This clip comes from the world of Brazilian trading humor, where the line about turning an indicator into a moving average crossover is credited to Dudu in the sound's original description. It circulates online as a short, shareable voice meme passed around trading groups and meme pages, the kind of audio people save to fire back at friends. Its staying power comes from a universal trading experience: fiddling with settings until a simple tool becomes unreadable. Rather than teaching anything, the joke celebrates the moment every trader recognizes their own over-engineering.
