Patience always plays a key role in trading. Those traders who can't understand the volatile situation of the market will often complain and say they are losing. That is why trading is not meant for everyone, knowing that not all are also willing to wait and take extra effort to analyze the market situation. At the end of the day, it was not the market we were going to blame for our losses, but ourselves. If we are not going to learn from our mistakes and find a way to improve, it is useless to be here trading because that won't change the outcomes.
There is a popular saying that "the .market punishes those who are impatient and reward those who are patient" This statement summarises the importance of patience in trading. You must be patient for the price to get to your entry point and after your orders are filled, you must be patient to allow the market do it's thing. If you are not patient, you can even abandon a winning strategy or even close a winning trade thereby missing out on the bigger profits.
