if you're thinking of going to ab watley, search on ET for watley threads... and go to yahoo msg boards (for ABWGE)... and then think long and hard about going there....
They got MOC, EOW, EOM, GTC, GTD, AON, DNR. Why would you need MOO, just put in a market order prior to the open.
here's the link to the watley yahoo message board. apparently, they haven't filed all sorts of necessary papers, and other bad things... messages.yahoo.com/?action=q&board=abwge
add to that all the mental pressure to keep volumes up, as if just trading, whether scratch or slight profit helps your personal cause. That way, they yield huge amounts per seat instead of whether or not your grub stake stays in the game through profits or scratch trades. this subtle psychological warfare against their own licensed traders is why most traders maintain an outside account, or just leave off these "leveraged operations", as they're known. I've seen traders at their desk, trade through Ameritrade (with all its excessive fees) and do better for the same positions, both during and pre/post market than their direct access platform for the prop shop we were at. Imagine that, trading through the retail basis achieve consistently better results than the prop shop DA software. Whew....
Market on Close End of Week End of Month Good Till Cancelled Good Till Date All or None Do Not Reduce if you're scalping, careful of using these "auto executables", they can be quite deadly to your financial health........
man that link stinks.... over 4,400 comments on those ........@#$%$#....... they ripped off the assets of Onsite Trading LLC, and others, and continue to do so through a whole host of names, and no one, SEC, NASD or FBI seem to be (publicly) doing anything... let's hope that their day will come, and soon....
