A hard stop is a protective order placed in the market to close a position. Unlike other stops, which traders might move as the stock goes against them, a hard stop is an order that is placed and does not change. This order type is a key component of strict trading plans, where traders honor their initial plan with unwavering devotion. A hard stop order is only executed when a given price level is triggered.
Hard stops are easier to enter as a protective measure, because it is much easier to identify a maximum pain level before entering a trade. However, hard stops are tough to place when a trader is in a winning position. Greed will often lead to a belief that there is always more in a trade. This is why it is important for a trader to place a hard stop to lock in profits.
Below is a chart of the Dow Jones. When the Dow started breaking down in mid-September, it had a 900 point sell off in roughly 4 days to the 10,500 level. There was a quick bounce back up to 11,500 but there was a clear line in the sand at 10,500. A trader would have been smart to place a hard stop order below 10,500 because it would have avoided an additional 25% loss.
