Vinny-
it does...the www.attain.com will now take you to Domestic securities web-site, which is the old All-Tech
I don't think anyone but those prop traders are using ATTN, and thats not much.
yeah...i haven't been trading in a few weeks...but I did see them pop up every once in a while...
I think you 'll be able to see their activity at www.nasdaqtrader.com
just go to the monthly report section and put in ATTN
i know at one point Attain was actually paying their prop traders to use their ecn...but few did because the liquidity sucked
