I started off trading commodities in the early 90s then moved on to trading currencies around 2006 and about 2 1/2 years ago started trading stocks which seems to be a lot less stress money wise, except when I read some of these stock boards.
That being said, I understand exactly what you are saying about how MM work. Others may need a little time or to think about it over night to fully grasp it.
Just wanted to say thanks for informing the board on how it all works.
