4 2. 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: The connection is performed by clean socket connection. For real trading SSL connection will be used. 3. 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 <string, j-value>); 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,

5 4. 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 for 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 5

6 5. 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: REAL: main port: 5112, streaming port: 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 is forced to close with no notification. Each command invocation should not contain more than 1kB of data user should send requests in 200 ms interval. However, this rule can be broken, but after 6th exceeding 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. 6

7 2. DEFAULT LOGIN CREDENTIALS Default login credentials can be obtained at: 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 Boolean 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 Boolean JSON value or, in case of error massage: status : false, errorcode : E123, errordescr : Error description Boolean 5. TIME FORMAT 7

8 Time is number of milliseconds from , 00:00 GMT. 6. FLOATING NUMBER FORMAT In all s '.' (period) is used as a decimal separator. 6. 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 drop the connection. command : login, arguments : userid : 100, password : PASSWORD, appid : test, appname : test Number (optional), application id, given by the xstore Support (optional), application name After successful login the system responds with the status message that can contain the streaming session id field: status : true, Boolean streamsessionid : , 8

9 Alternatively, when redirect is needed, the system responds with: status : false, redirect : REDIRECT_RECORD Boolean (optional) Format of REDIRECT_RECORD: mainport : 1234, streamingport : 1235, address : xapia.x-station.eu Number, main port for communication Number, streaming port, address that the user should reconnect to in order to login 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 command : logout No returndata field in output. Only status message is sent. 3.

26 REJECTED = 4 PRICED = 5 The transaction has been rejected. Prices received, used in EXE_REQUEST mode Field order should be filled with order number always when new trade order was opened successfully. 7. AVAILABLE STREAMING COMMANDS Streaming commands are performed on streaming connection on port of the server. Each streaming command takes as an argument streamsessionid which is sent in response message for login command performed in main connection. streamsessionid token allows to identify user in streaming connection. In one streaming connection multiple commands with different streamsessionid can be invoked. It will cause sending streaming data for multiple login sessions in one streaming connection. streamsessionid is valid until logout command is performed on main connection or main connection is disconnected. Command: gettickprices Description: The gettickprices command establishes subscription for quotations and allows to obtain the relevant information in real-time, as soon as it is available in the system. Moreover, gettickprices command response send profit information for all opened orders with given symbol number. Format of input to subscribe: command : gettickprices, symbol : EURUSD, streamsessionid : Format of input to unsubscribe: command : stoptickprices, symbol : EURUSD, The streamsessionid should contain the string value that was obtained from the system after successful login (see the description of the login command). The gettickprices command can be invoked many times for the same symbol, but only one subscription for a given symbol will be created. This command has no confirmation. After the subscription is established, the system sends data packets of the STREAMING_TICK_RECORD format. Format of tick prices in stream: 26

27 command : tickprices, data : STREAMING_TICK_RECORD STREAMING_TICK_RECORD: ask : , bid : , askvolume : 15000, bidvolume : 16000, high : , low : , symbol : KOMB.CZ, timestamp : , level : 0, quoteid : 0, Number, null if not applicable Number, null if not applicable Time Number, price level Number, source of price: 1 fixed 2 float 3 depth 4 - cross Command: gettrades Description: The gettrades command 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. Format of input to subscribe: command : gettrades, streamsessionid : Format of input to unsubscribe: command : stoptrades The streamsessionid should contain the string value that was obtained from the system after successful login (see the description of the login command). 27

28 The gettrades command can be invoked many times, but only one subscription for the trade data will be created. This command has no confirmation. After the subscription is established, the system sends data packets of the STREAMING_TRADE_RECORD format. Format of trade in stream: command : trade, data : STREAMING_TRADE_RECORD STREAMING_TRADE_RECORD: close_price : , close_time : null, closed : false, cmd : 0, comment : Web Trader, commission : 0.0, digits : 4, expiration : null, margin_rate : , open_price : 1.4, open_time : , order : , order2 : , position : , sl : 0.0, storage : -4.46, symbol : EURUSD, timestamp : , tp : 0.0, type : 0.0, volume : 0.10 Time or null if order is not closed Boolean Number, operation code Number, price precision Time or null if not applicable Time Number, order number for opened transaction Number, transaction id Number, position number (if type is 0 and 2) or transaction parameter (if type is 1), zero if stop loss is not set Time, zero if take profit is not set Number, 0 order opened, 1 order pending, 2 order closed New STREAMING_TRADE_RECORD are sent by streaming socket only in several cases: - Opening the trade 28

29 - 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 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. Command: getbalance Description: The getbalance command allows to get actual balance value for an account in real-time, as soon as it is available in the system. Format of input to subscribe: command : getbalance, streamsessionid : Format of input to unsubscribe: command : stopbalance, Format of balance in stream: command : balance, data : STREAMING_BALANCE_RECORD Format of STREAMING_BALANCE_RECORD: balance : , margin : 75.00, sum of balance and credit, margin 29

30 equity : requirements, sum of balance and all profits Command: getreqstatus Description: The getreqstatus command allows to get status for sent requests in real-time, as soon as it is available in the system. Format of input to subscribe: command : getreqstatus, streamsessionid : Format of input to unsubscribe: command : stopreqstatus, Format of balance in stream: command : reqstatus, data : STREAMING_REQ_STATUS_RECORD Format of STREAMING_REQ_STATUS_RECORD: requestid : 123, requeststatus : 23, Number, unique request id, can be negative Request status codes: ERROR=0 PENDING=1 REQUOTED=2 Price was requoted by dealer, used in EXE_INSTANT mode ACCEPTED=3 The transaction has been executed successfully 30
