BTC approximately $85,000, with a 6-hour slight decline judgment. Here are two short-term trading strategies, both with strict risk control, single position not exceeding 5% of total funds, and leverage not exceeding 3x.

Strategy 1: Slightly Bearish in Range (Priority)

- Entry: Rebound to $90,000-$90,500, short position (preferably in batches)
- Stop Loss: $91,200 (if it stabilizes above resistance and signals a bullish turn, exit immediately)
- Take Profit: First target $88,000, break below to $86,500-$87,000
- Logic: 4-hour trendline resistance, cautious before options expiry, rebound lacks strength and may fall back

Strategy 2: Low-Level Long Attempt (Backup)

- Entry: Support at $87,800-$88,000 with stabilization (small bullish candle / decreasing volume to stop decline), light long position
- Stop Loss: $87,200 (if it breaks strong support and accelerates downward, cut losses decisively)
- Take Profit: First target $89,500, second target $90,500 (take profit in stages upon encountering resistance)
- Logic: $88,000 is a key support level in the short term, technical rebound needed

Core Rules

1. Strict stop loss, trigger and close immediately, no holding through losses
2. Build positions in batches, avoid full position, control risk
3. If target not reached / stop loss triggered within 6 hours, exit proactively, avoid fighting the market
4. If breaking above $91,200 or below $87,200, abandon original plan, observe or replan
