I will respond to your inquiry based on the information available in the sources you provided.
The sources mention that there are key indicators expected to support the $400 area for BNB price. These indicators include:
* **200-week moving average**.
* **Fibonacci retracement level 0.618** which is measured from the lowest and highest points of a recent price movement.
* **A visible liquidity pocket that has not yet been utilized**.
The sources indicate that these three indicators together create a "strong attraction for price movement" towards the $400 area. If the price reaches this area, it will complete a "healthy test of the lower channel", paving the way for the start of a sustainable bullish trend.
Structurally, the pullback to the $400 level "will not negate the bullish trend but may reinforce it". A rise again from this level will strengthen the market structure and provide a launch point towards the upper limit of the price channel at the $800 level. This could mean doubling the value of BNB from this area, offering an attractive scenario for traders and long-term investors in terms of risk-return relationship.
