In trading, a trader must have a good understanding of several things. Especially, it is necessary to acquire good skills in market analysis such as fundamental and technical aspects. When a trader acquires good skills in these subjects, he will also be able to create good strategies. Those who want to trade using other people's strategies without having won knowledge. Maybe sometimes that strategy works but not in all cases. If trading strategies worked that way, then those who are ‍selling those strategies would be using for themselves. They would never have tried to sell that trading strategy. No one can be sure in trading. As a trader, I think if someone have good trading knowledge and willing to take risk , then he can get comparatively good results. Trading without knowledge is compared to gambling.
