TypeError: variable has no properties

[Guest]

Hi,

The following is a snippet of my code, I'm getting error: "TypeError: LMA0 has no properties".

Please help. Thank you.

var xSMA = efsExternal("MA.efs", "close", fastMAlength);
    var xLMA = efsExternal("MA.efs", "close", slowMAlength);
    
    SMA0 = xSMA.getValue(0);
    SMA1 = xSMA.getValue(-1);
    SMA2 = xSMA.getValue(-2);
    LMA0 = xLMA.getValue(0);
    LMA1 = xLMA.getValue(-1);
    LMA2 = xLMA.getValue(-2);

debugPrintln(LMA0);

Correction.

var xSMA = efsExternal("MA.efs", "close", fastMAlength);

    var xLMA = efsExternal("MA.efs", "close", slowMAlength);

    SMA0 = xSMA.getValue(0);
    SMA1 = xSMA.getValue(-1);
    SMA2 = xSMA.getValue(-2);
    LMA0 = xLMA.getValue(0);
    LMA1 = xLMA.getValue(-1);
    LMA2 = xLMA.getValue(-2);

debugPrintln(LMA0.toFixed(2));

You need to perform a null check on the variable being used prior to applying the .toFixed() method eg
if(LMA0 == null) return;

This will happen at the very start of calculating your moving average study. The study will return null until it has enough samples to compute the first moving average. So you are assigning null to LMA0 and then trying to print it, which efs doesn't like.

A simple fix would be
if(xLMA.getValue(-2) != null)
assign values and print inside if statement
