Shadows created by DrawRegion

[NinjaTrader_Bertrand]

Harry, looking at your code this issue seems to be related to pivots plot value being reset on the first bar of the session, hence the DrawRegion would have the Close price value at this point, this is what you see visualized.

[Harry]

That is correct. How can I draw regions that look correct then?

If I reset -> does not work
If I set to zero -> does not work, the speech balloon will point to zero

So whatever I do, no correct region is drawn between two horizontal lines or even other data series, if these are session related. Reset() should do the trick and tell DrawRegion() not to draw.

[Harry]

Have now replaced DrawRegion() with DrawRectangle(). The latter method plots properly, as opposed to DrawRegion(). With ZOrder set to -1, rectangles plot nicely behind price.

Great idea, Reset would only apply to the plot for visualization purposes. I believe as workaround a unique DrawRegion for each day would help.

New problem:

Indicator plots text via customized plot and draws a rectangle. How can I convince the indicator not to plot the filled rectangle on top of the text?

[Harry]

There seems to be a bug in DrawRectangle() as it draws over the right margin of the chart.

DrawRegion() does not draw over the right margin, but has the Baloo look.

So both have bugs. See chart attached.

I had used unique DrawRegions for each day (different tags), did not help at all.

Decoration

And by the way there are other DrawMethods that draw nice and useless pictures on the right margin....

See chart below.

Further strange finding

Further finding:

DrawRegion plots behind the lines and text, Draw Rectangle plots above the lines and text. Why is that?

[Harry]

Had to go back to the Baloo - Speech Balloon look of DrawRegion().

Reason: DrawRectangle() covers recklessly all bars and lines, where as DrawRegion() stays politely behind.

I would like to know why all of these Draw Functions are coded in a different way. There seems to be no logic behind the design, but they just seem to work at random. Some draw behind other indicators, other above. Some react to the initialization with ZOrder = -1, others don't. Some draw on the right margin of the chart, some don't.

Does this follow any concept?

[Harry]

Only solution might be to write two indicators.

Indicator 1 plots the lines and the text.

Indicator 2 plots the filled ranges by using DrawRectangle() and by referencing indicator 1. The second indicator would be initialized with ZOrder = -1, so the rectangles will hopefully plot behind the rest of the chart.

Just would need to reference a BoolSeries ("plot" or "do not plot"), two DataSeries containing the upper and lower range and one DataSeries containing the sessionCount to create the tags.

Would this work?

[NinjaTrader_Bertrand]

Harry, sorry for my late reply - I'll check into the default ZOrders assigned in our Draw methods.

Yes, the 2 indicators should do it, ZOrder -1 worked well in my test to default the DrawRectangle behind the price bars.

[Harry]

I coded a second indicator now. I can handle the drawing problem with this. The separate indicator catches the DataSeries from the other indicators, calculates the rectangles and plots them behind price and the lines of the other indicators.

However there is a new problem, now. If I call the pivots indicator in DailyBars mode, it does not work. For example

double mainpivot = 0; 
mainpivot = Pivots(PivotRange.Daily,HLCCalculationMode.DailyBars,0,0,0,20).PP.Get(CurrentBar); 

always returns the value 0, whereas

double mainpivot = 0; 
mainpivot = Pivots(PivotRange.Daily,HLCCalculationMode.CalcFromIntradayData,0,0,0,20).PP.Get(CurrentBar); 

works correctly.

Any help would be appreciated, just trying to draw clean rectangles behind price.

Harry, with which data feed are you working? Would it provide native daily bars to calc those pivots in the daily data mode?

[Harry]

I use Kinetick data for EOD and Interactive Brokers for Intraday Data.

I tested this while being not connected -> no access possible,
