| Why do options bid and ask vary after hours when the options market is suppose to be
closed? I have had situations where my orders executed after the close of business, yet I can't place new orders in after COB.
People keep on talking about the international market, but if you buy an option in the CBOE and they close at 4PM EST then the trading has to stop, yet it doesn't. If an ordinary investor can't make order after this point then who is and why is it legal? This only happens for ~15minutes after close, but should it happen at all?
