Due to a lot of good press here (superior option analytics, etc.), I opened a demo account at TOS 2 years ago. I have to sheepishly admit that I was overwhelmed and intimidated as I stumbled around blindly, getting nowhere. Quite frustrating! My intent was to use both, doing the bulk/even all of my trading on whichever one provided the best rates. I dunno, perhaps I no longer have the patience/stamina to stay up half the night trying to figure out what I already know how to do?Quote from deltahedge:
I wonder if that customer extensively used margin when trading? Given TOS's exorbitantly high margin rates relative to IB, I believe if you use margin quite a bit then you're better suited to choosing IB as a broker. That being said, I loaded the demo of IB's TWS and nearly tore my hair out. Their platform is extremely slow and complex as all hell. I tried to load an option montage displaying all strikes on the SPX and it took forever to do so whereas in TOS it loaded in a matter of seconds. Due to TOS's superior trading platform I don't mind paying their rates, but if IB could actually make a feature laden and faster trading platform I would switch in a heartbeat.
While IB's platform can be just as confusing (maybe they all are), when I started with it 10+ yrs ago, I had the benefit of a trading friend who had already been on it awhile. That's probably the difference.
