Does anyone have a link with recent statistics on the Nasdaq market share for ISLD/INCA, BRUT, ARCA, etc? I typically send my non-marketable orders to the ECN with the most market share, and currently send them to ISLD/INCA, although I have tested BRUT recently and found no reliability issues to date. If someone has an ECN market share link, I would sure appreciate it. Thanks, -Eric
Have your system folks set-up a program to measure acknowledgement times. This is what some sophisticated shops use to measure speed.
hmmm... Do you see problems with this on a daily basis, or a huge number of stuck orders once every few weeks? I have only been using BRUT for the past week, executing ~ 1000 orders and and cancelling another ~5k orders have not had a single stuck order. I have now switched back to ISLD for my orders simply due to their greater perceived liquidity. But, as to stuck orders, I didn't see any problems. -Eric
I've been trying out Brut the last few days also and haven't had any problems. Feels like i'm still using ARCA in fact. Listed mostly but some Naz.
Brut and Arca are both pretty good; but if I have to pick, I guess it would be Brut. Since the NYSE is planning to become more "electronic friendly" with the "Direct Plus" product; I wonder if this will create additional trading opportunities on the faster ECN's?
Having used both, mainly listed stocks I find both of them to be equally fine and awful at the same time. When ARCA is having issues BRUT seems to be king and vica-a-versa. The only real difference between the 2 is that ARCA isn't really an ecn but an exchange which gives them some advantages over their competitors. As for cost I'm not sure what other people are referring to as economical but the difference isn't that big of a deal, which one offers the best fill would be my choice.
From the Nasdaq, Just enter the stock symbol. Will give a report to show what MMs and ECNs are most active in a stock: http://www.nasdaqtrader.com/static/tdhome.stm Example report: http://www.nasdaqtrader.com/asp/tdr...th=1-1-2004&Quarter=10-1-2003&I2.x=40&I2.y=19 It does depend on the stock, for which ECN returns better fills.
