C: The Center of the Range

Halfway between R1 and S1 is a price that more traders watch than any other level on the chart, most of them without knowing why. This book calls it C, for center. This chapter explains why it works before it tells you what to do with it — because a level you understand is one you will trust when the chart is arguing with you.

Why the Middle Matters

Take every trade that happened inside the outer box. Some were buys, some were sells, and they occurred at every price between S1 and R1. Now ask: at what price are those traders, taken together, neither winning nor losing?

The answer is the middle. Above C, the average buyer inside the range is in profit and the average seller is underwater. Below it, the reverse. C is where the range’s participants are collectively even — the price at which the box’s own history is balanced.
