The problem is not only luck. But often the problem is in your character. Not everyone is able to wait or make decisions quickly. In addition, trading is quite a nervous activity.
Trading is not all about luck but we will have to true our skills too. In trading, I have seen so many people who lose hope just because they feel unlucky in trading and they stop trading so better believe your skills and keep trading so I am not asking you to chase your losses or lose hope but keep trading with your own new strategies and increased your knowledge as much as you can.
