This question is really hard to answer.
First of all, the most depressing thing is that if a newbie doesn't have any knowledge or experience, he will not be successful in trading even if he has some working trading strategy. It is hard to find a trading strategy which will be efficient in every financial situation. If the situation changes, the trader needs to make his own decisions outside the scope of trading strategy. In this situation a beginner may find himself at a loss and can become depressed. So, a beginner should learn the market and gain experience in order to get used to this whole activity. Only after this step is done, can a trader look for some trading strategy or create his own strategy.
Secondly, money management and risk management are usually not included in trading strategies but these tools are of utmost importance to keep your budget safe. Even if the strategy is very efficient and has the potential to bring lots of profits, market remains unpredictable and you can have losses. The importance of money and risk management boils down to the fact that it doesn't let your budget disappear after several failures. They regulate the size of lot, stop losses and take profits. If you don't know how to set these things in a proper way, your deposit is in great danger.
To cut a long story short, it is better for the beginners to learn the fundamentals and get accustomed to trading. Only after it can a trader concentrate on making decent profits and look for trading strategies.
