It is better to have a personal trading strategy, as it will give us a greater chance of success. I always trade using personal trading strategy, it helps us to make right decisions while trading. And it increases the success of trading. For the past few years I have been trading using trading strategies, and I have managed to own a good amount of money. In my opinion everyone should have a personal trading strategy. This will help us to earn good amount of money from trading.
Acquainted with your personal trading strategy, would be difficult at first but as times goes by, it becomes more smooth and convenienable for trader, but I would recommend signals and copy trading for newbies, because this is not something we would just start overnight, we have to plan out our trading strategy to match the market. Ofcourse it's a good to have a personal trading strategy in the space. I study most strategies specifically the ones from pro traders, knows their every move and sometimes follow CPI news.
