Protocol Documentation

Version 2.2

  1. Introduction

    This document presents information on xStation API communication protocol. The communication protocol of the xStation API uses JSON format.

    JSON format used by the server doesn't allow extensions (e.g. comments, other flags). JSON format standardization document is available under the following link: http://tools.ietf.org/html/rfc4627.

    The connection is performed by clean socket connection. For real trading SSL connection will be used.

  2. Definitions

    The following definitions will be used in this specification document:

    • simple type: type, which value is itself: int, int64, string, double, bool;
    • j-value (JSON value): any simple type, j-object or j-array;
    • j-object (JSON object): a record containing any number of named j-values (pair );
    • j-array (JSON array): an array where each element is j-value;
    • j-subvalue: j-value which is a component of a j-object.

    A j-object can contain zero elements. A j-array can have zero length. The name of j-value can be an empty string.

    Encoding of strings is set to UTF-8. In this format the server sends and receives data.

    Definition of unix-time:

    Unix time, or POSIX time, is a system for describing points in time, defined as the number of milliseconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970.
  3. General data format

    Each packet consists of exactly one main, unnamed j-value. The data stream consists of consecutive j–values, with no punctuation.

    The main j-value is a j-object containing exactly two j-subvalues which are j-objects. The first j-subobject is named header and consists of at least a field type as a simple type string. This is a packet type. The second j-subobject of the main packet j-object is named data and its content is specific to a given packet type. The specifications for different types of packages are described in the next chapter.

    A sample of properly defined packet:

    {
    	"command" : "login",
    	"arguments" : {
    		"userId" : 1000,
    		"password": "PASSWORD"
    	}
    }
  4. Communication with the xStation API

    There are two IPs, that can be used interchangeably:

    • xapia.x-station.eu
    • xapib.x-station.eu

    Here are the addresses of DEMO and REAL servers:

    • DEMO: main port: 5124, streaming port: 5125,
    • REAL: main port: 5112, streaming port: 5113.

    Both servers use SSL connection.

    Communication is established as long as both server and client have opened and connected sockets

    For convenience server guarantees that every separate reply to client command returned by server will be separated by two new line characters ("\n").

    1. Connection validation

      In order to provide best service for all users xStation API set rules on connection and data send process. If any of the following rules is breached, then connection is closed immediately without server notification.

      List of rules:

      • Every new connection that fails to deliver data within one second from when it is established may be forced to close with no notification,
      • Each command invocation should not contain more than 1kB of data,
      • User should send requests in 200 ms intervals. This rule can be broken, but if it happens 6 times in a row the connection is dropped,
      • Each command should be proper JSON object.

      Exception:

      If the client sends a request that is a valid JSON object, but does not conform to the published API (incorrect command, missing fields, etc.), the response is sent back with the error description but the connection is not closed.

      This rule prevents incorrect messages from reaching further down the processing chain and allows clients to analyze and understand the source of problem.

    2. Default login credentials

      Default login credentials can be obtained at: http://developers.xstore.pro/panel/.

    3. Input data format

      The input data format is a JSON object that consists of service name and command name. Some commands also require an object of command's arguments.

      If optional prettyPrint field is set to true, an output JSON is printed in human-readable format. prettyPrint field can be omitted.

      {
      	"command": "commandName",
      	"arguments": {
      		"arg1Name": 10,
      		"arg2Name": "Some text",
      		...
      	},
      	"prettyPrint": true
      }
    4. Output data format

      The output data format is a JSON object that consists of status and returnData fields if command succeeded, or status, errorCode and errorDescr fields if an error occurred.

      {
      	"status": true,
      	"returnData": JSON value
      }

      or, in case of an error:

      {
      	"status": false,
      	"errorCode": "E123",
      	"errorDescr": "Error description"
      }
    5. Time format

      Time is number of milliseconds from 01.01.1970, 00:00 GMT.

    6. Floating number format

      In all Floating numbers '.' (period) is used as a decimal separator.

  5. Available commands

    Request-Reply commands are performed on main connection socket. The reply is sent by main connection socket.

    1. Login

      In order to perform any action client application have to perform login process. No functionality is available before proper login process.

      After initial login, a new session is created and all commands are executed for a logged user until he/she logs out or drops the connection.

      Request:

      Parameters:

      NameTypeDesc
      userIdNumberuserId
      passwordStringpassword
      appIdString(optional) application ID provided by the xStore Support Team
      appNameString(optional) application name

      Example:

      {
      	"command": "login",
      	"arguments": {
      		"userId": 100,
      		"password": "PASSWORD",
      		"appId": "test",
      		"appName": "test"
      	}
      }
      

      After successful login the system responds with the status message that can contain the String representing streamSessionId field:

      
      {
      	"status": true,
      	"streamSessionId": "8469308861804289383"
      }
      
      

      Alternatively, when redirect is needed, the system responds with:

      {
      	"status": false,
      	"redirect": REDIRECT_RECORD (optional)
      }
      
      

      Format of REDIRECT_RECORD:

      nametypedescription
      mainPortNumberMain port for communication
      streamingPortNumberstreaming port
      addressStringaddress that the user should reconnect to in order to login

      Example:

      {
      	"mainPort": 1234,
      	"streamingPort": 1235,
      	"address": "xapia.x-station.eu"
      }
      

      The status of the correct login process is true. If the status is false, REDIRECT_RECORD may be present which defines the server that the user should log into instead of the current one. It is assumed that when using REDIRECT_RECORD data, secure connection (SSL) should be used.

      The streamSessionId field of the string type, if present, is a token that can be used to establish a streaming subscription on a separate network connection. streamSessionId is used in streaming subscription commands.

      streamSessionId is unique for the given main session and will change between login sessions.

    2. Logout

      Format of input:

      {
      	"command": "logout"
      }
      

      No returnData field in output. Only status message is sent.

    5. Command: getTrades

      Description: Establishes subscription for user trade status data and allows to obtain the relevant information in real-time, as soon as it is available in the system.

      Subscribe format:

      Example:

      {
      	"command" : "getTrades",
      	"streamSessionId" : "8469308861804289383"
      }
      Unsubscribe format:

      Example:

      {
      	"command" : "stopTrades"
      }
      Format of data in stream:
      {
      	"command" : "trade",
      	"data" : STREAMING_TRADE_RECORD
      }

      Format of STREAMING_TRADE_RECORD:

      New STREAMING_TRADE_RECORD are sent by streaming socket only in several cases:

      • - Opening the trade
      • - Closing the trade
      • - Modification of trade parameters
      • - Explicit trade update done by server system to synchronize data.

      Situation that trade was closed can be checked by field closed set to true in STREAMING_TRADE_RECORD format. Also close_time field will NOT be set to null. Various reasons of trade close could be found out by information in comment field of STREAMING_TRADE_RECORD for closed order. If the comment remained unchanged from that of opened order, then the order was closed by user. If there is annotation in comment string like:

      • - "sl", then the trade was closed by stop loss
      • - "tp", then the trade was closed by take profit
      • - "so", then the trade was closed because of Stop Out (lack of money to maintain position)

      The annotation are in brackets (regular or square, depending on situation) with additional data about the closing action.
