Vertical Line Turned On and Off with Symbol change

[ketoma21]

What's wrong with this code?

I have a switch if turn on it will draw a vertical line and if the Symbol is changed the switch is turn Off and the line is deleted.

Thank you very much

var vMA1 = null;
var sSymbol1 = null;
var sSymbol2 = null;

function preMain() {

setPriceStudy(true);
setStudyTitle("10MA");
setCursorLabelName("10MA", 0);
setDefaultBarStyle(PS_SOLID, 0);
setDefaultBarThickness(2, 0);
setPlotType(PLOTTYPE_LINE, 0);

var fp1 = new FunctionParameter("MA1Length", FunctionParameter.NUMBER);
fp1.setLowerLimit(1);
fp1.setDefault(10); //Edit this value to set a new default

var fp2 = new FunctionParameter("MA1Offset", FunctionParameter.NUMBER);
fp2.setDefault(0); //Edit this value to set a new default

var fp3 = new FunctionParameter("MA1Source", FunctionParameter.STRING);
fp3.setName("MA1Source");
fp3.addOption("Close");
fp3.addOption("High");
fp3.addOption("Low");
fp3.addOption("Open");
fp3.addOption("HL/2");
fp3.addOption("HLC/3");
fp3.addOption("OHLC/4");

var fp5 = new FunctionParameter("Vert", FunctionParameter.NUMBER);
fp5.setDefault(0); //Edit this value to set a new default
}

function main(MA1Length,MA1Offset,MA1Source,MA1Type,Vert) {


if (vMA1 == null) vMA1 = new MAStudy(MA1Length, MA1Offset, MA1Source, eval(MA1Type));

if (Vert == 1) {
if (sSymbol2 == null){
sSymbol2 = getSymbol();
}
sSymbol1 = getSymbol();
if (sSymbol1 == sSymbol2) {
drawLineRelative(-1, -100, -1, 100, PS_SOLID, 2, Color.grey, 0 );
} else {
Vert = 0;
removeLine( 0 );
}
}

return (vMA1.getValue(MAStudy.MA));

When I change symbols the line does not get deleted
What exactly are you trying to accomplish?

Thank you very much Alexis for the quick respond.

I'm trying to turn OFF the switch when I change Symbol

to erase the line when I change Symbol

For Vert to go back to 0 until I switch it ON again

Here is one solution to what you are trying to accomplish.
You set the line by clicking the yellow button in the bottom left corner of the chart. Any time you change symbol, interval or reload the efs the line is cancelled
Hope this helps
