这个题能给翻译一下吗

NO.PZ2022061307000013

问题如下:

Question A trader places a limit order to buy shares at a price of $49.94 with the stock trading at a market bid price of $49.49 and the bid–ask spread of 0.7%. The order will most likely be filled at:

选项:

A.$49.94. B.$49.84. C.$49.49.

解释:

Solution

B is correct. An order is filled at the best available price as long as this price is lower than the limit price. In this case, the best available price is the market ask price = $49.49 × (1 + 0.7%) = $49.84. Because this price is lower than the limit price of $49.94, the order will be filled at this price.

A is incorrect. The order limit of $49.94 is larger than the market ask price and accordingly the order will be filled at the market ask price (i.e., $49.84) and not the limit order price.

C is incorrect. The trader can only sell (not buy) at the market bid price. He has to buy at the market ask price.

题干:交易者下达限价单以$49.94的价格购股票,股票以$49.49的市场买入价和0.7%的买卖价差交易。订单很可能在以下位置成交:

市场上的bid也就是买价是49.49

0.7%的bid ask spread可以用来计算市场的卖价:49.49*1.007= 49.84

也就是 bid ask price是 49.49 - 49.84

投资者的买价是49.94>49.84,意思是投资者愿意以49.94的价格买股票,但是实际市场上只卖49.84,所以最后的成交价就是49.84
