From the 1-hour chart, BNB is currently at 635, which is slightly oversold as it has fallen below the moving average. The KDJ's J value of -11 has already hit the floor and could rebound at any time.
If it can hold this position without breaking 635, or if a small bullish candle with volume appears, a light position can be taken to bet on a rebound.
Remember to set a stop loss below 634, take some profits and run, don't be greedy.
