Doing short cycles can't hold big trends; doing long cycles has too large stop-loss and is unbearable.

Wanting the horse to run while also wanting it not to eat grass, it is rare to have a perfect solution in life; every measure has its pros and cons, and the same principle applies to trading.

Short cycles have small stop-loss space, making it easy to control risks, quick to open and close positions, and short holding times; quick and efficient, naturally can't hold big trends.

Doing long cycles can capture big space, but the technical stop-loss space for long cycles is quite large. Once a mistake is made, it results in a significant loss and is very painful.

One method is what we often talk about: look at the big picture and trade small. Identify the trend on a larger scale and find opportunities to enter on a smaller scale. The stop-loss space is small, but after opening a position, you cannot close it based on small cycles; you must aim for the larger profits of the long cycle.
