I think it shoudl go down to lowest bid before that GM bid though so for example:
u bid 2 dollars
I bid 4 dollars
u bid 6 dollars
I bid 8 dollars
u bid 10 dollars.
I then backout (which I dont really aprove of)
then the bid shoudl go back down to 2 dollars.
Also I think it should be case by case. If your looking for a 3B and you bid on FA for one but then make a trade with someone for a 3B you should beable to back out. Personally I wouldn't but I could see that situation happening.
