Moving averages as dynamic support and resistance

Lines that bend with price

Earlier in this track you learned about horizontal support and resistance — flat levels where price has historically reacted. Moving averages are a different flavor: dynamic support and resistance. They aren't flat. They bend and slope with price. In a trend, they often act like a slanted floor or ceiling.

Here's the pattern. In a clean uptrend, price doesn't go straight up. It rises, pulls back, rises, pulls back. Those pullbacks often stop right at a moving average — the 9 EMA in a fast trend, the 20 EMA in a normal swing trend, the 50 SMA in a slower one. Price touches the line, finds buyers, and bounces. That's dynamic support.

The mirror happens in downtrends. Price rallies briefly, fades, rallies, fades — and those failed rallies often top out right at a moving average. That's dynamic resistance. Same line, different role, depending on which side price is on.

Which MA to watch? Match it to the trend speed. Fast intraday trend, look at the 9 or 20 EMA. Daily swing trend, the 20 or 50. Long-term trend on the daily, the 100 or 200. There's no single 'right' line — the right one is the one price is actually respecting.

Recap: in uptrends, MAs act as dynamic support — price pulls back and bounces. In downtrends, MAs act as dynamic resistance — price rallies into them and fades. Watch the MA that price is actually respecting, not the one a book told you to use.
