Hello Pcomm69,

Thanks for your note.

The way to access a plot value from another script is like the following:

if (EssaiIndic().Plot0[0] > Val)
{
// execute code
}

The indicator will be called as a method and will need the parenthesis following the indicator name. If you would like a specific value, such as the last value, you will need to add a bars ago value such as [0]. Without, this will return the entire dataseries (as a dataseries and not a value).

This is assuming there are no properties for this plot (if there are they will need to be added to the call for example EssailIndic(0).Plot0[0]).

Also, as a side note, the indicator wizard will create a public variable for your Plot0. If this has been removed it will need to be re-added. This is in the properties section. Ignore this if you have not manually removed this.

[Browsable(false)]
[XmlIgnore()]
public DataSeries Plot0
{
get { return Values[0]; }
}


Let me know if this does not resolve your inquiry.

Thanks
all is good

I know that,

[Browsable(false)]
[XmlIgnore()]
public DataSeries Plot0
{
get { return Values[0]; }
}
i ll be put it

but wich is the precise difference between
get { return Values[0]; }
and
get { Update(); return Values[0]; }

Hello,

The Update() method refreshes the chart.

I imagine that this would refresh the chart before returning your value.

However, I have never seen this in particular coded this way before.

I recommend you try with and without. My guess is it will be exactly the same.

and just a question i have 3 parameters in EssailIndic ?
does it :
EssailIndic(0,0,0).Plot0[0])
or
EssailIndic(0),(0),(0).Plot0[0]

with3 good declaration like that in Properties
[Gui.Design.DisplayName ("Daily ATR Length")]
[Category("Parameters")]
public int DailyATRLength
{
get { return dailyatrlength;}
set { dailyatrlength = Math.Max(1, value); }
}

Hi Pcomm69,

The proper use for 3 parameters would be:

EssailIndic(0,0,0).Plot0[0]

You should not need to run Update() in the getter of a Plot. It is for ensuring that you get the correct current value for any exposed variable this is not a Plot.

koganam,

Thank you very much for your input here.

I have now learned this as well.
