I think this is the basis of your trading strategy. It is the logical basis for making a trading system.

For example, if you think it is an upward trend, then doing more during the callback is a trading idea.

Falling, rebounding and shorting are a trading concept.

In a volatile market, there is not much fluctuation range, and emptying the upper part is a trading concept.

The trading concept also includes: how to stop loss when it is wrong, and how to take profit when it is right.
