true_range
True Range (maximum range including gaps)
true_range()
Formula
true_range = GREATEST(high - low, |high - close[1]|, |low - close[1]|)Examples
// current bar range exceeds true range
(high - low) > true_range();// strong volatility expansion
true_range() > sma(true_range(), 14) * 2;// gap up detected
true_range() > (high - low) * 1.5;// use with ATR for normalized volatility
true_range() > atr(14) * 1.5;Returns
float
Notes
GREATEST ignores the single NULL LAG(close) produces on the first bar, so this never returns NULL
