A small tip:

"First determine the trend, then refer to the indicators."

For example, in a downtrend, trying to go long based on oversold indicators can easily lead to a situation of "oversold fatigue" and continued decline.

To be correct, it should be:

1. In a downtrend, look for overbought indicators

2. In an uptrend, look for oversold indicators

3. In a sideways trend, both can be referenced.
