I just received verification on this. If you make an offer at BTCSportsmatch and there is a line change, your offer will stand at the new line.
I don't understand how neither you nor nscala1 are not disturbed by this.
If I understand correctly, if I want Lakers -1 and it goes to -2, someone can match me at the changed line of -2?
Or does it only mean that my offer stands if the line improves for me? E.g. I want Lakers -2, it changes to Lakers -1, and I get matched at the better line.
Likewise, if I want Lakers -2 -110, and it goes to -2 -120, someone can match me at the worse line (which I don't want)?
I must be misunderstanding something, as this would be a disaster and I can't imagine any exchange functioning in this manner and having customers.
