Export custom indicator to CSV

How do I export a custom built indicator (daily basis) to a CSV/Excell file ?

Users guide covers that: http://www.amibroker.com/guide/h_exploration.html and http://www.amibroker.com/guide/h_newanalysis.html (export is covered at the end of the document)

Also there are lots of existing posts about export, just use search: https://forum.amibroker.com/search?q=export

Also knowledge base: http://www.amibroker.com/kb/index.php?s=export

And last but not least Google https://www.google.com/search?q=export+amibroker

As per forum rules you are supposed to search the forum first. Do not start new topic on something that is already covered.
