Hello all
Thanks to Clyde Lee and his precious contribution to the list(s), I take
the opportunity to offer a little bit. Enclosed you will find two
studies- variations based on Clyde's work, a picture of what they look
like and the code in text form should any of you would like to check for
yourselves.
Basically, it is Clyde's work with more bells and whistles; all
parametrical that allow us to choose how we want the info displayed.
It is about two studies. The first deals with Cumulative Volume (see
code below) and the other adds some filters to the way info is treated
and displayed. Those of you who have a more responsive and smoother
algorithm than T3Average (Mark Juric's Adaptive Average, for instance)
are encouraged to use it.
It took me some time to prepare it and I give it to you with all my
appreciation. I hope you welcome it.
Regards
Zarifis Dimitroulis

{Indicator: Bars-Price_Since_Pvt
Purpose: Display the number of bars and/or the price difference since the
last detected pivot using Swing_Lee_Simple.
Note that if both elements are to be plotted on the same graph
it will be necessary to use the ScalPric parameter
(which is a multiplier for the price difference computed)
to get the price range and bar range to be approximately the
same.
For the QQQ that value is around 20;

Comment: Zarifis Dimitroulis made a few changes-modifications to the
original code provided by Clyde Lee.
Namely, the Swing_Lee function changed to series to include
variable time length... FourPeriod and Hilbert come to mind.
Also, better graphics have been added to make look better.
However, should one prefer to revert back to the original
code, one must select KeepCode=True
else the detailed graphics and the auto adjust for ScalePric
take place.
