Consider the following scenario. A customer owns 100 shares of TUV corp stock. The stock closed at $56.44 for the day. The customer had entered a Good Til Cancel order earlier in the day, to sell 100 shares at a limit price of $56.91. The order continues working after the close. The next day TUV opens at $55.60 and goes down the rest of the day. The high of the day was $55.60. What happened to the customer's order?
