SMA (Simple Moving Average)
The arithmetic average of the last N closing prices, recalculated each bar. Moving averages smooth noise so the underlying trend is visible; price above a rising SMA is the simplest definition of an uptrend. Common windows are 20, 50, and 200 days. Crossovers of two SMAs — a fast one crossing a slow one — are among the oldest systematic trading signals.
