Hans, What do you mean? I trade 10-20,000 shares on ISLD all the time. It is possible that your firm has internal restrictions that prevent you from trading in excess of 10,000 shares.
Hans, I guess you aren't paying those obscene INCA surcharges. Why do you think your 10k would not be snapped up on ISLD or REDI or ARCA is there was a buyer? Are buyers snobs? Do institutions not have access to ISLD? Nah.
Sure instintutions do...ARCA sucks...no rebate...yeah and Inca retail is expensive...but think of it this way... bid and offer with INCA, ISLD is your 1st choice, then SOES is your 2nd...jus dont hit TRAC or LSPD through SOES....after that, INCA is way cheaper than hitting ATTN (I HATE ATTN!!) or BRUT....
I believe arca does pay a rebate - the firms just do not rebate it back to the traders. I find that INCA is a terrible ecn - just way to slow and not the most reliable in terms of quotes. And the nasd has absolutely nothing to do with any ownership of instinet. In fact, they do not like each very much.
I think it would be a great idea for this site to have a page with every firm and all their exact fees listed. That way traders could see who is charging what for what.
Looks like INCA is participating in Supermontage...http://www.instinet.com/productnews/supermontage.shtml
If ecn's don't participate in supermontage,where will their quotes be seen and will proactive ecn's still execute against them if they don't participate?I don't know why an ecn wouldn't participate,since supermontage would give their orders more exposure.
You don't need Supermontage to be proactive. A firm just needs the feed in their montage for their customers. I just don't like one place to do this and SM is muscling its way in here.
