Of course, patience is the most important key to success in trading. If you do not have patience for deals, it is better not to start any deal, because any trade needs some time to be completed.
Even in long-term investment, you need patience, because during this long period the price may fall several times, so if you do not have patience, you will sell at a loss.
Some traders who do not have patience do quick scalping deals, but this strategy is dangerous, especially for beginners.
