ECNS doing more volume than NYSE?

Is it just me or are the ECNS executing much more of the volume or certain high volume nyse stocks? AMD was one obvious example. Much less liquidity on nyse. Does the new ECN rebate really have this much influence?

 

Yep, this has been a growing trend over the past I'd say 12 months.

 

I guess i'm just a bit behind the times

 

how many traders are executing most of there orders on arca? what %of your traders are you getting liquidity?
