From the 8-hour chart, there are several key points in the market trend that need to be noted:

1. The current price position with Bollinger Bands

Bollinger Bands:
The current price (3414.80) is close to the lower band of the Bollinger Bands (3343.33). This indicates that the price may be in a short-term oversold area, with some technical possibility of a rebound.

Pressure and Support:

Upper resistance level: The middle track of the Bollinger Bands (3770.29) will be the first target for short-term rebound.

Support below: the lower Bollinger Band (3343.33) and the recent low point (around 3200-3300) form a key support area.

2. MACD Indicator

Current Status:
The MACD histogram continues to be in the negative zone, and the DIF and DEA lines are diverging downwards, indicating that the market is still in a downtrend with bearish dominance.

Signal judgment:
If the subsequent histogram shows signs of narrowing, it may indicate a weakening of bearish momentum and the possibility of a rebound.

3. KDJ indicator

Current Status:
The K value, D value, and J value of the KDJ indicator are all in the oversold zone (K value 26.23, D value 22.31, J value 34.06), indicating the market has the potential for a short-term rebound.

Important points:
If the K value breaks above the D value to form a golden cross, it will be a short-term buying signal.

4. Comprehensive Analysis

1. Short-term trend:

There is a demand for a short-term market rebound, which may test the midline of the Bollinger Bands (around 3750). However, if it fails to break through the midline, the rebound may be limited.

2. Medium-term Trend:

The downward trend has not yet reversed. If the price falls below the support level of 3340, it may further test the 3200 or even 3000 area.

Today's strategy recommendation

1. Aggressive investors:

You can try a light position long in the 3350-3400 area, with a target to 3700, and a stop loss set below 3300.

2. Conservative Investor:

Wait for the price to stabilize around the middle Bollinger Band (around 3750) before considering setting up long positions after confirming the rebound trend.

3. Risk Control:

The current downtrend is strong, it is not suitable for heavy positions, closely watch the market sentiment and the performance of key support levels.

Be cautious in operation and adjust your strategy flexibly!
