Definition. The 30-day change in the supply held in exchange wallets.

Technical. Exchange metrics are based on Glassnode's continually updated set of labeled exchange addresses, together with statistical and data-science methods that are refined over time. The series is therefore mutable: its established history is stable, but recent data points may revise as labels update. For methodology and limitations, see our article on exchange metrics and Exchange Data Transparency Notice.

Interpretation. Negative prints reflect a 30-day window of net outflows from exchange-tagged addresses, positive prints reflect a 30-day window of net inflows.

This is the Point-in-Time (PiT) variant of Exchange Net Position Change. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
