In the investment market, some people go all in, investing all their funds, only to see them vanish in an instant amidst the dramatic fluctuations of the contract market. This was evident during the crash of Bitcoin in 2018, when many retail investors failed to cut their losses in time and ended up suffering heavy losses. Good position management acts like a loyal guardian; for example, during the stock market fluctuations in 2020, some investors adopted a staggered entry strategy, effectively controlling risk and protecting their investment portfolios, much like a small boat being guarded from being swallowed by giant waves in a turbulent market. Timing and destiny are closely related, so setting profit-taking and stop-loss points in a timely manner is crucial! There is no need to panic when the market experiences shallow declines; we can gain confidence from previous trend analyses. Just like the recent oil market, the high-pressure rally must inevitably consume the momentum of the bulls, and a technical correction is a normal and healthy market behavior. We should pay attention to the breakout of key levels; for instance, when oil prices break below critical support levels, we should adjust our positions in a timely manner, remain calm, and respond rationally to every market fluctuation. Remember, reasonable position management and calm market analysis are the keys to long-term investment success.
