Short Term Holder SOPR (STH-SOPR) is SOPR that takes into account only spent outputs younger than 155 days and serves as an indicator to assess the behaviour of short term investors. For more information see this article.

This is the Point-in-Time (PiT) variant of STH-SOPR. 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.
