Definition
Moving averages help traders identify trends by filtering out short-term fluctuations. The two most common types are Simple Moving Average (SMA) and Exponential Moving Average (EMA). Common periods include 50-day and 200-day moving averages.
Formula
SMA = (n个周期价格之和) / n
Example
A 50-day SMA adds up the closing prices for the last 50 days and divides by 50. When the price crosses above the moving average, it may signal an uptrend.
