灌水, m2c.
1. Longer time period, more useful. example. SPX has broken down 200MA a while. But just broke down 377MA last Friday. 377MA time-frame longer than 200MA, hence more useful (please see the chart attached).
2. 越平越有用. lower slope, more useful. Mathematically, "平", hints, longer time frame.
3. 成交密集区. higher vol previously, more useful. the frozen energy eventually needs release. higher vol, high energy.
I am enclosing a chart of SPX with 377MA and 200MA.
