#加密生态动态追踪 Bitcoin Afternoon Swing Rhythm Analysis (12.13 Update)

On Saturday, $BTC mainly fluctuated within the 90000-90450 range. The framework is quite clear—relying on the upper and lower boundaries of the range for high sell and low buy. Once broken below or above, it’s necessary to decisively adjust the trading strategy.

Key levels to watch: 89843 is the absolute bottom today, having been tested multiple times, with a quick rebound each time. This is a golden point for low buying. If this level cannot hold, then the 90000 integer level becomes the last line of defense. Looking upward, 90617.7 is the highest rebound point; bulls attempted several times to break through but failed, indicating strong resistance.

Trading strategies can be divided into three types:

**Low Buy Window** — When the price falls back to around 90100-89850 and shows signs of stabilization (such as bullish engulfing or hammer candles), small positions can be taken long, targeting 90450-90600.

**High Sell Signal** — When the price rises to the 90450-90600 area, and a resistance-reversal pattern appears (such as bearish engulfing or shooting star candles), consider taking profits or lightly shorting, with a target back to 90100-89850.

**Consolidation and Stalemate** — If the price oscillates around 90300 without a clear direction, it’s better to reduce trading activity and wait for the range boundaries to give clearer signals.

Be cautious of risks: Saturday trading sessions tend to have lower liquidity, making sudden sharp moves more likely. Position sizes should be controlled, and avoid heavy bets. Also, keep an eye on macro news and capital flows, as these can directly break the range balance.
