Suppose you have a formula that calculates a percentage:
percentage(numerator,denominator)=abs((numerator/denominator)*100)
In an alarm, you can call this formula.

if percentage(IBM.open,IBM.last)>2 |
IBM has moved more than 2%, up or down |
System functions are built-in functions, and you can use them in alarm expressions.
