Hi,

is there any way to get the P%F source?
I´d like to modify it to get a P&F chart that is based on recent volatility instead of points/percentages.

All Trending ChartStyles are proprietary, closed source.

Where is the recent volatility method discussed?

I just like to have recent ATR as a measure for box size instead of percent.
I think it is used here:

So, box size would change over time and fit to volatility. Would this be something you would be thinking about to integrate in the already available P&F implementation?

Sounds similar to Adaptive Renko.

Yes, similar logic would be good for renko and p&f charts.

Sure, we can consider adding that method, but it won't happen for some time, maybe later this year.

How realistic is this?

Realistic for doing it by the end of the year? It's hard to say. I start almost everyday with a plan of things I'd like to do, but I end up working on the things that pop up that need to be done sooner. This PnF modification would be at the end of the queue.

This lookout does not fit to my needs. So I will do it myself.
If only I would not have to start from scratch...

What I am trying to do first is to replicate a renko chart and modify it afterwards to make it atr based.
However I am having problems right in the beginning.

With this code I try to set the bar width.

CODE:

Then I render the bars with this one:

What I get is a chart that is missing the bars I set to zero. Good thus far. However, one the bar after thos bars DrawEllipse paints the chart for every bar that was set to zero, resulting in this:

Why is it painting these multiple ellipses?

double diff;

                closeY = chartPane.ConvertValueToY(base.Bars.Close[leftEdgeBar]);
                pen.Color = base.GetBarColor(leftEdgeBar);

It would really help if there were a open source of a trending chartstyle.

I fully understand. However, I hope that someone could provide his own code of a trending chart style that would give hints in the right direction.

one further question I need help with:

currently I draw four lines to paint the bricks of a renko chart to the chartpane. However, I´d like to replace this with Draw.Rectangle.
However, I seem to have a misunderstanding regarding the height parameter:

CODE:

The DrawLine code works fine. What am I doing wrong with DrawRectangle then?

I am pretty sure at this point in time that I am able to create this on my own. So, if I decide to provide this to the community there is no need for you to program this.
