Trend following with moving averages

Trend following is built on a simple bet: once a trend is established, it's more likely to continue than reverse, so the goal is joining it as early as reasonably possible and riding it for as long as it lasts, rather than trying to guess the exact top or bottom.

The classic tool is the moving average — a line that smooths out price into its average value over a set number of candles, updating as new candles form. A fast moving average (like a 20-period) reacts quickly to recent price; a slow one (like a 200-period) moves gradually and represents the bigger picture.

The most well-known signal is the crossover: when a fast moving average crosses above a slow one, that's read as a fresh uptrend starting (sometimes called a "Golden Cross" when it's the 50 crossing above the 200); the opposite crossover downward is read as a new downtrend (a "Death Cross"). Traders following this approach look to buy on bullish crossovers and sell on bearish ones.

Moving averages also work as dynamic support and resistance in an established trend — in a strong uptrend, price often pulls back to touch a moving average and bounce, giving trend-followers a lower-risk entry than chasing a fresh breakout.

The honest weakness: moving averages lag, by definition, since they're built from past price. In a genuinely trending market they work beautifully; in a choppy, range-bound market they generate a frustrating string of false signals, whipsawing back and forth. Knowing which type of market you're in — straight back to Module 3's trend-vs-range lesson — decides whether this strategy is even appropriate right now.
