📌 How to use this indicator
- Monitor daily: when 111DMA approaches 2×350DMA, reduce exposure
- The closer they get, the more caution is warranted
- A confirmed crossover has historically marked within 3 days of the cycle ATH
- Note: In the 2021 cycle, it called the April top — but BTC made a new ATH in November 2021 (indicator did not trigger again)
- Not financial advice. Use alongside other indicators.
