Lowest Low Value

[Behzadgof]

For some reason I get a null for lowestlow value. Can you please tell what I am doing wrong? It was working before! Also is there any thing different between "lowest" and "llv"? I read the documentations however I did not find any difference between the two.




function preMain()
{
setPriceStudy(true);

}


function main()
{


var blnNewBarTrigger = getBarState();
var i=getOldestBarIndex();
i=-i;
var vLowestLow

if ((blnNewBarTrigger == BARSTATE_NEWBAR))
{


debugPrintln("Oldest Bar Index = " + i);


vLowestLow = llv(i, low());


debugPrintln("vLowestLow = " + llv(i, low()));

}


}

Re: Lowest Low Value

As far as I know in order to return a value the lowest() and llv() functions (which are the same btw) require at least a number of bars that is twice that of the length parameter
This is also true of the Donchian Study ie upperDonchian() and lowerDonchian() which are the same as highest(), hhv(), lowest() or llv() but provide some additional features. To verify this load the Donchian Study in Basic Studies and you will see that it will not plot unless the length is half or less than the total number of bars loaded in the chart.

LowestLow

that is true, by reducing the number it will work. But why is that? Is that an esignal limitations? I have been going crazy over this on why my code does not work. If so then I have to write my own function to do that I guess.


Thanks

Re: LowestLow

That is more than likely due to some internal error checking that makes sure that there are enough bars to prime the study and that is simply set to twice the length. I often do the same thing with some of the functions in my libraries.
Anyhow it is very easy to write a function to do what you are trying to accomplish

Lowest low

Thanks; I modified it a little so it is working fine now.
Is there an easy way to find the index of the lowest low?


function preMain()
{
setPriceStudy(true);

}

var blnNewBarTrigger;

var vOldestBarIndex=0;



function main()
{
blnNewBarTrigger = getBarState();

if ((blnNewBarTrigger == BARSTATE_NEWBAR))
{
var vLowestLow=0;

vOldestBarIndex=-getOldestBarIndex();
vOldestBarIndex =vOldestBarIndex/2;

vOldestBarIndex= RoundNumbers(vOldestBarIndex,1);

debugPrintln("Oldest Bar Index = " + vOldestBarIndex);

vLowestLow = llv(vOldestBarIndex, low());

debugPrintln("*************vLowestLow = " + vLowestLow );

}

}

function RoundNumbers(vNum,Percision)
{

var vNumber = vNum;
var vPercision = Percision;
vNumber=Math.round(vNumber*vPercision) /vPercision;
return vNumber;
}

See this post for an example of how you can retrieve the bar index

INdex of the lowest bar

I thought there might be a function tht would return the index.


Thanks for your help

You are most welcome
