The Difficulty Ribbon is an indicator that uses simple moving averages (200d, 128d, 90d, 60d, 40d, 25d, 14d) of the Bitcoin mining difficulty to create the ribbon. Historically, periods when the ribbon compresses have been good buying opportunities. The Difficulty Ribbon was created by Willy Woo. For more information read this article.

This is the Point-in-Time (PiT) variant of Difficulty Ribbon. 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.
