My answer is: not only is it not necessary, but the two are completely unrelated.
Many traders make market predictions, and I am no exception. Sometimes I am right and sometimes I am wrong. The difference between a novice and an expert is how they deal with a failed prediction. A novice will often lie flat after a failed prediction because they trade based on predictions or emotions, which is unhealthy. Buying and selling criteria should never be based on predictions.
Although market forecasts are based on the perception and judgment of probability, they cannot rise to the level of guiding operations. Operations should be based on the signals of the trading system rather than on forecasts.
For example, if I firmly believe that Bitcoin can rise to $100,000 in this wave, but it turns around after rising to $70,000 and triggers the sell signal of the trading system, what will I do? The answer is: put away the dream first, sell out, and patiently wait for the next buy signal to form a closed trading loop.
You will definitely encounter the kind of perfect transaction that is hard to come by: the buying and selling points of the trading system are surprisingly consistent with the previous predictions, and the buying and selling points are also cleverly located in the relative bottom and top areas of the market. But you must understand that this success is not due to predictions, but because the operation meets the predicted standards.
We are just an operating machine, and operation has nothing to do with prediction. Even if the prediction and operation are consistent occasionally, it is because the prediction meets the standards of the trading system, not because the prediction itself is magical. Operation should be based on rationality and system, not on divine foresight.
