A moving average summarizes past prices. Its period changes the question it answers.
Choose what you want to summarize
A simple moving average, or SMA, gives equal weight to observations in its window. An exponential moving average, or EMA, puts more weight on recent observations. Both describe past data. Neither turns a chart into a prediction of the next session.
Set the period in the chart
Add an SMA or EMA overlay and choose its period in the indicator settings. On daily data, a 50-period average refers to 50 daily bars, not 50 calendar days. A longer window summarizes more history and will respond differently to a recent price change.
Compare observations consistently
Look at the relationship between price and the average over time. If you compare two symbols, use the same average type and period. A crossover describes a relationship that occurred; further research is needed to understand the surrounding market and company context.
Carry the condition into a scan
Once the comparison is clear, you can explore a supported moving-average condition in CleverScan. Check the documentation and available history. The Trend Matrix also groups documented average comparisons across multiple horizons, with source values available for inspection.
