I've done literally 1000's of MKT orders near the close (not MOC). Today I sent an order to sell 1500 shares of HRS six seconds before the close. The specialist filled 600 shares, but not the rest. Aren't they obligated to fill an accepted market order??? This is the first time this has happened to me. I'm convinced the specialist forgot about my order by mistake. Why should I take the risk for their screw up? What the rule on this? Thanks...
Lehman say's they're going to talk to the specialist about it tomorrow AM.
