Autoscale problem with draw objects

[aslane]

I am having issues with autoscaling not working in the following scenario:

Instrument is set to autoscale = false
Indicator set to autoscale = true
Indicator uses drawing objects only (i.e. DrawDot())

In this case, the scale does not get set at all, the chart data is not displayed, and the scale is left at 0 - .25.

If I then add another indicator that uses a plot (i.e. Bollinger) and set it to autoscale, then the scale is set correctly and the data is displayed as expected.

The problem seems to be that indicator I am trying to use does not use a plot, and is depending on the draw objects to set the scale, but NT does not seem to be handling this case.

Simple test is to just draw a dot on the high and low of each bar.

Update: It also does not work if there is a dummy plot added that is never set.

Thanks Aslane,

You are right in that the scale is dependant on the plot and since the indicator does not use a plot, NT does not roll over to any drawn objects to calcualte the min/max for the scale. Will look into to see what can be done.

Hi Aslane !

This is a bug, though the indicator has no plot, the y range should include the objects drawn from indicator, if the AutoScale property of the objects is set to true.

This bug will be fixed with the next update of NinjaTrader. Thanks for reporting !

Kind regards,

Thanks for looking into!

This appears to be working in B7. Thanks.

While this is generally working in B7, I found on more item not working.

Horizontal lines are not included in the algorithm with other drawing objects. So if DrawHorizontalLine() is called with autoscale=true, that object is not included in the autoscale algorithm.

Same as original issue in that the Instrument has autoscale=false, while the ind creating the horizontal line is set to autoscale=true.
