I am looking for something to test my numbers against and what you describe is what I'm doing (see data in first post).  But it doesn't appear to be how BCW does it.  Since I don't know technical trading I'm trying to figure out what is going on.

Also the btc-e api has many issues that are complicating the calculations so I'm trying to see how pros like BCW handle the data.  It seems like the example I'm illustrating with the raw data vs. their charts shows that they are doing something that I don't understand or are getting data from somewhere other than the API.
