A momentum signal on Bitcoin's 10-day chart is about to flip positive for the first time in a long while, and history says that is good news for buyers.

• Bitcoin's 10-day momentum reading is pushing above the level that has marked the start of past rallies.
• Every time this has triggered before, Bitcoin generally gained over the following month.
• One month out, about 79% of past cases finished higher, with a typical gain of 14.5% since 2018 and 18.2% across all of Bitcoin's history.
• Stretching out to two and three months, the hit rate climbs to 89% and 95%.
• The only thing that would stop the signal from firing is a sudden, severe crash in the next few days.

Outlook: The signal looks set to trigger this week, pointing to a higher Bitcoin over the next one to three months.
