This rebound hasn't ended yet, because breaking below 72839 only destroyed the uptrend within the yellow box. Before breaking below 70273, the uptrend remains intact—it's just that the uptrend has returned to a weak zone. Only when it breaks below 70273, which is the starting point of this rebound rally, will the hourly-level uptrend be completely destroyed, and then it will return to the consolidation zone outlined by the white box below for oscillation.
