parameter passing to main()

[philtong]

I can pass a parameter to a function within an efs fine.
However, I'm having a problem with the parameter to main().
I followed some examples but I guess I'm missing something.
I loaded the efs below and did "edit studies" on it but the parameter caclType doesn't show up in the parameter list.
Do I need something else?
Thank you in advance.


function main(calcType) {

var nState = getBarState();
var indcurr = getCurrentBarIndex();
f((nState == BARSTATE_NEWBAR) ||
(calcType = "now" && indcurr == 0))
{ ... }
}

Hi,

Your main statement looks fine.

>function main(calcType) {

I would set a default for calcType:

If (calcType == null)
calcType = "now";

I also think you have a problem here:


>var nState = getBarState();
>var indcurr = getCurrentBarIndex();
>if((nState == BARSTATE_NEWBAR) ||
>(calcType = "now" && indcurr == 0))

In that I suspect you want to say "calcType ==" rather than just "calcType =".




}

oops. you're right about ==.
however, problem remains where calcType doesn't appear in the formula parameters section of "edit studies".

i added
var calcType = "";
function main(calcType) {
debugPrintln("ct="+calcType)

the display shows "undefined".

Could you post your entire code?

It would make debug easier.

Philtong:

1. You need to unload and then re-load scripts when you add/remove main parameters for them to show up in Edit Studies

2. You should not declare these parameters outside of main(). In your second message you showed:

var calcType = "";
function main(calcType) {
debugPrintln("ct="+calcType)
}

Get rid of the first line (e.g., var calcType="") and it should work fine.

Thank you.

Removing and Reloading did it.
(also removed the var declaration.
