After RIVER broke below the support level on the bearish belt hold, the short-term rebound space is limited. From a technical perspective, the rebound reaching around 5.2 is a better position to get on board for short positions. Looking at the recent trend, this price level is clearly under pressure, with a higher probability of breaking down. It is recommended to set open orders at 5.2 to execute the short strategy, with a stop loss set at 5.4. Under controllable risk conditions, the idea of counter-trend short during the rebound is worth following.
