You don’t have to only trade one market, but I recommend focusing on a small handful of markets and having one of those that is your favorite. We all know that practice and repetition are the precursors to being wildly successful at anything, and clearly, someone who is a master of the AUDUSD market has practiced in and focused on that market much more than a trader who trades 15 other Forex pairs. In this way, having a favorite market, especially one favorite Forex market, can help you contain your risk.
