Hey Harry,
Welcome to the Academy and the Forum. Yes, I update the EAs from time to time (when it is needed).
And the true valie is the one you see in the file you download. Once, the video is uploaded on YT we can’t really change the content. We can only change the description, so I take advantage of that to update the EA.
You can check this course where I keep the best 10 GOLD EAs I personally trade with:
