Oh, ok. Reading the trading manual, I didn't realize the MM's have to have a buy and sell in at all times of a stock they are making a market in. Left me wondering how you make money when you are buying and selling at the same time. I think I'm starting to get the picture now. Only managed to read about 20 of the few hundred pages in the manual. Guess I'm going to have to read the rest of it.
DVD, I read your post with great interest, and understand some of it, ty; but the "Fiction" comment eludes me, could we have one more tidbit in the way of explanation. tia
