原版书Volume 5 LM2 Trade Strategy and Execution 课后习题第21题: 不太明白答案解析的这段话：Bradley's target price had been set based on his valuation principles before the opening, whereas waiting for the other benchmarks as inputs would result in the perceived opportunity expiring before it could be exploited. 这个意思是说用其他的benchmark会使得这个其他的benchmark在察觉到的机会在该benchmark出现之前就利用了？这是什么意思，麻烦老师解惑，谢谢！
