No question this is going to be a volume killer today.
It will be interesting to see how this plays out today.
If our volume stays this low, I would highly suggest that we all write to pinksheets to show them how this new rule has increased our "liquidity". It seems to me this would be a great example for them. Going from 175M traded the day befor the rule to what appears to be a few million traded today.
Let's watch and see what happens. Maybe things will be different by the end of the day as people get use to the fact that this is the way it is.
