That shape is ten years of one company’s price, wound into a coil so the whole thing fits on a screen. Scroll, and we’ll unwind it — one day at a time — until you can read it yourself.

“Zooming out never makes a loss smaller. It just puts more of the story next to it.”
Every dot is one day.
Each weekday the US market opens, people buy and sell, and at 4:00pm New York time there is one last price. That closing price is one dot. Join the dots and you have a chart — that is the entire trick, and you now know it.
Four stretches, four ordinary words.
Here are the last sixty trading days on their own. The line isn’t random scribble — it’s made of stretches, and each one has a plain name you already understand.
The same fall, three times over.
Now watch it coil back up. Sixty days becomes a year; a year becomes ten. The fall you were just staring at shrinks to a nick in the wall — and not one thing about it actually changed.
Now multiply by thousands.
Every listed company is drawing its own line right now, at the same time. One line is a lesson. All of them together is a market — and that is the thing you’re learning to read.

The shape below is ten years of one company’s price, wound into a coil so the whole thing fits on a screen. Unwound, it is 2,520 dots in a row. This page takes it apart.
Every dot is one day.
Each weekday the US market opens, people buy and sell, and at 4:00pm New York time there is one last price. That closing price is one dot. Join the dots and you have a chart — that is the entire trick.
There are about 252 trading days in a year: weekends are closed, and so are roughly nine or ten holidays. So ten years of one company is roughly 2,520 dots — which is why we coiled them up.
Four stretches, four ordinary words.
The line isn’t random scribble. It’s made of stretches, and each one has a plain name you already understand.
- The climb — small ups and downs that add up to a rise. No drama: just slightly more buyers than sellers, most days.
- The quiet — almost nothing happens. Most days in a market are boring, and boring is its normal state.
- The fall — a hard drop over a few days. This is the part that makes beginners quit.
- The jitter — after a fall the line turns jumpy. Jumpiness has a name, volatility, and it means exactly what it looks like.
The same fall, three times over.
Wind those sixty days into a circle and you get one year. Stack ten of those years and you get the coil at the top of this page. The fall you just read shrinks to a nick in the wall — and not one thing about it changed.
