只能保证在limit之内不能保证limit之内多少,比如你说我10块钱以下买10股A,市场
上有个人9块卖10股A,front runner可以把那10股A用9块买来,9.99块再卖给你。直接
的big loser是那些需要大量买卖traders和fund managers,间接loser就是百姓的401k
/IRA,但很多时候traders们不care,反正是客户的钱,多点儿少点不影响他们拿bonus
。每个401k的客户也就是亏一点点,但对于dark pool和HFT来说加起来利润就很可观了

| b****w 发帖数: 692 | 5 散户的交易会先到wholesaler手中,whilesaler为了从brokerage house(etrade,
scotttrade, etc)那里竞争客源,会给price improvement, 竞争是很激烈的。Buy
limit order如果价格高于market price, 在wholesaler那里叫做marketable limit
order, 按best offer成交,十有八九是被wholesaler internalize, 不发给exchange.
