I requested to buy a stock about 4 minutes prior to the close of the stock market. I received a partial fill notice before the close and a couple of more notices after the close of the market. Due to what happened the following morning I regret my decision to buy....but non the less I feel that the order should not have been filled after hours and I never would have received the bulk of my buy order. Am I correct in my thinking that once the market closes that should end any trading for the day? Thus my order would be incomplete?
