After importing indicator you have to also initialize it like that:

import * as Highcharts from "highcharts/highstock";
import * as Indicators from "highcharts/indicators/indicators";

Indicators(Highcharts); 

I recommend you to use Highcharts Angular official wrapper highcharts-angular. It can be downloaded here: https://github.com/highcharts/highcharts-angular
