Quote from NY0BScalper:

I think you're off on everything.

Off the top of my head:
First is add, second is remove
Bats: +.0027/-.0028
BYX: 0/+.0003
EDGA:-.00025/+.00015
NQBX:-.0018/+.0014
EDGX: +.0026/-.003
NYSE: +.0015/-.0024
ARCA:+.0021/-.003
NSDQ:+.0023/-.003
NQPX:+.0024/-.0013
LAVA:+.0024/-.0025
NSX+.0026/-.003

Hidden liquidity has different rates (-$1/1k for EDGX, -$3/1k EDGA, +$1.0 to add for NSDQ, arca has normal rebate, NSX gives none)

I'm pretty sure all of these are correct....

Once in a while i refer to this list at lightspeed. I figure they keep it somewhat uptodate also..

Maybe they are not passing through all of it; cause i see that BATX on our list shows .0027 for adding liq; while the lightspeed one shows 0.0025. But what the hell.. close enough.
