Moving Averages (21dma-structure)
As an intermediate-term swing trader, the 21-day moving average is the backbone of my system. Over time, I’ve simplified my approach to the point where this is really the only indicator I keep on my charts — aside from a few key lines to help define structure and pivots.
To give that moving average more context and flexibility, I use a 21-day EMA structure, built from the lows, highs, and closing prices. This creates a dynamic zone — not just a single line — that helps me visualize trend, momentum, and risk. It gives enough room for natural volatility, while still keeping me anchored to the trend.
Everything I do — from entry to trimming to holding — revolves around this structure. When price is above it, I lean in. When it’s below and declining, I stay out or manage risk tighter. Simple, clean, and consistent.
