In fact, people often think of trading too simply:
It is believed that there are only two directions for trading, bullish and bearish, with a winning rate of 50% each.
But in fact, the two dimensions of time and amplitude are also important.
If you put aside time: it is never wrong to be bullish, it is only too early; it is never wrong to be bearish, it is only too late.
The amplitude is also super important: you may have the right direction, but the wrong amplitude. If the amplitude is too large, you will not be able to close the position but will suffer a loss; if the amplitude is too small and you have to take profit in place, you will either sell off or make a backhand order, resulting in a loss.
So there are actually 64 directions.
From this point of view, the probability that you can get it completely right is less than 2%, which is the difficulty of trading.
