The big pie shows a typical oscillation pattern, and in the last hour, a 'bullish engulfing' pattern has formed. The bullish body covers the previous bearish candle, and it appears that the market has stabilized and is starting to rebound. Aggressive friends can go ahead and make a long position, with the first target at 83000.

Support below the big pie is focused on 80036-79956, this level is the dividing line between bulls and bears; breaking below will open up downward space. The resistance above is focused on the previous high of 86416-87106, this position is the previous high resistance zone, and a breakout will require volume support. What we need to pay attention to today is that the current market shows 'low volatility + low volume' consolidation characteristics:

1. MACD and RSI show a bottom divergence signal, but insufficient volume may limit the height of the rebound.

2. The extreme oversold state of KDJ has lasted for 3 cycles, be alert for a technical correction.

3. Pay close attention to the battle for the integer level of 80000; an effective break below will trigger programmatic selling. Below the auntie, focus on 1966-2000, this position is the Fibonacci 50% retracement level + integer level dual defense, while above, pay attention to 2210-2227, this position is a historical dense transaction area. The first target for auntie long positions can be set around 2080.
