highest(10, high()) one bar ago?

[franzmey]

Hi,

how can I manage the problem, that the value for a highest high not include the current bar?

Why not use a for() command to load an array.

If you provide the EFS code, maybe I can help.

[franzmey]

I am new in EFS2 programming, I am a Visual Basic and TradeStation programmer, I dont no how is the syntax for the for()-command.

I have only the documents in the doc-folder to train the EFS2-syntax.

You are right, that I can manage it with the for()-command, maybe you have a small-example to handle the highest-high-problem for one bar ago.

Franz,

EFS and EFS2 is an extension of JavaSript, FWIW, the knowledgebase is under the Support tab, here is a link

Use highest(length,offsetSeries(high(),nn)) where nn is the value by which you want to offset (ie displace). Positive numbers displace forward, negative backwards.
If instead you want to offset the whole plot then use offsetSeries(length,high()),nn)

First of all, get the latest help.chm files here! I'm not sure if this is all that is available, but it's what I have found so far.

http://share.esignal.com/groupcontents.jsp?name=Specialty+Scripts&folder=EFS+Help+File

Put it on your desktop and open it when needed.

Secondly, if you want me to write the script example, I would be more than happy to, but haven't used the "highest" or "hhv" function before and do it manually. Essentially, it is constructed something like what follows:

SPer = 10;
vHigh = getValue("High",0 , -SPer);
HHigh = 0;
LHigh = 0;

for(i = 1; i < SPer; i++) // start with the previous bar
{
LHigh = vHigh[i];
if(LHigh > HHigh) HHigh = LHigh;
}


debugPrintln(HHigh);


The last bar in any series of bars starts with index zero (0) and moves left. We simply skip the last bar by starting with offset 1 instead of zero.

This snipet works in one of my VMA EFS files.

LOL! Alexis always faster than me and a LOT more knowledge about EFS.

LOL!

However, your method isn't so clear in the HELP file, especially for beginners!

******************************************
New in EFS2. This function will return the highest value found in a series within numBars number of bars.

Parameters

numBars
the number of bars back to search

series
the series in which to search for the value



Usage

function main() {
var myVar1;

//find the highest-high over the last 50 bars
myVar1 = highest( 50, high() );

}
*************************

No "OFFSET" shown available in help file as a function of the offsetSeries() variable.

No "OFFSET" shown available in help file.

It is in the Help file under Series Functions. Copy of the help file is also available in the EFS KnowledgeBase under EFS Function Reference and EFS2 Function Reference

True, I didn't express myself properly. To a beginner, embedding functions within variables within another function may be hard to grasp. The other item is that while the one sentence function may work the same as what I did manually, it lacks the "functional flow" to the code for a beginner. One must memorized the whole EFS library in order to know what is available before coding.

OTOH, with simple stuff, the same functionality can be obtained that allows a beginner to get a handle on things with minimum intrinsic knowledge.

Millions of ways to skin a cat, who cares so long as the cat gets skinned?

Just a beginner trying to help other beginners... maybe I should just shut up and leave it up to ya'll!

I understand what you are saying and that is why together with EFS2 eSignal also introduced the Toolbox which helps build all these functions merely through point and click. To access the Toolbox click the f(x) icon in the Formula Editor

Just more excellence from ya'll! I hadn't noticed that since I upgraded.

I'm overloaded with all the help now! Love it! Never the less, my stuff works in its simplistic fashion for now. I hope to ellaborate on a new strategy EFS in progress and the help ya'll have provided saves tons of work!

Thanks again!

[franzmey]

Tex50, thank you for your for()-command-example, works fine!

I though, that its easier with EFS2, for example the following codes (which dont work):

return(highest(10,offsetSeries(high(),-1);

or

HH = highest(10,high());
return(HH(1));

I get no chart with above code.

May be I have to accustom to the way of writing, like high(-1) instead of high(1)...

FYI highest(10,offsetSeries(high(),n)) does work (see this reply earlier in this same thread for the syntax).
Here is a sample script and the result plotted on the chart. In the image the red plot is the one that is offset
Alex

function preMain(){
    setPriceStudy(true);
    setStudyTitle("test");
    setCursorLabelName("no offset",0);
    setCursorLabelName("offset",1);
    setDefaultBarFgColor(Color.blue,0);
    setDefaultBarFgColor(Color.red,1);
}

function main(){

    return new Array (highest(10,high()), highest(10,offsetSeries(high(),1)));
} 

[franzmey]

Alex you are right!


One more question for today:

How can I draw a Session-Break-Line, when I use setDefaultBarBgColor? Its normal, that I cant draw anything, when I use setDefaultBarBgColor?
