Recently, a friend asked me how to use moving averages, and I realized that many people’s understanding of MA settings still stays at a superficial level. In fact, moving averages seem simple, but truly using them well requires a change in mindset.

Let’s first talk about the most easily misunderstood point. Many beginners fill their charts with all kinds of moving averages, adding 5-day, 10-day, 20-day, 50-day, 100-day, and 200-day MA, thinking that this looks very professional. As a result, the signals end up conflicting, and they have no idea which one to focus on. My experience is that more moving averages are not necessarily better; the key is to match them with your own trading cycle. For short-term trading, look at the 5-day or 10-day MA; for swing trading, use the 20-day or 50-day; for long-term trends, watch the 100-day or 200-day. Only then can they truly be effective.

The essence of moving averages is actually very simple: it’s the average cost basis over a certain period. The 5-day MA is the average closing price over the past 5 days; the 20-day MA is the average over the past 20 days. When the price is above the MA and the MA is trending upward, that’s a bullish signal. Conversely, if the price is below the MA and the MA is trending downward, that’s a bearish signal. But this isn’t enough; true experts look at the arrangement of the MAs. When short-term MAs are all above long-term MAs, forming a bullish alignment, that’s when the trend is truly strong.

When I set up MAs myself, I focus on golden crosses and death crosses. When a short-term MA crosses above a long-term MA, that’s a golden cross, usually indicating a rally. Conversely, when a short-term MA crosses below a long-term MA, that’s a death cross, suggesting a potential decline. But be aware, this isn’t 100% accurate because MAs are inherently lagging indicators. They reflect past prices, not future movements.

So my approach is to combine MAs with other indicators. For example, using RSI to see if the market is overbought or oversold, and volume to confirm if a breakout is genuine. When the MA, RSI, and volume all point in the same direction, the probability of success increases. Additionally, MAs can serve as support and resistance levels. In a bullish market, if the price pulls back to the 20-day MA and doesn’t break below, it bounces back—this is a cost basis defense, since most traders’ costs are around this level.

Honestly, the biggest use of MAs isn’t for prediction, but to help you align with the right trend. They tell you where the current market cost is and which way the trend is heading, but they won’t tell you whether it will go up or down tomorrow. I recommend beginners start with just the 20-day and 50-day MAs, find a market with a clear trend, and test a “trend-following pullback” strategy in a demo account for two weeks. You’ll find that MAs are actually much more useful than you think. There’s no perfect indicator—only an ever-optimizing trading system.
