an ELD won't help him. ELA is the format Tradestation used for indicators in TS 4.0. The successor TS 2000i introduced the ELS format then and today's versions use ELD files. While you can import an ELA file into Tradestation 9.1 the other way around is impossible.
@theklingman as TS 4.0 is rarely used today the best way would be for you to create the code yourself. After all Donchian Channels don't require too much coding.
