$BTC Breakthrough Strategy: If the 30-minute closing price stabilizes above $107,200, immediately establish a 5% chase position, with a target of $109,800-$111,500. Pullback Defense: A drop below $105,800 triggers a 3% stop-loss order, and place a 2% rebound buy order at $104,500. Hedge Combination: Buy a put option with a strike price of $103,000 (premium accounts for 1.2%), while selling a call option at $110,000 to form a strangle strategy
