ohhh... well each side (bid and ask) is stacked with Market Makers. They all show at least a (5k) volume, but it could be much more...unfortunately. So once that stack has gone through with buying or selling, the PPS will tick up or down accordingly. So I am watching to see how deep the Ask and Bid levels are to determine whether or not if this stock will move before it actually does. Does that help?
