Ah, then you would be looking for information regarding the Accumulation / Distribution.
I did a search through StockTradingToGo, and found two articles. This
first one, and then
this one. I wrote a couple of articles a while back on using Accumulation Distribution as a tool, and how to read it for possible bias. (
Part I, and
Part II) Something I didn't mention in those articles however, is that there is also a tool called "Williams Accumulation / Distribution" - created by Larry Williams that tries to look deeper and track the sum more accurately.
