AFL Reference Manual
Introduction
AFL is a special programming language used to define and create custom indicators, scans, explorations, back-tests and guru commentaries.
Basics
Lexical elements
This chapter describes the different categories of word-like units (tokens) recognized by the AFL language interpreter.
Whitespace
Whitespace is the collective name given to spaces (blanks), tabs, new line characters and comments. Whitespace can serve to indicate where tokens start and end, but beyond this function, any surplus whitespace is discarded.
Comments
Comments are pieces of text used to annotate a program. Comments are for the programmer's use only; they are stripped from the source code before parsing. The are two ways to delineate comments: C-like comments and C++ like comments. A C-like comment is any sequence of characters placed after the symbol pair /*. The comment terminates at the first occurrence of the pair */ following the initial /*. The entire sequence, including the four comment-delimiter symbols, is replaced by one space. A C++ like comments are single-line comments that start by using two adjacent slashes (//) in any position within the line and extend until the next new line.
AFL does not allow nested comments.
Tokens
AFL recognizes five classes of tokens:
identifiers
constants
string-literals
operators
punctuators (also known as separators)
Identifiers are arbitrary names of any length given to functions and variables. Identifiers can contain the letters (a-z, A-Z), the underscore character ("_"), and the digits (0-9). The first character must be a letter.
AFL identifiers are NOT case sensitive.
Constants are tokens representing fixed numeric or character values. Numeric constants consist of decimal integer and optionally: decimal point and decimal fraction part. Negative numeric constants have unary minus (-) prefixed.
String constants, also known as string literals, form a special category of constants used to handle fixed sequences of characters and are written as a sequence of any number of characters surrounded by double quotes:
"
This is literally a string"
The null (empty) string is written "". The characters inside the double quotes can include escape sequences ("\n" - a new line escape sequence).
A Constant expression is an expression that always evaluates to a constant. They are evaluated just as regular expressions are.
Punctuator (also known as separator) in AFL is one of the following characters:
( ) , ; = .
Parentheses (open ( and close ) ) group expressions, isolate conditional expressions and indicate function calls and function parameters:
d = c * ( a + b ) /* override normal precedence */
a= (b AND c) OR (d AND e) /* conditional expression */
func() /* function call no arguments */
The comma (,) separates the elements of a function argument list
The semicolon (;) is a statement terminator. Any legal AFL expression followed by a semicolon is interpreted as a statement, known as expression statement. The expression is evaluated and its value
is discarded (except Guru Commentaries where string values are written to output window)
The dot (.) is a member access operator. It is used to call COM object methods. If myobj variable holds the object, using dot operator we can call the methods (functions) of myobj object:
myobj.Method();
The equal sign (=) separates variable declarations from initialization lists:
x = 5;
It also indicates the default value for a parameter (see built-in function description):
macd( fast = 12; slow = 26 ) /* default values for fast and slow arguments)
Language structure
Each formula in AFL contains of one or more expression statements. Each statement MUST be terminated by semicolon (;). In this way you are able to break long expressions into several physical lines (in order to gain clarity) and AmiBroker will still treat it like a single statement until terminating semicolon. Examples:
Answer:
These things do not affect the direction of the inequality: Add (or subtract) a number from both sides. Multiply (or divide) both sides by a positive number. Simplify a side.
