Autoscaling Indicators

[ECI-Ed]

I don't understand why I can't get the chart to autoscale to the bar range and ignore the indicator lines I'm drawing. There should be at least some way to set this in the indicator code if not in the settings. Shouldn't there? I attached a chart to illustrate what I'm referring to. As you can see in the chart all the price bars are in the upper half of the screen and its apparently scaling on the PrevHigh on the top and the ONLow on the bottom. Any idea if there is a way to fix this?

Ed, in the Visual settings for the indicator there's an AutoScale property, if you set this to false - would you still see an issue?

[ECI-Ed]

Yes, the AutoScale property is set to false on both these indicators both in the indicator settings and AutoScale = false has been added to both indicators Initialize section.

Ok, would make sense if those lines are not created via plots - then the drawing overloads would have a separate autoScale parameter you would set from the code directly.

Autoscaling Indicators

Bertrand,

Thanks for your expeditious response. So I tried converting these lines from a plot to a DrawLine, and apparently I don't have a clue how to do this. Though the indicator compiled without errors, the lines disappeared from the chart. I've attached the Previous Day High and Low indicator. Could you please take a look and see what I'm doing wrong.

Thanks in advance.

Any error in your Control Center log tab? Looks like you miss a CurrentBars check to prevent accessing unavailable bars at the chart series start.

You also use just one tag id for the drawing object, thus updating only one object - meaning you do not keep the history of objects, as just the current one is continuously modified.

Autoscale Indicators

OK, so I implemented the changes you specified in your response to my post and the Previous day High and Low are showing up again on my charts however the chart is still not autoscaling to the pricebars only. It is still autoscaling to the Previous Day high and low just like it was doing when I was plotting the lines. I have attached my new code. Please HELP!!

You still have the DrawText set to autoscale for the PrevHigh. Can you try setting these to false and see if it is still autoscaling?

DrawText("PivotTag1",false,"PrevHigh",-1,prevHigh,0,Color.Red,textFont,StringAlignment.Ne ar, Color.Transparent, Color.Transparent, 0);

DrawText("PivotTag2",false,"PrevLow ",-1,prevLow ,0,Color.Lime,textFont,StringAlignment.Near, Color.Transparent, Color.Transparent, 0);

That did it. I thought that property had a different meaning in DrawText. Silly me.
Thanks a lot.
