#数字资产动态追踪 BTC is currently trading at $89,000, fluctuating around that level in recent days, moving up and down repeatedly. The short-term trading strategy is clear—sell high and buy low, wait for a clear breakout at key levels before following through, and avoid blindly chasing.

**Support and Resistance Levels to Watch**

Support levels are at 88,700 (EMA120 line), 87,500 (the dividing line between bulls and bears), and 86,000 (strong support). Resistance levels are at 90,000 (psychological price) and 90,500 (previous high).

**Technical Analysis**

On the daily chart, there are three consecutive long upper shadows, indicating heavy selling pressure around 90,000. The MACD has already crossed bearish, showing overall weakness and sideways volatility. Looking at the 4-hour chart, a double top pattern is very clear, and MACD is also bearish. The price has broken below the EMA120, indicating significant short-term correction pressure. The RSI and KDJ on the 1-4 hour charts are showing signs of turning, but the volume supporting the rebound is insufficient, so caution is needed as the rebound may turn downward again.

**Trading Strategies**

Two approaches:

1. Conservative Long Position: Look for a reversal signal between 87,500 and 88,000 (such as a bullish engulfing or hammer candlestick), enter with a small position, opening 2-3%. Place stop-loss below 87,000. First target at 89,000, then 90,000, taking profits in stages. If the price breaks through, increase to 5% position.

2. Aggressive Short Position: Enter when the rebound from 90,000 to 90,500 is blocked (look for patterns like bearish engulfing or shooting star, with declining volume), opening 1-2%. Strictly stop-loss above 91,000. Target a drop below 89,000, then see if 87,500 can be broken, aiming ultimately for 86,000.

If the breakout is clear—break above 90,500 and the 4-hour candle closes firmly—go long, with a stop-loss back at 90,000, targeting 91,500 to 92,000. If the price breaks below 87,000 and the 4-hour candle closes below, go short, with stop-loss at 87,500, targeting 86,000 to 85,000.

**Risk Management is Priority**

Limit individual losses to within 2% of total capital. Use staged position building and take profits in stages. Never hold full positions, and avoid emotional trading. Stay alert to Fed news; in case of sudden negative news, reduce positions immediately. Short-term trades should be closed on the same day. For trend trading, use EMA120 as a trailing stop.

**Summary**

Today, focus on selling high and buying low within the 87,500 to 90,000 range. The key is whether these two levels can be broken. Breakouts follow the trend; failure to break means sideways movement. Risk control always comes first; technical analysis is just a reference.
