Are old trading books still relevant?

The New Market Wizards. Read a bit of it and the concepts discussed flew over my head at the time. I intend to read it a bit later. But there are well known names among the traders interviewed who are worth reading up on. E.g. One of those interviewed, Linda Raschke, is someone I started reading up on and listening to recently. You can always look up books written by those interviewed and those they recommend.

Linda has her own YT channel and was even featured in a BP interview. She’s absolute balls to the wall.

Trading in the Zone, The Disciplined Trader - I don’t think there are a lot of books written by psychologists/psychiatrists. Still as relevant as they were 2 decades ago. Two other authors who write along the same lines are Alexander Elder & Jared Tendler.
