Bitcoin Tests Bollinger Bands as Bollinger’s Model Turns Positive

Bitcoin reached the upper Bollinger Band on the daily chart on Wednesday, marking the second daily close above that band since mid-January. Market data show the move followed a period in which the bands recorded their narrowest gap on record the prior month. John Bollinger, the indicator’s creator, confirmed a proprietary trading model at his fund flipped positive and that the fund took a position in Bitcoin; he provided no details on trade size or timing.

Bollinger Bands measure volatility and momentum by plotting lines above and below a moving average. A prolonged narrow band, often called a squeeze, can lead to higher volatility when the bands widen. Traders had flagged the tight bands last month and were watching for daily candle closes as the market tested the upper band.

A trader using the handle SuperBro wrote that the pair “closed above the upper Bollinger Band, above the trendline on closing prices, but just below the log trendline on wicks,” and highlighted several potential rejection points near the upper band. The trader also pointed to a liquidation imbalance, noting relatively few short liquidations remaining up to $85,000 compared with long liquidations down to $74,000, and added that bulls retained a momentum advantage while a clear reversal setup was not visible.

An analytics account under the name Frank Fetter reported a Bollinger-based derivative on the market value to realized value ratio for short-term holders entered what it labels “overheated” territory. That reading last occurred in late 2024, when Bitcoin began a run toward $100,000. The account noted that “overheated” conditions do not necessarily produce an immediate price reversal.

Traders and analysts are monitoring daily candle closes, order-book liquidity and liquidation clusters to assess whether the recent advance can hold or will encounter resistance. Some quantitative models and market participants moved to take long positions after positive signals, while other participants pointed to multiple technical levels where price could be rejected and trigger rapid pullbacks if buyers lose control.
