I am using tiered commissions and I am currently under 300,000 shares for this month.
In the TWS execution report window I noticed this: BUY 82 shares @ 42.26, executed on AMEX for a commission of -$0.18.
I tried to work through this commission, assuming I added liquidity:
AMEX rebate = 82 * -0.0024 = -0.1968
IB Commission = 82 * 0.0035 = 0.2387 => 0.35 (min commission).
So even before adding in finra, pass-though etc. the commission is about $0.16.
So how did I end up with -$0.18? What am I missing?
