I don't completely understand what you are trying to do, but the first value of a bar is the open.

So if you have defined the variable "startvalue1" then

Code: Select all

startValue1 = Open;

should give you the first value of every bar.

Use

Code: Select all

 Plot1(startValue1);
to verify that visualy on a chart.

Thanks for the reply, sorry for my bad explanation!

I need the absolute first bar of a dataseries.
With my example I get the closes of two symbols (every close of each BAR)

Code: Select all

inputs: DataSeries1( Close of data1 ), DataSeries2( Close of data2 ) ;


But I need now to know how can I grab the values of the first bar.
Can you help, would be very nice!

In easyLanguage-refguide I found only this:
For example, the following expression is referencing the closing price from 2 bars ago:

Code: Select all

Close[2]
But how to grab the first bar and not only a few bars ago?

This should help:

Code: Select all


Variables:
              FirstBarOpen (0),
              FirstBarHigh  (0),
              FirstBarLow    (0),
              FirstBarClose (0);


If CurrentBar = 1 then begin

FirstBarOpen = Open;
FirstBarHigh = High;
FirstBarLow = Low;
FirstBarClose = Close;

end;



This will store the Open, High, Low and Close of the very first bar on your chart in the four variables.
