To add a moving average (MA) indicator:
- Choose the type of MA: Decide between Simple Moving Average (SMA) or Exponential Moving Average (EMA).
- Select the period: Common periods are 20, 50, or 200 days.
- Calculate the MA:
- SMA: Sum the closing prices over the period and divide by the number of periods.
- EMA: Use a more complex formula that gives more weight to recent prices.
- Plot the MA: Overlay the MA line on your price chart.
