SMA 50 tracks the average price over the last 50 periods. It's a common medium-term trend indicator.
Where it fits
The 50-day Simple Moving Average (SMA-50) calculates the arithmetic mean of closing prices over the most recent 50 trading days, representing approximately two and a half months of trading activity. This widely followed intermediate-term indicator is a cornerstone of technical analysis, used to define medium-term trends and generate trading signals when combined with other moving averages.
The calculation:
SMA-50 = Sum of last 50 closing prices / 50
