Atr

[Bügeleisen]

Hi, i want to calculate a study, based on the ATR. Think, it`s a simple question(for you, not for me):

I don`t want to plot the ATR, but the result of

ATR(10)*Close()*200


How to change the Indikator formular?

function main() {

return atr(14);
}

Hello Bügeleisen,

You're closer than you might think. Try changing the return statement to the following.

function main() {

    return atr(10)*close(0)*200;
}

Thank you!! Quick answer!

Is it possible to show the last result of the indikator, instead of plotting the line, to plot the number above the last quote on the right side? Into the quote chart?
Regards

Hello Bügeleisen,

You're most welcome.

EFS does not currently interact with the quote window. However, you can display a text label on the chart to the right of the price bars using the drawTextRelative() function. Set your study to a price study with setPriceStudy(true) in preMain. Then for the drawText function, use 1 or 2 for the bar index parameter, which will draw the text to the right of the price bars. You could use close(0) for the yValue parameter. Pass your custom atr calculation to the text parameter. Lastly, specify a fixed string for the tagID parameter so that only one label will be drawn. You will do this before the return statement in main() and you will also need to remove your atr calc from the return statement so that it does not plot the line. Give it a try and if you have any trouble, post your code.

Hi,
i have tried it:
Now the code draws "ATR(10)*200 , not the result of the "ATR(10)*200.
Above the bar, ok, but: Every bar, not only the last bar
What`s wrong?
Thanks

function preMain() {

setPriceStudy(true);
setStudyTitle("ATR");


}

function main() {

drawTextRelative( 0, AboveBar1, "ATR(10)*200", Color.red, null, Text.PRESET | Text.BOLD, null, 12 );
return;
}

Now the code draws "ATR(10)*200 , not the result of the "ATR(10)*200

That is happening because you enclosed the equation in quotes which makes it a text string. Remove the quotes and you will get the result of the equation written on the chart. Note that the equation should be atr(10)*200 and not ATR(10)*200

Every bar, not only the last bar

As Jason suggested you need to also specify a fixed string as the TagID parameter so that only one instance of the text will be written (ie the last one). Replace the command line with the one enclosed below
Alex

drawTextRelative( 0, AboveBar1, atr(10)*200, Color.red, null, Text.PRESET | Text.BOLD, null, 12, "text" ); 

[Bügeleisen]

Thanks.
A new problem: If the result is e.g. "245", there`s only the first "2" drawn on the right side obove the bar. What`s happens there?

Please post the code you are using and also provide details about the symbol and interval on which you are running the script.

Hi, after restart it was ok. Thank you.
Another question: How to round up the result to a whole decimal place?
thanks

[ACM]

Bugeleisen
To do that you would use the .toFixed(nn) method where nn is the number of decimals you want to display
For example (atr(10)*200).toFixed(2) will return 2 decimals

[Bügeleisen]

Thanks a lot.
Is it possible to change the color of the result number or the backround of the number?
eg.
if (atr(10)*200).toFixed(2)<=5 draw blue
if (atr(10)*200).toFixed(2)>5 and <= 10 draw yellow
if (atr(10)*200).toFixed(2)> 10 draw green

?

Bügeleisen
To do what you want you need to first create two local variables (ie inside main) called for example myValue and myColor to which you assign the value of your equation and a default color

var myValue = (atr(10)*200).toFixed(2);
var myColor = Color.black; 

Once you have done that you can write your conditions using the variable myValue. For each condition you then assign the appropriate color to the variable myColor (see the example below). For a list of colors see this article in the EFS KnowledgeBase.

if (myValue<=5) myColor = Color.blue;
if (myValue>5 && myValue <= 10)  myColor = Color.yellow;
if (myValue> ....) myColor = ....;
//etc 

Then inside the drawTextRelative() command replace the equation and the color with myValue and myColor.
As you seem to have been using eSignal for a while you may find it to your benefit to learn how to program in efs as that will considerably increase your ability to make full use of the program. If you are interested then you may want to start by reviewing the JavaScript for EFS video series. That will provide you with a thorough introduction to programming in JavaScript which is at the foundation of EFS. Then go through the EFS KnowledgeBase and study the Help Guides and Tutorials which will provide you with the specifics of EFS.

Hi, i have added a bgcolor in the code. Now i get the message:
Line 28 Parameter number 10 of funktion drawTextRelative is invalid.
Do you know, what`s wrong?



function preMain() {

setPriceStudy(true);
setStudyTitle("ATR");



}

function main() {
var myValue = ((1/atr(10)).toFixed(2))*100;
var myColor = Color.black;
var mybgColor = Color.black;
if (myValue<=7) myColor = Color.aqua;
if (myValue<=7) mybgColor = bgColor.teal;
if (myValue>7 && myValue <= 18) myColor = Color.olive;
if (myValue>7 && myValue <= 18) mybgColor = bgColor.green;
if (myValue>18) myColor = myColor = Color.navy;
if (myValue>18) myColor = mybgColor = bgColor.blue;

( Line 28) drawTextRelative( 0, AboveBar1, myValue , mybgColor, myColor, null, Text.PRESET | Text.BOLD, null, 14, "text" );
return;
}

[buhrmaster]

Does drawTextRelative have 10 parameters? I think it may have only nine. You may have an extra Null in there.

[Bügeleisen]

0?

I have only added

"mybgColor," in the line.
