Matchbook lines

[guitar711]

Quick question about Matchbook. I've been checking out the lines there and had a question about them. When there is a line posted as follows:

-150 $200

Obviously the price is -150, but what is the $200? Is that the max I can bet or the max that I can win (meaning I can put in up to $300)?

It means that you someone has made an offer on the other side and you can bet $200 at -150 to make a profit of 133.33 in this case.
