Candles and the liquidity line
The candles are the Bitcoin price — red and green, on their real dates. The gold line is the liquidity index. They sit on separate scales, because the point is the shape of each against the other, not their absolute levels. When the two move together, liquidity and the Bitcoin price are aligned; when they diverge, they are not.
Level versus rate of change
The index can be shown as a level or as a rate of change. Levels answer "how much liquidity is there"; the rate of change answers "is it expanding or contracting, and how fast". The relationship between liquidity and the Bitcoin price often lives in the changes, so the rate-of-change view is frequently the more revealing one.
The offset, and measuring
The offset shifts the liquidity line forward against the Bitcoin price. This is a lead-lag view: the value shown at a future date is liquidity measured that many days earlier, not a forecast of the Bitcoin price. Drag across the chart to measure any move in percent, so you can put a number on how far the Bitcoin price ran between two points.
Everything on the chart is real, public data you can verify. Nothing on it predicts the Bitcoin price, and nothing here is financial advice.
