Display a Moving Average Value

[pjkowalski]

I would like to simply display the value of a moving average from the current candle. Here is my code:

xSMA200 = sma(200);
var nSMA200 = (xSMA200.getValue(0));

drawTextRelative(-15, BottomRow2, nSMA200, Color.black, null, Text.PRESET | Text.BOLD | Text.ONTOP, "Arial", 10, 200);

This results in "Parameter Number 3 is invalid".
I get the same error if I use: xSMA200.getValue(0) as the third parameter.

If I try: xSMA200.getValue() then [object Series] is displayed on the chart.

It has to be simple solution, but I can not figure it out.
Thanks for your assistance.

Run a null check on the variable to which you assigned the value of the average prior to using it in the drawTextRelative() command eg

xSMA200 = sma(200);
var nSMA200 = (xSMA200.getValue(0));

if(nSMA200 ==null) return;//null check

drawTextRelative(-15, BottomRow2, nSMA200, Color.black, null, Text.PRESET | Text.BOLD | Text.ONTOP, "Arial", 10, 200); 

Once you do this you should no longer get the error message
The error message is due to the fact that while the average is priming it will return null which is not a valid parameter for the drawTextRelative() function

Thank you Alex. That did it.

I have a similar issue... the following code works only when the chart is on a 5 min interval. I want this to populate on any time-frame by picking up the interval using "getInterval()". I keep getting an error mssg "Trin has no properties". What am I missing here? Any help would be greatly appreciated. Thank-you.

If it is better to use "getSeries" then cool, just don't know how to do it...

var vTrinSMA = sma(1, sym("$trin,5"));
var vAddSMA = sma(1, sym("$Add,5"));

var gInt = null;
var bInt = false;

var fpArray = new Array();

function preMain() {

debugClear();

setComputeOnClose(true)

setCursorLabelName("trin", 0);
setDefaultBarStyle(PS_SOLID, 0);
setDefaultBarFgColor(Color.red, 0);
setDefaultBarThickness(3, 0);
setPlotType(PLOTTYPE_LINE, 0);

setCursorLabelName("add", 1);
setDefaultBarStyle(PS_SOLID, 1);
setDefaultBarFgColor(Color.green, 1);
setDefaultBarThickness(3, 1);
setPlotType(PLOTTYPE_LINE, 1);

gInt = getInterval();

function main() {

if(!bInt) {

/* ** Tried this here but didn’t work… only accepts static
interval as defined up top**

var vTrinSMA = sma(1, sym("$trin,gInt"));
var vAddSMA = sma(1, sym("$Add,gInt"));

*/

bInt = true;
}

var Trin = vTrinSMA.getValue(MAStudy.MA);
var Add = vAddSMA.getValue(MAStudy.MA);

debugPrintln(

"Trin:" + Trin.toFixed(2) + " (" + gnTrinVal + ") " +
"Tick:" + Tick.toFixed(2) + " (" + gnTickVal + ")"

);

return new Array (Trin , Tick);

Run a null check on the variable Trin prior to changing its properties through the .toFixed() method
Also replace MAStudy.MA with 0 (or with the appropriate bar index) where you retrieve the values of the vTrinSMA and vAddSMA series using the getValue() method.
