Halts are based on specific criteria and rules, they aren't arbitrarily imposed.

Well, we might want to consider changing the criteria a little bit. No?

I think that going up or down 10% (or more) in a span of 5 minutes is a pretty solid criteria for automatic halting, which is what it is today. If you have a better proposition for the halting criteria, please post it here.
