Calculate any expression across multiple bars of any data series going back in time from the current bar. To start at an earlier bar, use the function()[offset] syntax. Any parameter of a function, as well as the offset (if provided) can be a literal number, a single value, or a formula.
Correl - correlation of two series
CountTrue - count of all bars for which expression was true
DateBars - count of bars since (or until) a specific date
EMA or XAvg - exponential moving average
HMA or HAvg - Hull moving average
Highest or HHV - highest value
KAMA - Kaufman adaptive moving averate
Kurtosis - sample kurtosis
LinReg - linear regression
Lowest or LLV - lowest value
MA or Avg - simple moving average
Median - median of values
Peak - value of nth most recent peak followed by an n% drop (does not look ahead)
PeakBars - count of bars since nth such Peak
PercentRank - percent rank among values
PercentRankN - value with nth percent rank
Product - product of values
Rank - numeric rank among values
RankN - value with nth numeric rank
ROC or PctChg - %gain/loss
RsiF - RSI as a function
SarF - SAR as a function
Sequence - check for a sequence of conditions within a specific number of bars
SinceHigh - bars since highest value
SinceLow - bars since lowest value
SinceTrue - bars since expression was true (0 if now, -1 if never)
Skewness - sample skewness
Slope - slope of linear regression
Spearman - Spearman's Rank Correlation
StdDev - standard deviation
Sum - sum of values
SumSince - sum of values since condition was true
SumSQ - sum of squared values
Trough - value of nth most recent trough followed by an n% rise (does not look ahead)
TroughBars - count of bars since nth such Trough
TrueInRow - count of bars in a row for which expression was true
UntilTrue - bars until expression will be true (0 if now, -1 if never)
WhenTrue - value when expression was true (or will be true if count < 0)
WMA or WAvg - weighted moving average
YInt - y-intercept of linear regression
