Support & Resistance Band

The zone is built from two averages of almost the same length. One is a plain average. The other is exponential, meaning it weights recent prices more heavily, so it reacts faster to a move. The gap between them widens when price is moving quickly and narrows when it is not.

Treating the pair as a zone rather than as two lines crossing is the point. A zone gives price something with width to interact with, and its width tells you how fast the market is moving.

The chart shows price against the two levels that form the band. Trading above it has characterized Bitcoin's rallies; trading below it has characterized its declines.

Which line sits on top also carries information. When the faster-reacting average is above the slower one, recent prices are running ahead of the longer trend.

Both inputs are averages of price and nothing else, so this reads the chart rather than the blockchain. It describes price behavior without reference to what is happening on the network.

During rallies, price has repeatedly fallen back to the band and resumed higher from it without decisively breaking below.

The faster average crossing below the slower one has preceded sharp drawdowns, sometimes by only a few days.

This follows trend, and trend-following indicators produce false signals in flat markets. During long sideways stretches price crosses the band repeatedly in both directions without any crossing marking a real change.

The band is narrow next to Bitcoin's daily swings, so a single volatile day can carry price from one side to the other without anything having actually changed.
