As the word says "buy low and sell high" sounds too easy but the reality of it is that it is very hard to be executed for the fact that knowing when to buy and sell is a challenge already that even long time traders are still having a hard time to put into proper timing. Strategies on trading are easy to be stated but hard to put into action for we are working in a highly volatile market on which time is also an incredible foe to be stated since within a time frame many things can happen. It is up to you on how you will strategize your trading. Just be sure to be familiar on the market you wanted to get into before doing engagement to somehow manage the risk associated with it.
