon.
