The current coin price has validly fallen below the “long-short channel,” and the market structure has confirmed a bearish-led pattern.

The current medium-term short position will temporarily be kept at around 20%.
If the coin price rebounds to the $65,700~$67,300 area and shows signs of stalling, and combined with the top signal from your custom quantitative model, you may consider increasing the medium-term short position to within 50%.

2 short-term strategies:
Using a 30% position, set a stop-loss point; based on support and resistance levels, look for a “spread” opportunity. (Use 30-minute/60-minute charts as the trading cycle)

3 In short-term trading, to dynamically respond to the market’s complex evolution, we have prepared two specific A/B operational scenarios in advance.

Scenario A: test short positions in a strong resistance zone
Open: If the coin price rebounds to the $65,700~$67,300 area and meets resistance, and combined with the top signal from the quantitative model, you can establish a short position of around 30%.
Risk control: set an initial stop-loss level.
Close: When it adjusts near an important support level and combined with the quantitative model signal, you can gradually close positions to realize profits.

Scenario B: light long positions in a strong support zone
Open: After the coin price rebounds to the $65,700~$67,300 area, meets resistance, and pulls back. If, while adjusting above the previous low of $57,820, there appears a stop-and-recover/stabilization signal, and combined with the bottom signal from the quantitative model, you can establish a long position of around 30%.
Risk control: set an initial stop-loss level.
Close: When the rebound reaches near an important resistance level and combined with the model signal, you can gradually close positions to realize profits.
