referencing a symbol within an EFS formula

[uhehs]

I'm trying to add $TRIN in a formula, but am getting a Reference Error.

Example: ($TRIN/2)

Is this the correct way to reference the value for $TRIN?
I tried quotes, etc, etc.

Thank you in advance for any help.

var trin;
...
trin = close(0, sym("$TRIN"));

Thanks. BUT, where do I place the specific code? I attached what I have now BUT I am getting "ReferenceError: $TRIN is not defined"

//{{EFSWizard_Declarations
var vLastAlert = -1;
var TRIN;
var TRINQ;
var ADV;
var ADVQ;
var DECL;
var DECLQ;

//}}EFSWizard_Declarations


function preMain() {
/**
* This function is called only once, before any of the bars are loaded.
* Place any study or EFS configuration commands here.
*/
//{{EFSWizard_PreMain
setPriceStudy(true);
setStudyTitle("SHEHU LONG");

//}}EFSWizard_PreMain

}

function main() {
/**
* The main() function is called once per bar on all previous bars, once per
* each incoming completed bar, and if you don't have 'setComputeOnClose(true)'
* in your preMain(), it is also called on every tick.
*/




//{{EFSWizard_Expressions

TRIN=close(0,sym("$TRIN"));
TRINQ=close(0,sym("$TRINQ"));
ADV=close(0,sym("$ADV"));
ADVQ=close(0,sym("$ADVQ"));
DECL=close(0,sym("$DECL"));
DECLQ=close(0,sym("$DECLQ"));

//{{EFSWizard_Expression_1
if (
($TRIN+$TRINQ)/2 < 1 &&
((($ADV+$ADVQ)/2)-(($DECL+$DECLQ)/2)) > 0
) onAction1();
//}}EFSWizard_Expression_1

//}}EFSWizard_Expressions


//{{EFSWizard_Return
return null;

You define the variables:
"TRIN" for the close of $TRIN,
"TRINQ" for the close of $TRINQ, etc.

Yet you use "$TRIN + $TRINQ" etc. in your calculations instead of the variables you created.

Just remove the "$" from your conditional statement as I did below.

(TRIN+TRINQ)/2 < 1 &&
(((ADV+ADVQ)/2)-((DECL+DECLQ)/2)) > 0
) 

You can't use the symbol because it just identifies the instrument. The values used in calculations are the open, high, low, close, etc, or calculations based on values derived from the symbol's price action.

Thank - I'm there!

For education pruposes, this type of thing cannot be done using the Formula Wizard - correct? (I do not see a way to declare the variables using the Wizard.)

One more thing: the signal only shows on the current bar, but I want it to stick to preceeding bars where the condition was met.

(Using the wizard) This is what I have noted as my visual display:

//{{EFSWizard_Actions
//{{EFSWizard_Action_1
function onAction1() {
drawShapeRelative(0, high(), Shape.UPARROW, "", Color.RGB(0,0,255), Shape.TOP, "long");
vLastAlert = 1;
}
//}}EFSWizard_Action_1

//}}EFSWizard_Actions

by coding outside the Wizard, my code does not open in the Wizard.

So I am at the mercy of coding! What I posted was generated by the Wizard when I started my EFS in there.

Like I wrote, the signal only appears on the current bar - and not on any preceeding bars. (Where I know the condition to have been true).

It must be something simple, hopefully someone else will step in to help. Here is what I have:


//{{EFSWizard_Declarations
var vLastAlert = -1;
var TRIN;
var TRINQ;
var ADV;
var ADVQ;
var DECL;
var DECLQ;

//}}EFSWizard_Declarations


function preMain() {
/**
* This function is called only once, before any of the bars are loaded.
* Place any study or EFS configuration commands here.
*/
//{{EFSWizard_PreMain
setPriceStudy(true);
setStudyTitle("SHEHU LONG");

//}}EFSWizard_PreMain

}

function main() {
/**
* The main() function is called once per bar on all previous bars, once per
* each incoming completed bar, and if you don't have 'setComputeOnClose(true)'
* in your preMain(), it is also called on every tick.
*/

TRIN=close(0,sym("$TRIN"));
TRINQ=close(0,sym("$TRINQ"));
ADV=close(0,sym("$ADV"));
ADVQ=close(0,sym("$ADVQ"));
DECL=close(0,sym("$DECL"));
DECLQ=close(0,sym("$DECLQ"));


//{{EFSWizard_Expressions



//{{EFSWizard_Expression_1
if (
(TRIN+TRINQ)/2 < 1 &&
(((ADV+ADVQ)/2)-((DECL+DECLQ)/2)) > 0
) onAction1();
//}}EFSWizard_Expression_1

//}}EFSWizard_Expressions


//{{EFSWizard_Return
return null;
//}}EFSWizard_Return

}

function postMain() {
/**
* The postMain() function is called only once, when the EFS is no longer used for
* the current symbol (ie, symbol change, chart closing, or application shutdown).
*/
}

//{{EFSWizard_Actions
//{{EFSWizard_Action_1
function onAction1() {
drawShapeRelative(0, high(), Shape.UPARROW, "", Color.RGB(0,0,255), Shape.TOP, "long");
vLastAlert = 1;

See this or this post for an explanation of why this is happening and a way to resolve it

DONE - thank you.
