Clarification/Follow-up by Bishop_Chuck on 02/13/05 11:40 am:
I will also note that the time of day a sale closes can mean alot. I have seen alot of computer equipment, be real slow untill the last hour of the sale. Then even in the last 10 minutes the bids will come in every minute or so.

I have lost some on the last minute of the sale.

I have found that the ones that close in the middle of the night, or during working hours, often trade slower at the end, those in the evening hours when more people are apt to be on computers, go faster.
No proof, just from what I have seen.
