The price of Bitcoin (BTC) has fallen below the support level of 90,000 USD again over the weekend, as increased volatility continues to dictate trading conditions this December.
Many traders point out a pattern called Bart Simpson, which repeatedly appears on the Bitcoin price chart. Currently, there are signals that this pattern is emerging once again and may define the price movement in the coming days.
Bart Simpson pattern: influence and resurgence in December
The Bart Simpson pattern is named after the famous cartoon character Bart Simpson due to its shape resembling his hairstyle, occurring when Bitcoin moves sharply in either direction, whether up or down, within a short period.
After that, prices will stop and move within a horizontal range before the market quickly returns to previous price levels. Although the name sounds funny, this pattern represents a real challenge for players in a highly volatile market.
Several traders recorded the recurrence of this pattern last month. Some analysts shared graphs showing three patterns found between December 10-12, while other observers pointed out five cases and more during late November to mid-December.
Considering this situation, one analyst suggests that Bitcoin may be forming the Bart pattern again. If confirmed, this pattern could lead to another upward movement.
However, the sustainability of the upward adjustment still needs to be monitored, with analysts adding that if there is a breakout followed by a reversal, it is a scenario that could occur.
Bart pattern + weekend order book = a trap for stop losses. For me, both sides will be completely swept before a clear direction is seen. Sunday or Monday is not just a prediction, but more of a liquidity event, said Paweł Łaskarzewski.
Liquidity and market mechanics
Meanwhile, one analyst also noted that the Bart pattern is not new and has occurred repeatedly throughout Bitcoin's trading history.
According to analysts, this pattern often appears in specific market conditions, particularly when liquidity is thin. They also add that these patterns often occur alongside activities from major players in the market.
At the same time, retail traders will start chasing momentum after prices experience sudden volatility, while stop-loss levels become clearly visible as well.
Prices spike during low liquidity. Everyone starts tweeting their targets, confidence returns... then the price immediately drops back down and retraces completely. Many continue to argue that this is a 'natural price discovery,' even though the chart looks like it was drawn with a ruler. Whether you love or hate Bart, he never misses. This post notes that.
However, another analyst suggests that the frequently repeating Bart pattern often acts as a short-term volatility trap, where sudden price movements can trigger rapid reversals, and short-term traders must exit positions abruptly when momentum fades.
The Bart pattern is meant to make traders feel emotionally exhausted, while long-term holders hardly notice these movements at all, market observers added.
Therefore, while Bitcoin is still trading in a rapidly responsive environment, the repeatedly appearing Bart pattern highlights the role of liquidity and market structure on short-term price behavior. Even though these patterns lead to sharp movements or rapid reversals, analysts point out that their impact is often limited to short-term positioning, while the broader trend direction depends on liquidity and sustained participation.
