So far, no changes that I see. It is more important, however, that you get your "slingshot" orders in quickly so that if they sweep the book, you'll get filled.
An immediate retracement order to participate with the Specialist if he makes a quick trade after the opening.
Perfect example this morning. HAL opened at 31.00, my computer put in a sell order for 25% of the shares at 31.06, the stock immediately printed 31.15, and he had to include my shares...then the stock went right back to 31.06-31.09 or so.
BTW, any new guys should go to the "How does "Market Open" affect your trading thread under "Trading" - Lescor did a great job of explaining the strategy, and I helped a bit.
