This position was originally a radical trade, and after a night of movement, it’s very awkward to be stuck without going up or down, and the profit margin has been worn down. It is necessary to reduce positions at highs and wait for clear signals before trading again. This kind of movement is also not suitable for short-term trading. Although it has been fluctuating between 4360-4270 since last night, with about 100 points up and down, it is very difficult to fully grasp this rhythm while also having a defensive strategy. The fluctuations these past few days have been almost all catchable, but the current movement is really not suitable for trading.
