Formula
SMA = Σ(values) / periodsExamples
// price above 20-day SMA (uptrend)
close > sma(close, 20);// volume above 50-day average
volume > sma(volume, 50);// price crossed above 200-day SMA (bullish)
crossover(close, sma(close, 200));// short SMA above long SMA (golden cross)
sma(close, 50) > sma(close, 200);Returns
float — may be NULL
Range
periods must be 2-400
Notes
No value for the first periods-1 bars: NULL until the window holds periods non-NULL values, matching ema()'s lookback for the same period
