OBV is permanently made available in the Link Library section on the left of the Agoracom page.

Here is a definition.  The bottom line is that, at these prices, investors are accumulating, and/or shorts are covering.

As you can see, OBV is very positive and has been for some time.

Personally, I was wondering whether to load up today myself, but there is a limit to how much I can hold!

enjoy the high OBV levels!
