Let me explain.......
If INCA is in the ADF and they are offering .65 on a stock, they will remain at .65 until someone crosses their book at .65 (assuming it is the best offer on the book). Assume that it is stil there and GSCO bids .70..... the BBO will .70/.65 .
But if TRAC is in SM and offering .65 and someone puts in a bid/buy at .70 on ATTN assuming they are also in SM..... Then the trade would auto-execute with price improvement of .65. Since TRAC is there first.... ATTN will pay the TRAC fee (Maybe ?).
Last example... IF GSCO is at .65 offer and you put .70 bid on INCA (assuming they are ADF) .... it will go to the INCA book first then post level II (also assuming that .70 is not crossed on the INCA book) .... hence crossing the market at .70/.65
It will be PENNIES FROM HEAVEN !!!!!!!!
