A bull trap can indeed be a frustrating experience, especially if you've just witnessed a false recovery. Here are a few ways to potentially identify a bull trap:

1. **Volume Analysis**: During a true bullish reversal, trading volume typically increases significantly. If the price is rising but the volume is low, it may be a bull trap.

2. **Resistance Levels**: If the price approaches and fails to break through a known resistance level multiple times, it could indicate a bull trap.

3. **Divergences**: Technical indicators like the Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD) can show divergences. For example, if the price makes a higher high but the RSI does not, it might signal a potential bull trap.

4. **News and Sentiment**: Sometimes positive news or sentiment can temporarily drive prices up. Be cautious if this uptick is not supported by fundamental changes.
