Every time this comes out,  why isn't the cheapest Interactive Broker (IB) not on there.    They are the cheapest for everyone by far but THEY are difficult to trade with (maybe too professional).   For example I trade for 4.99 at TD with 1$ per option contract (+the 4.99).   Also I got 15$ per assignment BUT they changed it back to 43 even though I trade more than ever.

I started to switch to IB which annoyingly charge different commissions but options commissions always 50-75% cheaper than TD and no assignment or ticket fee.
