Bitcoin’s Fisher Transform Indicator Signals Rare Bullish Crossover

Bitcoin (BTC) has produced a rare bullish signal on the Fisher Transform indicator, marking only the fourth monthly crossover in the cryptocurrency’s history. Analysts see the signal as a potential confirmation that the latest long‑term floor may be in place.

Monthly Fisher Transform crossover

In August, the Fisher Transform indicator generated a bullish crossover on the monthly chart, the fourth such event recorded for Bitcoin. The crossover occurred in July at a value of –2.26. Historically, similar monthly crossovers have preceded the end of bear markets, including the late‑2022 bottom when the indicator hit –3.83.

Weekly bullish divergence

On the weekly timeframe, the Fisher Transform has been forming a bullish divergence throughout 2026. The indicator reached a swing low of –2.85 at the end of December 2025 while BTC/USD was around $90,000. Since then, the Fisher line has produced higher lows even as price has made lower lows, echoing the pattern observed during the 2022 bear‑market decline.

Context and caveats

While the crossover suggests a possible macro uptrend, analysts caution that price could still consolidate or move lower. Past bull markets have shown bearish Fisher crossovers followed by fresh bullish signals, reflecting the influence of speculative traders on short‑term moves. In contrast, bear‑market bottoms tend to generate cleaner signals due to reduced speculative activity.

Recent price levels

Bitcoin’s 21‑month low near $57,000 on July 1 sparked debate over whether a new cycle bottom had been reached. Recent on‑chain data indicated limited buying interest at those lows, with only a few large‑volume investors accumulating.
