#交易策略误区 countless traders easily fall into trading traps: taking a chart to formulate strategies, taking out a typical market trend chart, and then based on this chart, developing trading strategies, setting their entry and exit signals, etc. For example, if we find a bull market trend chart, we look for a moving average, such as the 30-day moving average, and the price rises along the 30-day moving average. Thus, we conclude that the 30-day moving average works, it really works, and we use the 30-day moving average as our trading system, entering the market when we break the 30-day moving average and exiting when we drop below it. This kind of thinking trap can easily confuse countless people, who always fail to identify the root cause of their trading problems.

The reason this logic is incorrect is essentially because you inadvertently include a future function, that is, a premise condition; you already know the future market trend, which affects the formulation of the current trading strategy.
