Indicator Overview

The ETF Volume Rate of Change (RoC) is a momentum-based oscillator designed to detect liquidity thrusts within the Bitcoin ETF market. While cumulative volume shows the total size of the wall, the RoC measures the velocity of that wall's growth. It calculates the percentage change in trading volume over a rolling 30-day window, providing a lead indicator for institutional urgency.

By isolating these acceleration points across the Combined ETF complex, the model identifies whether a price trend is gaining structural mass or if the institutional interest is beginning to decelerate.

How To Use

The Volume ROC is best used to confirm the conviction behind price breakouts and to identify macro-regime shifts in institutional participation.

• Zero-Line Crossings (The Momentum Pivot): The dashed grey line at 0% represents the equilibrium point. When the ROC sustains a position above this line, it confirms that the ETF ecosystem is in a state of liquidity expansion. A cross from negative to positive is often the first signal of a new institutional wave.

• Momentum Divergences: If price is making new highs but the Volume ROC is making lower highs, it suggests that the rally is losing its institutional engine. Conversely, a rising ROC while price is flat often precedes an explosive volatility event.

• The 30-Day Velocity: By measuring the ROC over 30 days, the indicator ignores the noise of "quadruple witching" or single-day rebalances, focusing instead on the monthly trend of capital flow.
