Notebook 1 p33页Prohibition of all proprietary trading while a firm is in poeeseeion of material nonpublic information may be inappropriate because it may send a signal to the market.(词句中signal意指大概那些市场信号)以及后一句，In these cases, firms should take the contra side of only unsolicited customer trades.整句不太理解这条意思，求教。作者: 334553844 时间: 2015-5-18 15:17
