#交易策略误区 A common misconception that many traders often fall into is the trap of 'taking charts and applying strategies.' This means first selecting a classic chart, such as a clearly rising bull market, and then deducing a trading strategy based on this chart. For example, observing that the price steadily rises along the 20-day moving average leads to the conclusion: 'As long as the price breaks above the 20-day line, enter the market; if it falls below, exit the market,' and thus establishing a so-called trading system.

However, the problem with this approach is that you are 'predicting the future.' Because the chart is historical data that has already occurred, formulating a strategy with known results is actually a typical 'future function error'—using future information to influence current decisions, which is fundamentally untenable in actual trading.

A truly effective strategy should be formulated based on statistical advantages, risk control, and objective rules without knowing future trends. Otherwise, no matter how perfect the backtesting may look, it often becomes ineffective in real trading due to market changes and human interference, making it difficult for traders to break through bottlenecks and find a system that truly suits them.
