"Three-in-One Trading System | BTC Market Analysis (3/3): Structural Patterns and Core Judgments" --- On the eve of the CPI release, both bulls and bears are gearing up to take each other down. The showdown is about to begin! **Structural Patterns:** 81K is the strong support at the 400-day moving average, while 84.5K is the strong resistance above. BTC is fluctuating within the 80.9K-84.5K range. 81K, where the 400-day moving average lies, has been the bottom line for this pullback, with quick rebounds every time it’s tested. The upper level at 84.5K corresponds to the major cycle Fib 0.618 level, which has shifted from support to resistance. Breaking through will require significant volume. On the daily chart, after BTC surged 42.7% in Q3, there’s selling pressure from profit-taking. The buy-sell depth ratio is only 0.11, with sell orders dominating. Large sell orders around 83.6K are creating resistance. **Little Dragon’s Core Judgment:** On the night before CPI, expect low volume and cautious sentiment. 81K is the bottom line for this pullback—if it holds, BTC will continue to fluctuate within the 80.9K-84.5K range. If it breaks, look for 78K-79K. Tonight’s CPI release will act as a short-term directional catalyst. If the core CPI meets or falls below expectations, BTC might rebound to test 84.5K. If it exceeds expectations, 81K could be tested. Before the data is released, avoid betting on a single direction. Wait for the data to drop and observe the 1-hour close before making a move.
