TRB is at a critical juncture! The resilience at the 39 support level is evident, with ongoing selling pressure gradually fading, and the signal for a rebound is becoming clearer.

On the four-hour chart, the pullback is showing a clear decrease in volume, with the lows consistently holding above previous lows. The MACD green bars are shortening in tandem, and the energy for a rebound is quietly accumulating. The middle band of the Bollinger Bands provides solid support, with an upward opening expected to warm up.

Operation suggestion: Rely on the 39 support to add to positions, targeting above 41.50, seizing the reversal window.
