Problem solved. You need to create a separate pointer and load it. Problem solved. Below is the code.

const predef = require(‘./tools/predef’);
const meta = require(‘./tools/meta’);
const { du, op } = require(‘./tools/graphics’);

class FastCandles {
map(d) {

const open = d.open();
const high = d.high();
const low = d.low();
const close = d.close();

if (open == null || high == null || low == null || close == null) {
return { graphics: { items: [] } };
}

const isUp = close >= open;
const color = isUp ? this.props.upColor : this.props.downColor;

const top = Math.max(open, close);
const bottom = Math.min(open, close);
let height = Math.abs(close - open);

if (height === 0) height = 0.001;

return {
graphics: {
items: [

// :small_blue_diamond: WICK (1 obiekt)
