DataType - causes value to be treated as a specific type (price vs. volume)

Date - get the numeric date for a given year, month, day

DateBars - count of bars since (or until) a specific date

DateDay - extract the day number from a date

DateMonth - extract the month number from a date

DateYear - extract the year number from a date

Days - number of calendar days between two dates

DebugEval - stop script execution and log the details of a strategy formula's evaluation when a condition is met

DllDataCalc - call a custom external DLL function to calculate a Data item

Exp - exponential function (e^x)

Extern - evaluate expression for a different stock/contract or strategy

ICDF - inverse cumulative distribution function

IF - conditional branch

InSet - whether a value is in a specific set of values

IsNaN - true if value can't be evaluated, false if it can

Item - refer to a Data or Library item by name

Log - natural logarithm of a number

Logit - inverse logistic function

Max - largest of a group of values

MaxN - Nth largest of a group of values

Min - smallest of a group of values

MinN - Nth smallest of a group of values

MissingBars - number of bars missing before the current bar in this symbol

MostRecent - evaluate expression as of the most recent available bar when one is missing on the current date

NoNan - evaluate an expression with no possibility of a nan (not a number) result

NthOfMonth - whether current bar date is nth specific weekday of current month

OrderSum - evaluates a formula for each non-skipped setup and returns the sum of the values

PositionSum - evaluates a formula for each open position and returns the sum of the values

Random - random number from min to max rounded to step

Reason - return both a value and a string for use in e.g. ExitLimit

Rescale - map a value from one scale to another

Round - round value to nearest step

Select - multi-part conditional branch

SetupSum - evaluates a formula for each setup and returns the sum of the values

Sign - sign of a number (1 or -1)

Sine - trigonometric sine of a number of degrees

SkipNans - evaluate a multi-bar function using only non-NaN values within the lookback period

Sqr - square root of a number

StratRef - find the number of a given strategy, and/or allow dynamic Extern strategy references

Switch - value switch function

SymRef - find the number of a given symbol, and/or allow dynamic Extern symbol references

Tangent - trigonometric tangent of a number of degrees

TanH - hyperbolic tangent of a number

TargetPrice - calculate the value of tomorrow's close that would cause an indicator to reach a specific level
