老师,您好为啥time slicing的缺点是流动性不足也会进行交易,这不应该只是twap的吗?vwap 不是考虑了流动性吗?谢谢

同学你好
VWAP and TWAP algorithms release orders to the market following a time-specified schedule, trading a predetermined number of shares within the specified time interval; for example, trade 5,000 shares between 10:00 a.m. and 1:00 p.m. An advantage of a time slicing strategy is that it ensures the specified number of shares are executed within the specified time period. A disadvantage of a time slicing strategy is that it will force the trades even in times of insufficient liquidity and will not take advantage of increased liquidity conditions when available.
这是原版书的原话,VWAP他确实会在流动性好的时候有利,但是他毕竟也是根据时间切片的,也不是说在流动性差的时段,他还是会执行的。所以只要是时间切片的交易策略,都有这个问题。
