Quote from danjos:
Interesting and insightfull insight . Thanks Dan and keafan and mschey.
Oftentimes, right after getting filled on long position, immediately the bid/ask become 10 *240 and our filled price is in between bid and ask. (short would be similar but opposite cases).
I understand that Don would immediately try to dump your positions. But I notice that sometimes the offer got taken.
Why would specialist shows this big imbalance in bid/ask size right after the first print? Is he allowed to make up this quotes? (for example so that he can buy more at lower prices)
Most "traders" read the bid/ask size completely wrong. Imagine a "live" broker, actually near the Specialist...with 20,000 shares to buy...he can either show 1,000, 5,000 or the whole 20,000... and will likely only show the whole thing if there is a likely seller to be had (either from the book or the other brokers, etc.).
If I'm long, and the market is holding it's own, then I prefer to see a 5 x 99 quote size, because the likelihood of a move upward is better most of the time.
Don
