Strategy Options Configuration

You can add some extra arguments for the strategy and change these arguments for every live trade, backtest or simulation. For example, if you have the following configuration for a strategy

Warning

All arguments are actually stored and parsed as String type in your strategy code. So you have to parse it by your self!

Type

• Boolean

  A STRING that indicates either true or false

• Number

  A STRING that represents a float value.

• String

  A STRING that holds a ASCII string

• Select

  A STRING that holds a list of ASCII string. Separated by the symbol vertical bar |.

Example

Suppose you use the following configuration

Variable	Description	Type	Default Value
MyArgA	true/false	Boolean	true
MyArgB	a float num	Number	10.9
MyArgC	a ASCII Str	String	Hello World!
MyArgD	a ASCII list	Select	OptionA|OptionB|OptionC

Note: Only ASCII string is supported currently.

Then you're allowed to tweak these variables to be used in your strategy before trading. MyArgD will appear as a list consisting of OptionA, OptionB and OptionC.

JavaScript Example

You can access these arguments by this.argName or this['argName'].

Log(this['MyArgA']);        // true
Log(typeof this['MyArgA']); // string

Log(this['MyArgB']);        // 10.9
Log(typeof this['MyArgB']); // string

Log(this['MyArgC']);        // Hello World!
Log(typeof this['MyArgC']); // string

Log(this['MyArgD']);        // OptionC
Log(typeof this['MyArgD']); // string

All of the types are string in javascript

So if you want to check MyArgA is true or not, you have to use it like if(this['MyArgA'] === 'true') {...} instead of if(this['MyArgA]) { ... }.

Python Example

You can access these arguments by self['argName'].

Log(self['MyArgA']) # true
Log(str(self['MyArgA'].__class__)) # <class 'str'>

Log(self['MyArgB']) # 10.9
Log(str(self['MyArgB'].__class__)) # <class 'str'>

Log(self['MyArgC']) # Hello World!
Log(str(self['MyArgC'].__class__)) # <class 'str'>

Log(self['MyArgD']) # OptionC
Log(str(self['MyArgD'].__class__)) # <class 'str'>

All of the types are string in python

So if you want to check MyArgA is true or not, you have to use it like if self['MyArgA'] == 'true' instead of if self['MyArgA].
