For those with little trading experience or who haven’t developed their own investment system, it’s still recommended to practice your sense of the market (market feel, adaptability). Every time you practice, the money you lose should be the kind that doesn’t make you feel much—this doesn’t depend on a specific ratio but rather on your mindset and the type of market. You’ll lose more in a bull market and less in a bear market. Make sure to differentiate this from regular profit-taking, emotional swings, trend swings, and avoid getting stuck in it. Practicing market feel can also help strengthen your execution skills at the same time.
