autoscale

[lucyjoy]

Hi

How do i turn autoscale off in an indicator?

Its greyed out and the indicator is printing strange!

Regards

[lucyjoy]

The problem is the scale starts too low at 0 which makes the indicator look weird

Hello lucyjoy,

Thank you for your post.

Please attach a screenshot of your chart to your response so I may investigate this matter further.

Hi thanks

On the right you see tradestation, on the left ninjatrader, i dont understand how tradestation decides the scale but it looks messed up in ninja.

I can manually change the scale which fixes it but how do i get it to plot correct as standard?

Hello lucyjoy,

Thank you for your response.

Is this a custom indicator you have developed? If so, may I test the indicator on my end?

I look forward to your response.

Hello lucyjoy,

Thank you for that file.

You will need to set the AutoScale in the Initialize() method:

        protected override void Initialize()
        {
	 AutoScale = false;

For information on AutoScale please visit the following link: http://www.ninjatrader.com/support/h.../autoscale.htm

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

Hi

I want the scale on the emahisto indicator to match the scale on the main chart because it does not look right at moe



the top number is ok but the bottom should be more like 14800 instead of 0

Hello Lucy,

Thank you for your response.

With the Bar Plot Style you will see the scaling from 0 to the value of the indicator. This can show large Bars with a moving average as the value of the moving average is likely extremely higher than the 0 line.

There is no method to use the current scaling of one panel for another panels scaling. You will need to either develop a custom plot for this indicator or use another Plot Style.

You can view a sample of custom plotting by going to the NinjaTrader Control Center > Tools > Edit NinjaScript > Indicator > CustomPlotSample.

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

I was hoping you could help me code something please.

could i not make another indicator with

AutoScale = true;

MAX(EMAHISTO(CurrentBar - ChartControl.FirstBarsPainted))[0];
MIN(EMAHISTO(CurrentBar - ChartControl.FirstBarsPainted))[0];

im just not sure how to make this indicator please help.

Hello Lucy,

Thank you for your response.

You will need to include the Period for the MAX and MIN:

MAX(EMAHISTO(CurrentBar - ChartControl.FirstBarsPainted), [B]maxPeriod[/B])[0];
MIN(EMAHISTO(CurrentBar - ChartControl.FirstBarsPainted), [B]minPeriod[/B])[0];

For information on MAX and MIN please visit the following links:

• MAX: http://www.ninjatrader.com/support/h...aximum_max.htm
• MIN: http://www.ninjatrader.com/support/h...inimum_min.htm

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

            private int myInput0 = 1; // Default setting for MyInput0
        // User defined variables (add any user defined variables below)
        #endregion

        /// <summary>

        protected override void Initialize()
        {
            Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
            Overlay				= false;
			AutoScale = true;
        }

        /// <summary>

        protected override void OnBarUpdate()
        {
            // Use this method for calculating your indicator values. Assign a value to each
            // plot below by replacing 'Close[0]' with your own formula.
            MAX(EMAHISTO(CurrentBar - ChartControl.FirstBarsPainted), 10)[0];
        }

Here is my indicator

Hello Lucy,

Thank you for your response.

What are you trying to achieve with MAX, MIN and the use of the ChartControl.FirstBarsPainted?

I look forward to your response.
