Please excuse my late answer... to all guys who wrote me PMs: thanks so much for it!!! Just noticed now that I am able to read them, gonna answer you soon!!! thansk so much, great forum here!!!
So: free and cheap ecn stuff:
EDGA, curretnly at 0.0007

Nasdaq OMX BX: 0.0005 rebate.

BYXONLY: 0.0003 I think.
CBSX: Think they have reabte too.
CSA/CSN/CSP/NYMP: you pay abou t ~ 0.0012
some others, also mm's like GETCO etc. there are also a lot of other sepcial routes, customized routes I mean like for ex. ROUC on Sterling and/or Laser I think. you also have darc pools etc.
So far I have only set-up EDGA at my desk... gonna hopefully change soon. EDGA is nice and liquid, don't know so much about the other ones in terms of liquidty. Any comments and experiences would be appreciated!!! Also it would be nice to mention the prop firms whcih are good in setting up customized routes etc. most of them have no damn idea about it.... My current desk is great because it gave me a very nice deal in terms of commission/clearing rate I mean. But in terms of routes it is bull***.
Kind regards

I'd recommend getting BYXONLY and NSDQBX, in case there isn't enough liquidity pn EDGA.
As far as why people use the more expensive exchanges to take liquidity, there are two types of situations:
A) Market Participant A takes liquidity from an expensive ECN such as NSDQ/ARCA/EDGX because the cheap/pay you to take ECNs are not present at the best available price, or it they are present, there aren't enough shares to fill the order. If the level is about to "roll over" (change, favorably), people will often take the last available shares and pay the $.003 for them; for example, the offer is .62 but its size is depleting rapidly, having been at 10,000 and now having 500 shares left. The cheap ECNs are gone, but paying $3/1000 to take the last 500 shares at.62 isn't the worst way to enter a trade ever; it's highly probable that bids will come to .62 and the next best offer .63 will be shown on the inside, vs a .62 bid.
B) Market Participant B takes liquidity from an expensive ECN even though there is cheap/free/rebate paying liquidity available at the same price for enough shares to fill all of B's order. The technical term for this is "throwing money in the garbage." Some people throw money in the garbage because the difference in ECN price to them is relatively negligible (or believed to be so). Other people are forced to route to a certain ECN, or have no ability whatsoever to choose how their order is order is routed: such people are forced to throw money in the garbage.
People like trader B are great to have in the market, because they behave inefficiently. If you get filled on EDGX when there's still EDGA at the same price, you were just given an arb-like fill, or a fill where you are instantly in the money. Of course, the price can blow right through you just as it can go in your direction, but being positioned to get good fills that exploit poor order execution can't hurt profitability.
