Moving averages smooth price over time. They help you see trend direction without reacting to every tick.
Simple vs exponential
A simple moving average (SMA) weights each period equally. A 20 period SMA is the average close of the last 20 bars.
An exponential moving average (EMA) weights recent prices more heavily. It reacts faster to new information.
Neither is universally better. Faster averages generate more signals and more noise. Slower averages lag but filter chop.
Common uses
Trend filter: Price above a rising 50 or 200 period average often describes an uptrend on daily charts.
Dynamic support: In strong trends, pullbacks to a 20 EMA on an hourly chart sometimes resume the move.
Crossovers: A short average crossing above a long average is a classic long signal. Crossovers work best in trending markets and struggle in ranges.
Nordic equity context
Index heavy names like Novo Nordisk or Ericsson can respect long averages on daily charts for months. Small cap OMX names may slice through averages on thin volume. Match the average length to the timeframe you actually trade.
Caution
Averages describe the past. They do not predict news, earnings gaps, or policy shocks. Pair them with stops and position sizing.
