Quote from Don Bright:
Actually the logic of the whole thing is the major key, the rest is just fine tuning.
The Specialist receives orders all night long, marked "opening only" - so if he gets a surplus of buy orders, he must walk the price up to gather enough shares from his book to nearly fill the order...then he, himself, sells short into this excess buy order.. at the HIGHEST PRICE he can, to assure that he gets his short shares back....they've been making money on these gaps for centuries, why not join him? I started participating in the openings back in 1981, it's worked ever since.
However, no fills today..sitting in a Holiday Inn in the Gold Country of Calif, a little wide on my envelopes, no automated program...back at it tomorrow.
All the best,
Don
