Problem calling efs

[ndeacon]

I am calling a file (attached below) and attempting to pass the contents of the array to another EFS.

I have amended Jurik's JMADWMAMACD file to get the MACD for the previous two bars as you will see in the attached file.

I am calling the values as follows:

if (getBarState() == BARSTATE_NEWBAR) {

var myMACD = call("CalledCleanMACD.efs");
vMACD = myMACD[3];
vMACDminus = myMACD[4];
vMACDminustwo = myMACD[5];
}

In the calling EFS I am getting an error when I try to load it which is saying "TypeError: myMACD has no properties".

Anyone got any idea where I am going wrong?

Thanks.

Elements in the array are numbered starting from [0] so you need to change the variables to myMACD[2], [3] and [4]. Then run a null check on each of those variables.
For some examples see this thread

Hi Alex,

I have amended the called formula and attached it below. I have also done as you suggest by amending the bracketed figures and running a null check in the calling formula, but I still get the same error, i.e. "TypeError: myMACD has no properties". My calling formula now looks like this:

if (getBarState() == BARSTATE_NEWBAR) {

var myMACD = Call("LastCalledJMADWMAMACD.efs");
vMACD = myMACD[0];
vMACDminus = myMACD[1];
vMACDminustwo = myMACD[2];

if (vMACD == null || vMACDminus == null || vMACDminustwo == null) return;
}

The error is occuring on the line

vMACD = myMACD[0];

I cannot see why this is not working. Am I missing something very obvious? Many thanks Alex for your help.

I can load the called formula (attached) and it is giving me exactly the output I want, but I cannot call that output from the calling formula.

BTW in the calling formula, I have set the above three variables as global variables (before PreMain) and made them equal to null, as below.

var myMACD = null;
var vMACD = null;
var vMACDminus = null;
var vMACDminustwo = null;

Any help greatly appreciated.

Deax.

Folks,

I have solved the problem.
