Frequently Asked Questions
What is a moving average?
A moving average smooths price data over a specified period to identify trends. The SMA gives equal weight to all prices, while the EMA gives more weight to recent prices, making it more responsive to new information.
What is the difference between SMA and EMA?
SMA calculates the arithmetic mean of prices over a period. EMA applies a weighting multiplier that gives more importance to recent prices, making it react faster to price changes.
Which moving average periods are most common?
Common SMA periods are 20, 50, 100, and 200. The 50-day and 200-day SMAs are widely watched; a golden cross (50 crosses above 200) is considered bullish, and a death cross is bearish.
