Qcharts says 24 7/8. DTN says 24 1/8. Your source said 24 1/4.

Lets put ourselves in Gary's place. He get data from S&P Comstock, a big name in data. They send out bad data as all sources do. Now how would you grab this as an error? Sure 0 volume or a high of 34 1/4 can be caught, but these type errors or hard if not impossible to find.

Gary, originally used another data source but felt errors were so great and many that he would pay more and go to S&P, you can't win for losing. All data has errors, there are too many hands and humans involved. It has always been that way. The thing you want is a vendor that will fix errors when found. Someone thinks that it is impossible to have errors on a name stock like CPQ, why should it be different than the other 10,000+ stocks that they supply.

I don't like data errors, I feel safer with QP than other sources that I have known.
