Hello,
Thanks for contacting us with your question!
You don't need to do calculations manually, because we have an Heikin Ashi chart module.
Just import it (See:
https://github.com/highcharts/highchart ... d-a-module) and set the series type to
heikinashi.
Demo: https://stackblitz.com/edit/highcharts- ... mponent.ts
Let me know if you have any further questions!
Best regards
