So I caught a post on X. It was an image, a book cover image, and it says, this book will

blow your mind. And the title, technical analysis is mostly bullshit, why flipping a coin is a better

strategy than using technical analysis in the financial stock and 4X markets by Tim Tim Morris. Now that is a title that I can relate to,

for sure. I've not read the book. I don't know Tim. If anyone knows Tim, please have him send me a book.

I'd love to take a look at it. And with that cover alone, I'm sure we can do an interesting

interview. But I replied to the post on X, and I said, predictive or reactive technical analysis.

Now, that's taking me back a long time, because when I was working on my first book that came out in 2004,

the first edition of Trend Following, there was a big issue that I had to write about.

And no one else had ever written about it, which is these two forms of technical analysis.

And I label these two forms predictive and reactive. So that was the

question I asked to this post. And somebody else replied, hey, Grock, please explain the difference.

Fair enough. That makes me realize it's 21 years later and not everybody has learned the same

things that I learned at the same time all those years ago. Time marches on. New people come

along, new generations, and everybody is facing the issue of how do I understand what's real,

what's not real, what's bullshit, what's not bullshit.

So this guy asked for an explanation, an AI explanation of what I met.

And Grok replied, predictive technical analysis aims to forecast future price movements

using patterns, indicators, or models to anticipate

trends or reversals before they haven't. Reactive technical analysis, on the other hand, responds

to confirmed market actions, like entering a trade after a breakout or trend confirmation

without trying to predict. Reactive approaches, such as trend following, emphasize adapting to what the market does rather than guessing.

Hey, that's a fair description. That's essentially what I wrote in my book, Trend Following, the first edition, in 2004.
