How to import "indicators" inside AppModule

[yash27]

I want to use Candlestick OHLC Chart with SMA (Simple Moving Average), but SMA comes under Technical Indicator Series and we need to add indicators inside app.module.ts inside imports in require. But how???

This one I tried but doesn't work.

ChartModule.forRoot(require('highcharts/highstock'),require('highcharts/indicators'))
