[piddubnij]

From manual page: https://php.net/intro.trader

Row:

Extended documentation about indicators, formulas and implementations in other programming languages can be found under » tadoc.org.

Supposed link: ta-lib.org

The link is likely defined in globals.ent in the php/doc-base repo if you want to submit a PR to fix it. :)
