The reasons are so many, that I have already decided to be like a water flowing, when I see up trend I am trying to flow with it along, and when I see The Fall of Price and trying to be flexible enough to react properly.
The market is always unpredictable so continuous monitoring to make timely investment decisions is very necessary. There is a plan for allocating capital to invest and a plan for the prevention when fluctuations occur, which should be done in the time when the market still has not identified the current trend.
