Was plodding along at $200 on some impressive ineptness and then punked out on a good short round noonish and the next thing i know, i'm punching out a bottom for maximum loss on the long side when i wanted to be short the whole way? Is this type of retardation common? Needless to say, rough day. -$644
The pass throughs are the rebates that are given for providing liquidity to the market. They are given by the various ECNS, isld, brut, arca etc
Basically its $2 per thousand for providing liquidity and $3 to remove liquidity. So if my bid or offer gets lifted for a thousand shares i receive $2. If I lift someones bid or offer for a thousand shares I pay $3.
My rebates are the summation of my lifting and providing liquidity throughout the day. On this particluar day it was almost $500. Obviously this means that I provided more liquidity to the market then I took away.
You can also do a search on elitetrader and find multiple threads on liquidity and rebate trading.
