Operators - Arithmetic, Relational, Logical
| Arithmetic | Description | Example |
| + | Addition | HI + LO + CL |
| - | Subtraction | MA - CL |
| * | Multiplication | (CL * 2 + MA * 3) / 5 |
| / | Division | (HI + LO + CL) / 3 |
| % | Remainder operator. X % Y results in the remainder of X / Y. For instance, 10%3 = 1. | ((CL*100)% 100) / 100 |
| ^ | Power | CL ^ 6 |
| ABS(exp) | Absolute Value | ABS(CL) |
| ACOS(exp) | Arc Cosine | ACOS(exp) |
| ASIN(exp) | Arc Sine | ASIN(exp) |
| ATAN | Arc Tangent | ATAN(exp) |
| AVG(exp, n) | Average of expression over last n periods. | AVG(HI, 12) |
| COS(exp) | Cosine | COS(exp) |
| HCOS(exp) | Hyperbolic Cosine | HCOS(exp) |
| HSIN(exp) | Hyperbolic Sine | HSIN(exp) |
| HTAN(exp) | Hyperbolic Tangent | HTAN(exp) |
| IF(expA) THEN(expB) ELSE(expC) | Conditional IF-THEN-ELSE statement. If expA is TRUE, then expB is executed, else expC is executed. | IF(CL > MA) THEN (SET(V#1, CL)) ELSE (SET(V#1, MA)) |
| INT(exp) | Integer operator. Truncates the expression to a whole number. | INT(MA) INT(29.97) = 29 |
| LOG(exp) | Exponential Logarithm (base e) of expression. | LOG(CL) |
| LOGT(exp) | Base 10 logarithm of expression value | LOGT(CL) |
| MAX(exp, n) | Maximum value of expression over last n periods. | MAX(HI, 20) |
| MIN(exp, n) | Minimum value of expression over last n periods. | MIN(LO, 30) |
| PNZ(exp) | Returns +1, -1, or 0 corresponding to whether the expression is positive, negative, or zero. | PNZ(MACD) |
| RAND(n, m) | Random whole number generator. Generates a random whole number between n and m. | RAND(0, 100) / 100 |
| ROU(exp, n) | Rounding operator. Rounds the expression off to the nearest multiple of n. | ROU(CL, 0.1) ROU(12.51, 1) = 13 |
| SET(property, exp) | Sets the value of property to expression. Property can be any V# variable, the highlight color, etc. | SET(V#1, CL - OP) |
| SHOW(exp) | Show the value of expression. This is used for reporting purposes in backtests. | SHOW(FASTD) |
| SIN(exp) | Sine | SIN(exp) |
| SMAX(expA, expB) | Scalar Maximum. Result is the maximum of the two expressions. | SMAX(CL, OP) |
| SMIN(expA, expB) | Scalar Minimum. Result is the minimum of the two expressions. | SMIN(CL, OP) |
| SQRT(exp) | Square root of expression. | SQRT(CL) |
| STD(exp, n) | Standard Deviation of expression over last n periods. | STD(CL, 13) |
| STDN(exp, n) | Standard Deviation of expression over last n periods using n - 1 as divisor | STDN(CL, 13) |
| SUM(exp, n) | Sum of expression over last n periods | SUM(VO, 20) / 20 |
| TAN(exp) | Tangent | TAN(exp) |
| Relational | Description | Example |
| < | less than | HI > MA |
| <= | less than or equal to | OP <= CL |
| = | equal to | MA = MA1 |
| != | not equal to | HI != HI2 |
| > | greater than | LO > LO3 |
| >= | greater than or equal to | MA3 >= HI |
| ? | conditional expression | CL > OP? HI: LO |
| Logical | Description | Example |
| AND | Both operands must be true in order for the result to be true. | (HI > MA) AND (CL > OP) |
| OR | If either operand is true, or if both are true, then the result is true | (HI > MA) AND (CL > OP) |
| NOT ! |
The NOT operator reverses the value of the expression that follows. NOT X is TRUE only if X is FALSE. | NOT (MA > OP) !(MA > OP) |
