In fact, many successful forex traders specialize in one or a few specific trading strategies and become experts in those strategies.
The key to mastering a forex strategy is to develop a deep understanding of the underlying principles and to gain experience in applying the strategy in various market conditions. This requires a lot of practice, discipline, and patience.
It's also important to note that mastering a single forex strategy may not be enough to consistently make profits in the forex market. Markets are dynamic and constantly changing, so it's important to stay up-to-date on market trends and be willing to adapt your strategy as needed.
Overall, focusing on mastering a single forex strategy can be a worthwhile approach for traders who are dedicated to putting in the time and effort required to develop expertise in that area.
