I modified the original "Weighted Volume" as I described before to
use "TrueRange" rather than "Range":
Vol = Vol + (Volume / Average(Volume, Length)) * (Close -
Close[1])/TrueRange;;
I then added a Reference line calculated as:
Ref = Ref + (Close - Close[1])/TrueRange;
I then subtracted the Reference line from the weighted volume to arrive
at a Normalized Weighted Volume:
NWV = Vol - Ref;
Attached are some pictures.
In the top subgraph of each, the Price is green, the Weighted Volume is
red, and the Reference is blue.
In the bottom subgraph of each, the Normalized Weighted Volume ("NWV")
is the black curve.
These are weekly bars for several stocks.
I found it interesting that the black curve for SPY (and QQQQ) move
down continuously. Can anyone suggest a reason why?
