Trend followers trade the “price”. It’s the number that can’t be faked, the real indicator of the past, now and the future. Richard P. Feynman adds:

“You can know the name of a bird in all the languages of the world [think of all those so-called market fundamentals], but when you’re finished, you’ll know absolutely nothing whatever about the bird…So let’s look at the bird and see what it’s doing — that’s what counts.”

What is the market doing right now? That’s what counts. The price.
