Custom Indicator to read MACD parameters and values

[nothingbutprofits]

Hi,

As I'm working on the custom indicator that will read MACD settings and the macd/avg/hist values (using plots Values[x]) without loading the MACD indicator inside the indicator.

Note: Both custom indicator and MACD indicator are already on the same chart.

I looked at MACD indicator code (at bottom of MACD.cs):

namespace NinjaTrader.NinjaScript.Indicators
{
public partial class Indicator : NinjaTrader.Gui.NinjaScript.IndicatorRenderBase
{
private MACD[] cacheMACD;
public MACD MACD(int fast, int slow, int smooth)
{
return MACD(Input, fast, slow, smooth);
}

public MACD MACD(ISeries<double> input, int fast, int slow, int smooth)
{
if (cacheMACD != null)
for (int idx = 0; idx < cacheMACD.Length; idx++)
if (cacheMACD[idx] != null && cacheMACD[idx].Fast == fast && cacheMACD[idx].Slow == slow && cacheMACD[idx].Smooth == smooth && cacheMACD[idx].EqualsInput(input))
return cacheMACD[idx];
return CacheIndicator<MACD>(new MACD(){ Fast = fast, Slow = slow, Smooth = smooth }, input, ref cacheMACD);
}
}
}

I understand that MACD indicator is public accessible for other indicator.

is it possible for you to provide us the basic sample indicator that will allow for accessing to MACD settings and read the values directly without using AddChartIndicator inside the custom indicator?

It will be a big help for us.

Thanks.

Hello nothingbutprofits,

Thanks for your post.

You could access values from the MACD indicator without using AddChartIndicator() by assigning a value of the MACD indicator to a double variable.

An example would look something like this.

// Prints the current MACD value
double value = MACD(12, 26, 9)[0];
Print("The current MACD value is " + value.ToString());

Note that AddChartIndicator() adds an indicator to a strategy only for the purpose of displaying it on a chart.

If you would like to plot the MACD values in a custom indicator, you could assign the value of the MACD indicator to a plot created using AddPlot().

See this help guide page for more information and examples of accessing MACD indicator values: https://ninjatrader.com/support/help...gence_macd.htm

Also, see this help guide for more information about AddPlot(): https://ninjatrader.com/support/help...t8/addplot.htm

And, see the attached example script which demonstrates assigning the MACD value to a double variable and assigning that double variable to a plot.

Let us know if we may assist further.

Thanks for your response.

I tried your MACDCustomIndicator ..and realized that I may need to explain more in details. (my apologies)

1) The indicator will be used as a "tool" to read MACD parameters and values, not to display the indicator on chart. It will be used for linking to "button" to display the MACD parameters/last values (macd, avg, diff)

I see the MACD (12,26,9)[0] settings there.

Is it possible for the custom indicator to read the actual MACD settings (fast, slow, smooth) from the existing MACD indicator on the chart, instead of dummy values (12,26,9) and display it in draw.text on PricePanel chart?

Hello nothingbutprofits,

Thanks for your note.

You would not be able to read the Fast, Slow, and Smooth indicator properties being used by an existing MACD indicator that is on the chart. You would only be able to access the MACD plots that are listed in the MACD help guide page below (MACD, Avg, Diff).

To get the values of indicators existing on a chart, see post #6 of this forum thread: https://ninjatrader.com/support/foru...ors-in-a-chart

Understood. I'm just asking.

To get the values of indicators existing on a chart, see post #6 of this forum thread:

This idea will work...as the best workaround.

You're awesome..many thanks!
