There are two types of breakouts for #趋势交易策略 — upward and downward:

An upward breakout refers to the stock price breaking above the resistance line, initiating an upward movement.

A downward breakout refers to the stock price breaking below the support line, initiating a downward movement.

The resistance line and support line can be interchangeable:

Once the resistance line is broken, it will turn into a support line.

Once the support line is broken, it will turn into a resistance line.

To determine if a breakout is valid, whether it is a true breakout or a false breakout, you can refer to:

1) Closing price: The closing price must stay above the resistance line (a spike above does not count) and remain stable for three days; if it cannot stay stable for three days, it indicates the breakout is invalid.

2) Price: From the breakout position, there should be at least a 3% increase.

3) Time: After staying above the resistance line, if the stock price returns below the resistance line again, it should not exceed three days; exceeding three days indicates the breakout is invalid and needs to be confirmed again.
