Your stop order would have executed while, in retrospect, that was not what you intended. You can set mental stop orders. When the stock closes below this level you re-evaluate the situation and make a decision about your next step which can be to sell or to move your mental stop to a lower level. If you decide to sell, you would place a market or limit sell order for the next day. If you believe that the stock was pushed down because of general market conditions you could decide to give it some more room.
Mental stops have a serious drawback.
We now have to take large losses the next day. With a mental stop the risk is larger. A stop limit order combines both a stop and a limit order. This type of order specifies both a stop price where the trade is activated and a limit price for which the order is executed. The difference between a stop and a stop limit order is as follows.
