问题如下：
3 To fill the remaining portion of the ABC order, Yellow is using:
选项：
A.an arrival price trading strategy.
a TWAP participation strategy.
a VWAP participation strategy.
解释：
A is correct.
Given the trade urgency of the order, the very liquid market for ABC shares, and the small order size relative to ABC’s expected volume, Yellow is using an arrival price trading strategy that would attempt to execute the remaining shares close to market prices at the time the order is received.
不选B或C是因为有trending吗？
题干中有对剩余订单交易的要求：在订单下好后，使得成交价尽可能接近当前的市场价格。符合这一要求的是arrival price交易策略。所以只能选A。
