Don’t let your losses grow too large.
Nobody likes to take a loss, but failing to take a small loss early will often result in being forced to take a large loss later.
A great trader is not someone who has never had a loss. Great traders have made many losses.
Every trader needs to develop a method for getting out of losing trades quickly. The most prudent thing to do is to plan your trading strategy before the market opens and then strictly stick to it during trading hours.
Cut your losses without sinking in it, that's the only way to win in a falling market.
Good luck and safe trading
