Simple Moving Averages (20/50/200)
Education only · our voice · free public data
Definition
A simple moving average is the unweighted mean of closing prices over a fixed lookback window, plotted as a line that smooths price and reveals the underlying trend.
How to read it
Price above a rising MA is bullish context; price below a falling MA is bearish. The 20-day tracks short-term swing structure, the 50-day the intermediate trend, and the 200-day the primary/long-term trend and is a widely watched line for bull/bear regime. Slope matters as much as the crossing: a flat MA implies range/chop, a steeply sloped MA implies a strong trend. Classic crossover events are the 'golden cross' (50 crossing above 200) and 'death cross' (50 crossing below 200).
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
MAs are lagging by construction; in fast reversals the crossover fires well after the turn, so professionals treat them as filters/context, not triggers. Whipsaw is the dominant failure mode in range-bound markets. Multi-timeframe confirmation: use the higher-timeframe 200-day to set bias and a lower-timeframe 20-day to time entries, avoiding counter-trend trades. The 200-day is partly self-fulfilling because so many participants watch it; the reaction to the level can matter more than the level itself. Consider the 200-day 'ribbon' or slope-of-slope to gauge trend acceleration/deceleration.
