How can I get access from strategy to plot data in my indicator?

[handlar]

There is a simple Indicator, It simple connect highs and lows of bars. http://prntscr.com/f99j3h

There are two plots in Indicator, which added using AddPlot() http://prntscr.com/f99kgj

DataBox show correctly both plots http://prntscr.com/f99kpb BUT when I try to get the value of second Plot, I can not do this.

When I call Indicator from Strategy like this: http://prntscr.com/f99of8 everything works fine, but I get only the first Plot ("testH"). Look at this http://prntscr.com/f99oq1 each plot is equals to Hight.

The question: how can I get an access to second Indicator's plot (I mean "testL")?

Indicator: testLowsAndHighs.cs
Strategy: simpleHL.cs

Hello,

Thank you for posting.

In this case, you just need to add some public Properties so you can differentiate the plots when calling the indicator from other scripts. The Indicators [0] value would relate to the first added plot only:

myIndicator[B][0][/B]

I usually recommend reviewing the Bollinger indicator as it shows the syntax to create 3 plots and also be able to call them from another script.

The specific syntax you would need is the following:

[Browsable(false)]
[XmlIgnore()]
public Series<double> TestH
{
	get { return Values[0]; }
}

[Browsable(false)]
[XmlIgnore()]
public Series<double> TestL
{
	get { return Values[1]; }
}

The property returns the Values[PlotIndex] for the plot it should be associated with, then from another script you can access the values like the following:

double h = myIndicator().TestH[0];
double h = myIndicator().TestL[0];

I look forward to being of further assistance.

One more question. Can I get a color of the Plot in any way? For example: I have one plot and I change the color depends of price (from green to red and again). How can I check is the color red or green on current bar?

Hello,

Thank you for the reply.

Checking the Color of a plot specifically would not be a good way to try and get signals, instead, I would suggest either to use the same logic that colors the plot to start with for the other action. Alternatively, you could make a plot and set specific values as signals.

One example would be if the indicator would be called on by another script, in that case, you would need to make a plot and then make signal values based on when the color changes in the logic.

You could use specific values like 1,0,-1 for triggers, for example, 1 could mean green, 0 no signal and -1 red.

The indicator in which colors the plot would add the extra plot used for signals and also would set the values, then in any other indicator you could call on it like shown in the previous post.

[Browsable(false)]
[XmlIgnore()]
public Series<double> SignalPlot
{
	get { return Values[2]; }
}

From another indicator:

if(myIndicator().SignalPlot[0] > 0)
{
}

I look forward to being of further assistance.
