total number of bars onrender and period

[frankduc]

Draw.TextFixed(this, "sumvolfibo", sumvolfibo, TextPosition.TopRight);

If i supply ther variable i get 2 error messages:

NinjaScript File Error Code Line Column
SampleDisplayBarsAgo.cs The overloaded method that best matches 'NinjaTrader.NinjaScript.DrawingTools.Draw.TextFix ed (NinjaTrader.NinjaScript.NinjaScriptBase, string, string, NinjaTrader.NinjaScript.DrawingTools.TextPosition) ' has invalid arguments CS1502 769 6

NinjaScript File Error Code Line Column
SampleDisplayBarsAgo.cs Argument 3: Can not convert from 'double' to 'string' CS1503 769 41

You a re talking about 2 different things.
Is it possible on render to get my variable in the chart with

Draw.TextFixed(this, "sumvolfibo", sumvolfibo, TextPosition.TopRight);

What is Text Rendering ? i dont see the difference with Draw.TextFixed(this, "sumvolfibo", sumvolfibo, TextPosition.TopRight); it will produce the same error message.


For the vertical line i came up with this code:

foundIndex = barIndex;
int yByValue = chartScale.GetYByValue(foundIndex);
float chartScaleYValue = chartScale.GetYByValue(yByValue);
float chartScaleXValue = ChartBars.GetBarIdxByX(chartControl, cursorPointX);
SharpDX.Vector2 startPoint = new SharpDX.Vector2(chartScaleXValue);
SharpDX.Vector2 endPoint = new SharpDX.Vector2(chartScaleYValue);


SharpDX.Direct2D1.SolidColorBrush customDXBrush = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, SharpDX.Color.DodgerBlue);


RenderTarget.DrawLine(startPoint, endPoint, customDXBrush, 2);


customDXBrush.Dispose();



It compile and there's in log that message:

2019-07-16 14:20:45	NinjaScript	Multiple Bartypes with the same BarsPeriodType were found. Ignoring NinjaTrader.NinjaScript.BarsTypes.MirrorBarsType

My coordinate are wrong i am all mixt up. Its getting close i get a line just not at the right place.

Hello frankduc,

If you are having trouble writing syntax and are receiving compiler errors, I suggest using the Strategy Builder to generate syntax so you can better learn how to write it. For example, you could use Draw.TextFixed in the Strategy Builder and observe that syntax to see how it should be written. You could also specify a variable with Draw.TextFixed in the Builder and click View Code to specifically see how that code is written. Writing proper syntax will be required when working with unlocked code. I suggest doing this to better learn Drawing Tools so you are not facing the same challenges as with using SharpDX and OnRender which is reserved for advanced programmers.

The compiler error for BarsTypes is mentioning that you have a BarsType on your platform that is using a BarsPeriodType index that is already in use. Please see how the UniRenko BarsType adds a unique index at line 39 and please see the documentation below if you want to fix this BarsType. Otherwise, I suggest right clicking on the BarsType and selecting "Exclude from compilation."

Our recommendation for working with SharpDX rendering would be to create small scripts where you can test working rendering code and you can compare it with any custom implementation you are working on.
