In IB, I had a covered call option contract on RMBS that expired in the money. I forgot to close out my position today. I do have 200 shares of the stock long, and this 1 contract short. I went in and placed a GTC close limit order for the stock and the option, but of course its after hours, and I will not get filled till possibly Friday. I can not call IB, since they are closed. Am I right in placing this order to close out the position for both the stock and the option, or will IB automatically close it out for me on Money for example will they close out the long stock and the short option or just the option? Also, if for example, I had instead sold a call option naked, and forgot to close it out, what would happen? My plan was to close the option postion and sell the stock when all time premium had expired, but basically just forgot about the position till it was too late.
