#交易策略误区 countless traders easily fall into trading traps: taking a chart to set strategies, taking out a typical market trend chart, and then based on this chart, formulating trading strategies, setting their own entry and exit signals, etc. For example, we find a bullish market trend chart, identify a moving average, such as the 30-day moving average, and see the price rising along the 30-day moving average, thus concluding that the 30-day moving average is effective, really effective. We take the 30-day moving average as our trading system: enter when the price breaks above the 30-day moving average, and exit when it falls below the 30-day moving average. This kind of thought trap can easily confuse countless people, who can never find the root cause of their trading problems.

The reason this logic is flawed is fundamentally because you unintentionally incorporate a future function, namely the premise condition; you already know the future market trend, which affects the formulation of your current trading strategy.

But how can we know the future market trend? It is impossible; the future is always a black hole before us, so we do not know the future trend of the market at all. We fundamentally do not know whether the trading strategy formulated based on a typical chart can still be applied to the next step of the market trend. Of course, it is basically impossible because the nature of market trends is constantly changing. The trading strategy you formulated based on a typical chart will soon fall into a situation of loss.
