Hidden Orders on ECN's

Any ECN's besides INET that offer that feature?

 

Most ECN's do, it's more a question if your broker supports it on that ECN.

 

Hello,

do anybody know which hidden ECN's on NYSE now have a good liquidity. I used UBS and Millenium last two months, but now it takes too much time to get my limit order fulfilled.

 

Hidden doesn't mean reserve.
