Horizontal line on a graph

Custom Indicators
1

Hello

Can someone give me the code to draw a line on tradovate graph please?

I tried this code but does not work.

const predef = require(“./tools/predef”);
const meta = require(“./tools/meta”);

class SLINE {
init() {
}

map(d) {
    const positionY = 16430;


    const draw = this.context.drawingContext;

    const chartWidth = this.context.chartWidth;

    const line = draw.line(0, positionY, chartWidth, positionY);
    line.stroke({ width: 1, color: 'white' });

    return line;
}

}

module.exports = {
name: “SLINE”,
description: /i18n/ “SLINE”,
calculator: SLINE,
params: {

},
tags: [predef.tags.MovingAverage],
schemeStyles: predef.styles.solidLine("#8cecff")

};

thank you
