After two days of decent volumes we're back to same old same old....drims and drams so far today.  I could see a repeat of Monday happening, where sudden and heavy selling moves in to send the PPS down, I think that was simply a shake, and if it happens again I'll be of the same opinion unless there's some news out to drive it.  

On the other hand if volumes spike simply due to buyers storming in and bidding the PPS up, that would obviously be preferable.  

But if I perceive another shake, now I'm ready for it.  Monday I only was able to add 500, now I have more dry powder in reserve.
