Yes you can. With our new (as of Feb 2019) Inter-account transfers facility, you can transfer settled funds in your EasyEquities ZAR account into your TFSA account OR your EasyEquities USD account using our EasyFX Rand / Dollar conversion facility (more details HERE). 

You can access the Inter-account transfer or EasyFX functionality from the little stack menu to the left of the EasyEquities log in the top-left of your screen - see highlight in image below.
