Functions

Function Type	Purpose
Math functions	To perform math operations like addition, subtraction, standard deviation, etc.
Logical functions	To perform conditional math.
Study functions	To perform common technical analyses.
Cyber Chart functions	To perform common technical analyses.
Quote Functions	To assist in displaying formula results in quote windows.

You use functions to build mathematical expressions. The simplest application of a function is to perform a mathematical operation on a data series. For example, in the following formula,

SQRT(IBM)

The program calculates the square root of IBM’s last prices.

You can also perform mathematical calculations on the results of a mathematical operation. For example, in the following formula,

savg(ibm.high,10)-savg(ibm.low,10)

The program subtracts a simple moving average of IBM’s low price from a simple moving average of IBM’s high price.

Additionally, you can perform “second-order” calculations. An example of a second order calculation is a simple moving average of a simple moving average, as illustrated in the following formula:

savg(savg(ibm,10),5)

Here, the program calculates a five period simple moving average on a ten period simple moving average of IBM’s last price. Using second-order calculation, you can compute a moving average over half a MESA dominant cycle:

savg(ibm,mdomcycle(ibm)*0.5)
