How to use

Prerequisites

To Enable database logging support you must have an active migrated database by following the database setup guide

Syntax Highlighting

To enable syntax highlighting for vscode download extension graphman65/vscode-tengo then add ".gct" to vscode-tengo package.json settings to enable highlighting of our files.

Configuration

The gctscript configuration struct is currently:

type Config struct {
	Enabled       bool          `json:"enabled"`
	ScriptTimeout time.Duration `json:"timeout"`
	AllowImports  bool          `json:"allow_imports"`
	AutoLoad      []string      `json:"auto_load"`
	Verbose       bool          `json:"Verbose"`
}

With an example configuration being:

 "gctscript": {
  "enabled": true,
  "timeout": 600000000,
  "allow_imports": true,
  "auto_load": [],
  "debug": false
 },

Script Control

• You can autoload scripts on bot start up by placing their name in the "auto_load" config entry

  "auto_load": ["one","two"]

  This will look in your GoCryptoTrader data directory in a folder called "scripts" for files one.gct and two.gct and autoload them

• Manual control of scripts can be done via the gctcli command with support for the following:

  • Enable/Disable GCTScript:

   gctcli enablesubsystem "gctscript"
   gctcli disablesubsystem "gctscript"

  • Start/Execute:

    gctcli script execute <scriptname> <pathoverride>
    gctcli script execute "timer.gct" "~/gctscript"
  
    {
      "status": "ok",
      "data": "timer.gct executed"
    }

  • Stop:

    gctcli script stop <uuid>
    gctcli script stop 821bd73e-02b1-4974-9463-874cb49f130d
  
    {
      "status": "ok",
      "data": "821bd73e-02b1-4974-9463-874cb49f130d terminated"
    }

  • Status:

    gctcli script status 
  
    {
      "status": "ok",
      "scripts": [
        {
          "uuid": "821bd73e-02b1-4974-9463-874cb49f130d",
          "name": "timer.gct",
          "next_run": "2019-11-14 13:11:40.224919456 +1100 AEDT m=+91.062103259"
        }
      ]
    }

  • Read file:

    gctcli script read <filename>
    gctcli script read "timer.gct"
  
    {
      "status": "ok",
      "script": {
      "name": "timer.gct",
      "path": "/home/x/.gocryptotrader/scripts"
      },
      "data": "fmt := import(\"fmt\")\nt := import(\"times\")\n\nname := \"run\"\ntimer := \"5s\"\n\nload := func() {\n\tfmt.printf(\"5s %s\\n\",t.now())\n}\n\nload()\n"
    }

  • Query running script:

    gctcli script query <uuid>
    gctcli script query 821bd73e-02b1-4974-9463-874cb49f130d
    {
      "status": "ok",
      "script": {
      "UUID": "bf692e2d-fa1e-4d95-92fd-33d7634d3d77",
      "name": "timer.gct",
      "path": "/home/x/.gocryptotrader/scripts",
      "next_run": "2019-12-12 07:44:19.747572406 +1100 AEDT m=+16.782773385"
    },
    "data": "fmt := import(\"fmt\")\nt := import(\"times\")\n\nname := \"run\"\ntimer := \"5s\"\n\nload := func() {\n\tfmt.printf(\"5s %s\\n\",t.now())\n}\n\nload()\n"
    }
    load()  

  • Add script to autoload:

  gctcli script autoload add timer
  {
    "status": "success",
    "data": "script timer added to autoload list"
  }

  • Remove script from autoload:

    gctcli script autoload remove timer
    {
      "status": "success",
      "data": "script timer removed from autoload list"
    }

Scripting & Extending modules

The scripting engine utilises tengo an intro tutorial for it can be found here

Modules have been written so far linking up common exchange features including

• Orderbook
• Ticker
• Order Management
• Account information
• Withdraw funds
• Get Deposit Addresses

Extending or creating new modules:

Extending an existing module the exchange module for example is simple

• Open required module
• Add to exchangeModule map
• Define function with signature (args ...objects.Object) (ret objects.Object, err error)

Similar steps can be taken to add a new module with a few adjustments

• Open required GCT
• Add module name to GCTModules map

GCT module methods

Current supported methods added and exposed to scripts are as follows:

accountinfo
-> exchange:string

depositaddress
-> exchange:string
-> currency:string

orderbook
-> exchange:string
-> currency pair:string
-> delimiter:string
-> asset:string

ticker
-> exchange:string
-> currency pair:string
-> delimiter:string
-> asset:string

pairs
-> exchange:string
-> enabled only:bool
-> asset:string

queryorder
-> exchange:string
-> order id:string

submitorder
-> exchange:string
-> currency pair:string
-> delimiter:string
-> order type:string
-> order side:string
-> price:float64
-> amount:float64
-> client_id:string

withdrawfiat
-> exchange:string
-> currency:string
-> description:string
-> amount:float64
-> bank id:string

withdrawcrypto
-> exchange:string
-> currency:string
-> address:string
-> address tag:string
-> amount:float64
-> fee:float64
-> description:string
