The metric Spent Output Price Distribution (SOPD), initially developed for UTXO-based blockchains, shows at which prices UTXOs were spent on a given day. The version presented here is a generalization of this concept, which can be applied to account-based chains as well. For more details see our introduction article here. Each bar shows the amount of BTC volume that was moved within that specified price bucket. The price specified on the x-axis refers to the lower bound of that bucket. %-partitioned means that the price buckets are defined by taking the day's closing price and creating 50 equally-spaced buckets each above and below the closing price in steps of +/- 2%.

This is the Point-in-Time (PiT) variant of SOPD (Percent-Partitioned). 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.
