Common moving averages and how to use them
A moving average smooths out price into a single line, making the underlying trend easier to see at a glance. It's one of the oldest and most widely used indicators, and unlike most indicators, it's directly derived from price itself rather than a complex secondary calculation.
What a moving average actually is
A moving average is simply the average closing price over a set number of recent periods, recalculated and plotted fresh on every new candle. A "50 MA" on a daily chart is the average closing price of the last 50 days, continuously updating.
- A short period MA (like 20 or 50) reacts quickly to recent price — useful for spotting short-term trend direction
- A long period MA (like 100 or 200) moves slowly and reacts to long-term trend — widely watched as a marker of the broader trend
Using a moving average as dynamic support or resistance
In an established uptrend, price often pulls back toward a moving average and bounces off it repeatedly, similar to how it respects a horizontal support level — except the moving average level shifts upward over time instead of staying fixed. In the diagram above, watch how price dips down to touch the faster moving average line and gets bought back up.
Unlike horizontal support, a moving average is support that moves with the trend — which is exactly why traders use it to stay positioned with a trend for longer.
The golden cross and death cross
When a faster moving average crosses above a slower one, it's called a golden cross — widely interpreted as a bullish trend-confirmation signal. When a faster moving average crosses below a slower one, it's called a death cross — interpreted as bearish.
These crosses are lagging signals by nature, since moving averages are built from past price. They confirm a trend that has often already been underway for a while — they're not useful for catching the very start of a move.
Why this matters alongside price action
Moving averages work well as a filter, not a standalone strategy. A common approach: only take long setups (using everything you've already learned about structure and support/resistance) while price is above a key moving average, and only take short setups while price is below it. The moving average tells you the broader context; price action tells you the precise entry.
Key takeaways
- A moving average is the average closing price over a set number of periods, updated continuously
- Shorter period MAs react faster; longer period MAs show the broader, slower trend
- Price often bounces off a moving average in a trend the same way it bounces off horizontal support
- A golden cross (fast MA crosses above slow MA) is a lagging bullish signal; a death cross is the bearish opposite — best used as context, not a standalone entry trigger
