Because there is no one hundred percent correct strategy in forex. That's why sometimes there are moments where our strategy doesn't work at all. Because indeed the variable as a prerequisite for the strategy did not appear. For example, follow the trend strategy. If the trends that appear are not good or even tend to be sideways, it is clear that the follow-trend strategy will bring disaster. This is natural and natural. Therefore it's good we have a number of strategies that work in a variety of market conditions.
For example, follow the trend strategy when the market is trending well, and scalping strategy when the market is lazy. Other strategies can also be added according to our needs. Just make sure that every strategy we choose has really maximum performance. That must be tested hundreds of hours on the market. Then what if there arises a market condition that we cannot analyze? The answer is yes, don't trade. Consider it a day off.
