Documentation

CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage.

73% of retail investor accounts lose money when trading CFDs with this provider.

You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

RestAPI

Our REST API is a web-based API using a Websocket connection and was developed with algorithmic trading in mind.

Developers and investors can create custom trading applications, integrate into our platform, back test strategies and build robot trading. Calls can be made in any language that supports a standard HTTP.

We utilize the new OAuth 2.0 specification for authentication via token. This allows for a more secure authorization to access your application and can easily be integrated with web applications, mobile devices, and desktop platforms

With the use of the socket.io library, the API has streaming capability and will push data notifications in a JSON format. Your application will have access to our real-time streaming market data, subscribe in real time access to trading tables and place live trades. You can also retrieve market data price history. You can find instructions on documentation and sample code.

Header Description Values Req’d
HTTP version Version of HTTP used HTTP/1.1 Y
User-Agent Identification of the client software xxxxxx_software Y
Accept Acceptable response MIME type application/json Y
Content-Type Media type of the request application/x-www-form-urlencoded Y
Authorization Authorization string containing “Bearer “, ID of socket.io connection and persistent token 'Bearer ' + socket_id + api_token Y
  Sample Request
  GET /socket.io/?access_token=cj5wedhq3007v61fe935ihqed&EIO=3&transport=polling&t=Lsd_lZY&b64=1 
  HTTP/1.1 
  User-Agent: node-XMLHttpRequest 
  Accept: */* 
  Host: api.fxcm.com 
  Connection: close

What 't' means

"t" is the table id:

t table ID
1 Open Position
2 Closed Position
3 Order
5 Summary
6 Account

Subscribe vs snapshot:

FXCM Rest API provides two ways to deliever data. susbcribe vs snapshot.

After susbcribe, data will be pushed to your socket whenever there is an update. You can susbcribe Market data stream /susbcribe or live table update /trading/susbcribe. You can also unsubscribe. You can request a snapshot of trading tables via /trading/get_model.

  Model choices: 'Offer', 'OpenPosition', 'ClosedPosition', 'Order', 'Summary', 'LeverageProfile', 'Account', 'Properties'.   

How to place market order:

This function is very similar to our market order in TSweb2.0. Since it is a market order, order will be filled at market by system. Client don’t need to specify the price, you can set rate=0. Order_type=AtMarket tells the server it is a market order, not MarketRange order. Stop and limit are the price you need to specify when you want to exit the market in stoploss/take profit price. Is_in_pips=true means stop/limit is in pips, otherwise it is in real value. Stop should be negative value.

  Placing Market order:
  POST /trading/open_trade
  account_id=1537581&symbol=EUR%2FUSD&is_buy=false&rate=0&amount=5&order_type=AtMarket&time_in_force=GTC

OrderID vs TradeID:

OrderID and TradeID are different. In Market order, an order id is created straightaway and it is in callback immediately.

  {"response":{"executed":true},"data":{"type":0,"orderId":81712802}}

A trade id is not generated until after order is executed. You have to subscribe the order table and listing the live update and look up the trade id. You will not get trade id in snapshot, because that information was gone when you submit the request. to link the orderID to TradeID, you need to subscribe order table. Open position table, you will get order id immediately from response. You will see insert in order table, follow by update and delete on order table. In Open position, at the same time you will see same order ID + trade ID been insert in open position table then followed by update. Now you know what order combined to what trade ID

  Examples:
  Subscribing for Orders table:
  POST /trading/subscribe
  models=Order
  
  Placing Market order:
  POST /trading/open_trade
  account_id=1537581&symbol=EUR%2FUSD&is_buy=false&rate=0&amount=5&order_type=AtMarket&time_in_force=GTC

  Response from server:
  {"executed":true}{"type":0,"orderId":390285837}

  Received Order record from /trading/subscribe with order_id and trade_id:
  {"t":3,"ratePrecision":5,"orderId":"390285837","tradeId":"170162801","time":"04252018120716391","accountName":"01537581","accountId":"1537581","timeInForce":"GTC","expireDate":"","currency":"EUR/USD","isBuy":false,"buy":0,"sell":1.21818,"type":"OM","status":2,"amountK":5,"currencyPoint":0.5,"stopMove":0,"stop":0,"stopRate":0,"limit":0,"limitRate":0,"isEntryOrder":false,"ocoBulkId":0,"isNetQuantity":false,"isLimitOrder":false,"isStopOrder":false,"isELSOrder":false,"stopPegBaseType":-1,"limitPegBaseType":-1,"range":0,"action":"I"}

Furthermore, a single market order can have many TradeIDs, if they are partial fills or closing of other orders. in this case, its more approriate to provide the OrderID which ties back to that spcific market order request, from there you can join this OrderID to any associated.

In entry order, an order ID is in callback function. You can also see it on order table sanpshot. but you will not get TradeID until order been executed.

How to place trailing stop

The fixed trailing stop should be 10 or above, for dynamic trailing stop = 1, number between 2-9 will be rejected. also the parameter is trailing_stop_step

  Example Entry order with trailing stop of 10 pips:
  POST /trading/create_entry_order account_id=1537581&symbol=EUR%2FUSD&is_buy=true&rate=1.1655&amount=3&order_type=Entry&time_in_force=GTC&stop=-50&trailing_stop_step=10&is_in_pips=true

Difference between account name and account ID

There is a difference bewteen account name and account id. usually removing the heading zeros are account ID. and you need to pass account_id when you place orders. You can retrieve this information from /trading/get_model/Accounts.

  Wrong:
  {"is_buy":false,"account_id":"00654061","symbol":"EUR/USD","rate":1.15,"amount":11,"stop":-40,"is_in_pips":true,"order_type":"AtMarket","time_in_force":"GTC"}

  ERR noExec: /trading/create_entry_order
  {"code":3,"message":"Amount should be divisible by 10","parameters":["10"]}

  Correct:
  {"is_buy":false,"account_id":"654061","symbol":"EUR/USD","rate":1.15,"amount":11,"stop":-40,"is_in_pips":true,"order_type":"AtMarket","time_in_force":"GTC"}
  
  request # 2  has been executed: {
  "response": {"executed": true}, "data": {"type": 0,"orderId": 194963057}}
