Currently, there are two scenarios in the market. If it cannot break the rising channel again, the market will fall back to around 4150. A conservative trading approach would be to go long around 4150 if it does not break the level. If it breaks the level, the target would be 4500-4550, and then immediately short around 4550. Over time, the resistance level keeps getting lower. My personal suggestion is that the opportunity for shorting is around 4550, as the trend turns bearish.
