Core purpose and essential characteristics of washing, six classic washing patterns and recognition points, key signals for the end of washing and buying timing, market characteristics and behavioral logic of main force washing, avoidance of washing traps and operational discipline, etc. Below is a brief overview of these core contents:

1. Core Purpose and Essential Characteristics of Washing:
Core Purpose: Washing is to prepare for subsequent rises in coin price by clearing floating chips to raise the average market cost and test the strength of control.

Common Features: Shrinking trading volume, key support not breaking, technical indicators not deteriorating, controllable amplitude.

Essential Logic: The main force creates panic to clean up retail investors' chips, but their own positions remain stable, resulting in reduced volume, stable price, and strong indicator resilience.

2. Six Classic Wash Patterns and Recognition Points:
Continuous Small Bearish Candles: Continuous small bearish candles when the coin price is sideways, with continuously shrinking trading volume, usually occurring at the midway point after the first wave of surge, the buying point is the bullish engulfing or a breakout of the sideways platform with increased volume.

Aerial Refueling: After the first wave of rapid rise, a large bearish candle pullback, a shrinking doji stabilizes, and a breakout of the previous high with increased volume. The buying point is the breakout of the bearish candle high after the doji.

Wedge Wash: Descending wedge, narrowing amplitude, decreasing trading volume, creating a false 'breakdown' illusion. The buying point is a breakout of the wedge upper track with increased volume or a confirmation of a pullback to the upper track with reduced volume.

Shadow Line Wash: Long upper shadow or long lower shadow, with the shadow appearing above the 60-day moving average. The buying point is the next day's high opening or a quick engulfing of the shadow high point within half an hour.

Platform Breakdown Wash: After a narrow sideways trading of the coin price, a sudden large bearish candle breaks down, and a quick recovery the next day. The buying point is the recovery of the platform within 3 days after the breakdown.

Strong Wash: A single day of a large bearish candle but with volume far exceeding normal, a bullish engulfing the next day. The buying point is a breakout of the consolidation platform with an increased bullish candle.

Best Buying Point Summary: Continuous small bearish candles followed by a bullish engulfing, aerial refueling breaking the high of a large bearish candle, wedge wash breaking out of the upper track with increased volume, shadow line wash quickly engulfing intraday, platform breakdown wash recovering within 3 days, strong wash breaking out of the consolidation platform with increased bullish volume.

3. Key Signals for the End of Wash and Buying Timing:
Volume-Price Coordination Signal: Volume decreases to below 70% of pre-activation levels, a bullish candle breaks out of the consolidation platform.

Market Language Implications: Selling pressure in five levels but the coin price does not drop, buy orders appear in special combinations like 333, 555, 888.

Sector Linkage Verification: Individual coins resist declines, or leading coins turn positive first.

4. Market Characteristics and Behavioral Logic of Main Force Washing
Order Traps: Large sell orders in five levels create a false selling pressure, while concentrated small buy orders hold the bottom without actively buying.

Cross-Trading Manipulation: The main force buys and sells to create a false increase in volume, while actual chips are not lost.

Emotional Manipulation: Using negative news to amplify panic or reacting coldly to positive news.

Main Force Mindset: Washing is not truly about falling, but making retail investors feel it will fall.

5. Avoiding Wash Traps and Operational Discipline:
Beware of False Wash and Real Selling: High-volume stagnation at high positions, turnover rate greater than 20%, breaking key platforms and not recovering within 3 days.

Strict Position Control and Stop Loss: Initial exploratory positions should not exceed 30%, increase positions after breakout confirmation, and set stop loss 3% below the lowest point of the wash pattern.

Reject Emotional Trading: Do not panic sell due to long bearish candles, and do not intervene too early in low-volume sideways trading.

6. Ultimate Summary: 'Three Do's and Three Don'ts' of Wash Patterns:

Position Judgment: Only engage in mid-low position washes, beware of high position volume 'washes'.

Volume Verification: Decreasing volume plus breakout with increased volume are both essential; ignoring volume coordination leads to blind bottom fishing.

Signal Confirmation: Add positions after a breakout and a solid pullback, do not chase after a single K-line for bullish or bearish trends, avoid hasty buying.

Mnemonic Reminder: Washing will eventually end, low volume is a sign of self-awareness, breaking out with volume is a rise, and riding the wave is the main ascent.
