By chart patterns I mean this ones:
Restriction:
- they are available only for paid plans
TradingView.searchIndicatorsomehow does not find them- from ws messages on trading view it seems that identifiers are something like
BearishFlagCP@tv-chart_patterns-26but attempt to retrieve it fails with error that indicator is undefined - also from indicator search in inspector I see that its data id attribute is
BearishFlagCP@tv-chart_patterns
How I tried to retrieve it:
import TradingView from '@mathieuc/tradingview';
var username = 'hello'
var password = 'world'
var user = await TradingView.loginUser(username, password, false)
var client = new TradingView.Client({
signature: user.signature,
token: user.token,
});
var chart = new client.Session.Chart();
chart.setMarket('NYSE:VOO');
var indicator = await TradingView.getIndicator('BearishFlagCP@tv-chart_patterns')
var study = new chart.Study(indicator)
console.log(`Retrieving ${indicator.description}`)
study.onUpdate(() => {
console.log(`Retrieved ${indicator.description}`)
console.log(study.periods)
})Notes:
- chart patterns are not usual pine scripts, not sure if thats relates at all because after end it is still study that is just being rendered
- indicator is searchable even in anonymous session from web site, it just not works for non paid accounts
Wondering if I am missing something, willing to create one more example while have paid subscription, because I bed I am not a first one and not last one who is struggling with this
