APPL 1.0
Documentation
APPL (Avasaram Platform Programming Language) is
a powerful language used to extend the built in functionalities of the Avasaram
platform. It could be used to create advanced filters and advanced
display columns. Language syntax for APPL is very similar to the
popular language JAVA.
APPL scripts must start with a curly brace ”{”
and end with a curly brace “}”. All the statements in the script must
end with a semicolon “;”.
A sample script for APPL filters to find stocks
with last traded price greater than 10.
{
stock.getLast() > 10;
}
A sample script to add an APPL display column of
maximum return probability.
{
strategy.getMaxReturnProbability();
}
APPL Core Objects and Classes
|
Object/Class
|
Description
|
|
strategy
|
The
strategy object which contains information about the strategy being accessed.
Example to get the ticker
symbol of the underlying stock.
strategy.getTicker()
|
|
stock
|
The
underlying object for the strategy.
Example to get the last
traded price.
stock.getLast()
|
|
longLegOne
|
The first
long leg associated with the strategy. In case of a married put strategy this
is the put option purchased to protect the stock. Presence of this object
depends on the strategy that is being accessed.
Example to get the option
symbol.
longLegOne.getOptionSymbol()
|
|
shortLegOne
|
The first
short leg associated with the strategy. In case of a covered call strategy
this is the call option sold against the stock. Presence of this object
depends on the strategy that is being accessed.
Example to get the option
symbol.
shortLegOne.getOptionSymbol()
|
|
longLegTwo
|
The
second long leg associated with the strategy. Presence of this object
depends on the strategy that is being accessed. This is usually present in a
multi leg strategy like butterflies and condors.
Example to get the option
symbol.
shortLegOne.getOptionSymbol()
|
|
shortLegTwo
|
The
second short leg associated with the strategy. Presence of this object
depends on the strategy that is being accessed. This is usually present in a
multi leg strategy like butterflies and condors.
Example to get the option
symbol.
shortLegOne.getOptionSymbol()
|
|
Util
|
This
is a utility class containing commonly used methods.
|
|
Math
|
Utility
class containing mathematical functions.
Example to get the square
root.
Math.sqrt(4)
|
|
TA
|
Technical
Analysis class containing TA specific functions.
Example
to
check for existence of Bullish DOJI Pattern in last 20 days
TA.hasPattern(CandleStickPattern.DOJI,
Bias.BULLISH,20);
|
Filters using APPL script
Advanced filters could be made using APPL scripts. The
APPL expression used for building the filter must evaluate to a Boolean value.
To add a new APPL filter click on the “Add APPL Filter” button from the
custom screener. See the figure below.
Figure below shows an example APPL filter which returns
strategies with Annual Return > 10
After entering the script click the validate button to
check for any error. After validation click save to add the filter to your screener.
Examples
1. Filter
to retrieve strategy data which has its stock with last traded price between 10
and 50.
{
stock.getLast()
> 10 && stock. getLast() < 50;
}
2. Filter to retrieve a stock which has an occurrence of Candle stick
pattern “Two Crows” in last 20 days.
{
TA.hasPattern(CandleStickPattern.TWO_CROWS,Bias.BEARISH,20);
}
3. Filter to find a Delta Neutral position for calendar spread.
{
shortDelta
= shortLegOne.getDelta();
longDelta
= longLegOne.getDelta();
netDelta
= longDelta - shortDelta;
netDelta
< 0.02;
}
Display Column using APPL script
Display columns could be added to the screener results
easily by creating an APPL script. Click on the “Add APPL Column” to
create a new display column. See the figure below.
After entering the script click the “validate and
preview” button to check for any errors and preview results. After
validation click “save” to add the display column to your screener.
Unlike the filters the script for the display column does not have to evaluate
to boolean.
Figure below shows the APPL script for display column
which shows a simple annualized return.
Examples
1. APPL
Script to create a display column to create a simple annualized rate of return
for a covered call strategy.
{
maxRetPcntage
= strategy.getMaxReturnPercentage();
returnPeriod
= shortLegOne.getOptionExpiryInDays();
annualReturn
= (maxRetPcntage/returnPeriod)*365;
Math.convertToTwoDigitPrecision(annualReturn);
}
2. APPL
Script to create a display column showing Net Delta for calendar spread.
{
shortDelta
= shortLegOne.getDelta();
longDelta
= longLegOne.getDelta();
netDelta
= longDelta - shortDelta;
Math.convertToTwoDigitPrecision(netDelta);
}

APL Language Elements
|
Item
|
Description
|
|
Comments
|
Also specified using //, e.g.
//
This is a comment
Multiple lines comments are specified using /*...*/, e.g.
/*
This is a
multi-line comment */
|
|
Identifiers / variables
|
Must start with a-z, A-Z. Can
then be followed by 0-9, a-z, A-Z, _ or $. e.g.
- Valid: var1,a99
- Invalid: 9v,!a99,1$
Variable names are case-sensitive,
e.g. var1 and Var1 are different variables.
N.B. the
following keywords are reserved, and cannot be used as a variable name or
property when using the dot operator:
or, and, eq, ne, lt, gt, le,
ge, div, mod, not, null, true, false, new.
|
|
Scripts
|
A script in APL is made up of zero or more statements.
|
|
Statements
|
A statement can be the empty statement, the semicolon (;) ,
block, assignment or an expression. Statements are optionally terminated with
a semicolon.
|
|
Block
|
A block is simply multiple statements inside curly braces ({, }).
|
|
Assignment
|
Assigns the value of a variable (var =
'a value')
|
|
Method calls
|
Calls a method of an object, e.g.
Math.sqrt(4)
will call the sqrt method from Math
object.
|
Literals
|
Item
|
Description
|
|
Integer Literals
|
1 or more digits from 0 to 9
|
|
Floating point Literals
|
1 or more digits from 0 to 9,
followed by a decimal point and then one or more digits from 0 to 9.
|
|
String literals
|
Can start and end with "
delimiters, e.g.
"Hello
world"
The
escape character is \; it only escapes the string delimiter
|
|
Boolean literals
|
The literals true and false can
be used, e.g.
val1
== true
|
|
Null literal
|
The null value is represented as in java using the literal null, e.g.
val1 == null
|
|
Array literal
|
A [ followed by one or more expressions separated by , and
ending with ], e.g.
[ 1,
2, "three" ]
This syntax creates an Object[].
APPL will attempt to strongly
type the array; if all entries are of the same class or if all entries are
Number instance, the array literal will be an MyClass[] in
the former case, a Number[] in the latter case.
Furthermore, if all entries
in the array literal are of the same class and that class has an equivalent
primitive type, the array returned will be a primitive array. e.g. [1, 2,
3] will be interpreted as int[].

Operator
|
Description
|
|
Boolean and
|
The usual && operator can be used, e.g.
cond1
&& cond2
|
|
Boolean or
|
The usual || operator can be used
cond1
|| cond2
|
|
Boolean not
|
The usual ! operator can be used e.g.
!cond1
|
|
Bitwise and
|
The usual & operator is used, e.g.
33
& 4
, 0010 0001 & 0000 0100 = 0.
|
|
Bitwise or
|
The usual | operator is used, e.g.
33 | 4
, 0010 0001 | 0000 0100 = 0010 0101 = 37.
|
|
Bitwise xor
|
The usual ^ operator is used, e.g.
33 ^ 4
, 0010 0001 ^ 0000 0100 = 0010 0100 = 37.
|
|
Bitwise complement
|
The usual ~ operator is used, e.g.
~33
, ~0010 0001 = 1101 1110 = -34.
|
|
Ternary conditional ?:
|
The usual ternary conditional operator condition
? if_true : if_false operator can be used ,e.g.
val1 ?
val1 : val2
|
|
Equality
|
The usual == operator can be used. For example
val1
== val2
1. null is
only ever equal to null, that is if you compare null to any non-null value,
the result is false.
2. Equality
uses the java equals method
|
|
Inequality
|
The usual != operator can be. For example
val1
!= val2.
|
|
Less Than
|
The usual < operator can be used .For example
val1
< val2
|
|
Less Than Or Equal To
|
The usual <= operator can be used. For example
val1
<= val2
|
|
Greater Than
|
The usual > operator can be used as well as the abbreviation gt. For
example
val1
> val2
|
|
Greater Than Or Equal To
|
The usual >= operator can be used. For example
val1
>= val2
|
|
Addition
|
The usual + operator is used. For example
val1 +
val2
|
|
Subtraction
|
The usual - operator is used. For example
val1 -
val2
|
|
Multiplication
|
The usual * operator is used. For example
val1 *
val2
|
|
Division
|
The usual / operator is used. For example
val1 /
val2
|
|
Modulus (or remainder)
|
The % operator is used
5 % 2
|
|
Negation
|
The unary - operator is used. For example
-12
|
|
Array access
|
Array elements may be accessed using square brackets e.g.
arr1[0]
|
Conditionals
|
Operator
|
