The market trend indeed did not disappoint. The 926-940 range analyzed the day before yesterday has indeed become a key support, and the market dipped to that level yesterday. The most important thing is to react quickly—stop-loss on short positions in time to protect profits. This is the core of trading: prediction is just the foundation, while execution and risk control are the keys to determining victory or defeat. Good analysis tools can help us see the market structure more clearly, but ultimately it still depends on disciplined execution. This round of operations once again verified the importance of stop-loss—better to take a small loss than to hold a position for a large loss. Accurate technical analysis + decisive stop-loss = the foundation of stable returns.
