The countless trading traps that #交易策略误区 traders easily fall into: Taking a chart to set a strategy, pulling out a typical market trend chart, and then based on this chart, formulating a trading strategy, establishing your entry signals 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 observe that the price is rising along the 30-day moving average. Therefore, we conclude that the 30-day moving average is effective, indeed very effective, and we use the 30-day moving average as our trading system, entering a position when the price breaks above the 30-day moving average and exiting 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 essentially because you inadvertently introduced a future function, that is, a premise: you already know the future market trend, which impacts 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 market trend and have no idea whether trading strategies based on typical charts can still be applied to the next step in the market's movements. Of course, it is basically impossible because the nature of market trends is constantly changing, and the trading strategies you formulate based on typical charts will quickly lead to losses.
