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) |
|
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 (more information) | 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) |
