i'm writing a custom indicator: because it uses a Heiken Ashi indicator internally, i need to show the Heiken Ashi on the chart on which my indicator is attached on.
How can it be done using mql4?
You can't do that directly in MQL4. You could create your own heiken ashi buffers inside your custom indicator. Or, use a template which includes your custom indicator and the heiken ashi indicator.
