Book 6中提到了The opportunistic trading strategy：
“This strategy typically involves using reserve or hidden orders and crossing (internally or externally) to provide additional sources of liquidity at low cost. Because trading is opportunistic, the liquidity strategy is not a true participation strategy.”
这个到底是什么样的一个strategy啊？看不懂哦！！有没有Tx给指点一下呢？谢啦！ |
