NYSE: is it possible for an order NOT to be executed at the open despite its limit being lower than the open?

Question

for instance, if the sell limit order is at 100.17 and the open quote at 100.24, is there any case when the sell order might not be executed (the market falls immediately after quoting...)

Answer 1

In sell limit orders you have to place two prices, the price to start or activate the order and also a price to sell the stock.  So in a sell limit order the stock price could get activated but if the stock blows through the actual price you enter to sell it at then it will never execute until it hits that exact price.  That is one of the pitfalls of a sell limit order.

Answer 2

If the order is on the book at the open, I believe it should get executed at the opening price.  I may be incorrect but that is my understanding.

Answer 3

If you had the sell order in @ 100.17 before the market opened, and if it was a round lot order, you should have gotten an execution if the stock opened at 100.24

If all the 'IFs above were positive, then you can have your broker do a time and sale report for you.
