Long position on $bnb and Bitcoin, the day Bitcoin opened was too volatile, with too much shaking up and down, so I exited early to avoid emotional swings.

After the first decline of $bnb , there were obvious signs of support, with a rally, sideways consolidation, and then another rally, moving very rhythmically.
When looking at the 5-minute small timeframe showing a bullish candlestick, it was a good time to open a long position.
However, in the overall downtrend of the market, this order can only be opened with the mindset of betting on a rebound.
When the 15-minute timeframe shows increased volume, I should reduce my position or exit.
Next, I consider continuing to short.
Rebounds are only small each time, while the decline seems endless.
