Checking for Fixed Chart Scale Range in OnCalculateMinMax

[TheTradingMantis]

I am using OnCaclulateMinMax to set the chart scale for an indicator that uses OnRender.

When I manually set the chart scale, either by click/dragging the scale or setting the scale in chart scale Properties, the little "F" icon appears but the panel continues to auto scale.

Is there a way I can tell if the chart scale is set to Fixed so I can call base.OnCalulateMinMax instead of my custom scaling code? Or is there another way to resolve this issue?

Thanks,
Greg

Hello Greg,

Thanks for your post.

ChartPanel.Scales[ScaleJustification].Properties.YAxisRangeType would tell you if the indicator's panel is in Fixed or Automatic, but I'm not sure why you would need this in OnCalculateMinMax.

OnCalculateMinMax would be used if we want to override the auto scaling feature of the script. It won't be called when we are in Fixed scaling mode.

I have attached an example that adds a print in OnCalculateMinMax. We can see the print is not seen when the panel is set to Fixed scaling.

I'm also attaching the script so if you would like to further describe the issue you are experiencing, you could modify it to demonstrate what you are trying to do.

We look forward to assisting.

Thanks for the quick response Jim! NinjaTrader support is the best!

I figured out my problem. In OnRender, I was setting chartScale.Properties.YAxisRangeType to "Fixed" for one style of rendering and setting to "Automatic" for all other styles using an else statement. I removed the else statement and everything works as I would expect now.

Thanks,
Greg
