Draw Text: Fixed x position based on chart margin

[Unsuitable]

Hi, in NT7 I used graphics.DrawString() to draw a string at a specific location. The indicator would display the amount of contracts that was left in a tick. It would also follow price in the Y but had a fixed X position based on the chart property's margin.

So far I have the NT8 indicator following price in the Y axis using Draw.Text() and Close[0]. However, the only two x positions I can choose is based on time or on the bars. Is there anyway to set it based on the the margin?

Thank you

Welcome to the forums Unsuitable!

NinjaTrader 8 uses SharpDX for custom rendering and uses the OnRender() method for these purposes when NinjaTrader 7 uses GDI+ graphics and the Plot() method. You could use SharpDX to draw text at some defined coordinates on the chart, or you could consider using Draw.TextFixed. We include a SampleCustomRender example indicator with NinjaTrader 8 which describes how custom rendering can be done.

Resource management is important to consider with SharpDX rendering as undisposed brushes and devise dependent SharpDX resources can cause memory leaks and rendering errors if not managed correctly. Please also see the ChartBars, ChartControl and ChartScale documentation for helper methods to convert data points and bar indexes to chart coordinates.

Well I got to the point where I have a SharpDX vector that uses price and chartControl margin. How do I draw text that is fixed to that vector?

Hello Unsuitable,

I have attached a conversion of a NinjaTrader 7 script that uses DrawString which may offer additional direction.

Please let me know if I can be of further assistance.
