Overview

Welcome to the FTX US API documentation. We offer complete REST, Websocket, and FIX APIs to suit your algorithmic trading needs.

REST API

HTTP-based API with full trading and asset management functionality, with public orderbook and trades data as well as private account data and order management.

REST endpoint URL: https://ftx.us/api

Requests and responses use JSON.

Authentication

import time
import hmac
from requests import Request

ts = int(time.time() * 1000)
request = Request('GET', '<api_endpoint>')
prepared = request.prepare()
signature_payload = f'{ts}{prepared.method}{prepared.path_url}'.encode()
signature = hmac.new('YOUR_API_SECRET'.encode(), signature_payload, 'sha256').hexdigest()

request.headers[f'FTXUS-KEY'] = 'YOUR_API_KEY'
request.headers[f'FTXUS-SIGN'] = signature
request.headers[f'FTXUS-TS'] = str(ts)

# Only include line if you want to access a subaccount. Remember to URI-encode the subaccount name if it contains special characters!
# request.headers[f'FTXUS-SUBACCOUNT'] = 'my_subaccount_nickname'

var method = HttpMethod.Get
var endpoint = $"/api/account";
var request = new HttpRequestMessage(method, endpoint);
var _nonce = (DateTime.UtcNow - start).TotalMilliseconds;

var hashMaker = new HMACSHA256(Encoding.UTF8.GetBytes(""YOUR_API_SECRET""));
var signaturePayload = $"{_nonce}{method.ToString().ToUpper()}{endpoint}";
var hash = hashMaker.ComputeHash(Encoding.UTF8.GetBytes(signaturePayload));
var hashString = BitConverter.ToString(hash).Replace("-", string.Empty);
var signature = hashString.ToLower();

request.Headers.Add("FTXUS-KEY", "YOUR_API_KEY");
request.Headers.Add("FTXUS-SIGN", signature);
request.Headers.Add("FTXUS-TS", _nonce.ToString());

For authenticated requests, the following headers should be sent with the request:

Rate limits

Please do not send more than 30 requests per second: doing so will result in HTTP 429 errors. We strongly recommend using the websocket API for faster market and account data.

Websocket API

Streaming API with the most up-to-date market and account order data. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply.

Websocket endpoint URL: wss://ftx.us/ws/

Requests and responses use JSON.

You can find sample code here: https://github.com/ftexchange/ftx

Request process

Websocket connections go through the following lifecycle:

Request format

Messages sent to the server should contain the following dictionary items:

Response format

Public Channels

Ticker

The ticker channel provides the latest best bid and offer market data. All messages are updates (update), and the data field contains: - bid: Best bid price if a bid exists, else null - ask: Best ask price if an ask exists, else null - last: Last trade price if it exists, else null - time: Timestamp

Markets

The markets channel provides information on the full set of tradable markets and their specifications. After subscription and once per minute, you will receive a partial message with information on all markets. If there are updates to markets (listings, delistings, or changes to specs), you will be notified through update messages. The data field both types of messages will contain a list of market information dictionaries, each of which contains:

Trades

The trades channel provides data on all trades in the market. All messages are updates of new trades (update) and the data field contains: - price: Price of the trade - size: Size of the trade - side: Side of the taker in the trade - liquidation: true if the trade involved a liquidation order, else false - time: Timestamp

Orderbooks

The orderbook channel provides data about the orderbook's best 100 orders on either side.

Initial snapshot

Upon subscribing, you will receive one snapshot of the orderbook (partial) with a data field containing:

The bids and asks are formatted like so: [[best price, size at price], [next next best price, size at price], ...]

Updates

After receiving your snapshot, you will be streamed updates (message type is update) that have data fields with:

The bids and asks fields contain updates to the orderbook.

Checksum

Every message contains a signed 32-bit integer checksum of the orderbook. You can run the same checksum on your client orderbook state and compare it to checksum field. If they are the same, your client's state is correct. If not, you have likely lost or mishandled a packet and should re-subscribe to receive the initial snapshot.

The checksum operates on a string that represents the first 100 orders on the orderbook on either side. The format of the string is:

For example, if the orderbook was comprised of the following two bids and asks:

The string would be '5005.5:10:5001.0:6:4995.0:5:5002.0:7'

If there are more orders on one side of the book than the other, then simply omit the information about orders that don't exist.

For example, if the orderbook had the following bids and asks:

The string would be '5005.5:10:5001.0:6:4995.0:5'

The final checksum is the crc32 value of this string.

Private Channels

Authentication

You can log in by sending a message like so %{code}

{
  "args": {
    "key": "<api_key>",
    "sign": "<signature>",
    "time": "<ts>"
  },
  "op": "login"
}

As an example, if:

sign would be d10b5a67a1a941ae9463a60b285ae845cdeac1b11edc7da9977bef0228b96de9

One websocket connection may be logged in to at most one user. If the connection is already authenticated, further attempts to log in will result in 400s.

Fills

You will receive messages so:

{
  "channel": "fills",
  "data": {
    "fee": 78.05799225,
    "feeRate": 0.0014,
    "id": 7828307,
    "liquidity": "taker",

    "type": "order"
  },
  "type": "update"
}

This channel streams your fills across all markets. You can subscribe to it on an authenticated connection by sending {'op': 'subscribe', 'channel': 'fills'}.

Orders

You will receive messages so:

{
  "channel": "orders",
  "data": {
    "id": 24852229,
    "clientId": null,
    "market": "BTC/USD",
    "type": "limit",

    "filledSize": 0.0,
    "remainingSize": 0.0,
    "avgFillPrice": 0.2978
  },
  "type": "update"
}

This channel streams updates to your orders across all markets. You can subscribe to it on an authenticated connection by sending {'op': 'subscribe', 'channel': 'orders'}.

FIX API

FIX (Financial Information eXchange) is a standard electronic messaging protocol which can be used to place orders, receive order updates and executions, and cancel orders. Our FIX api is based on the FIX 4.2 specification and modeled after FIX implementations of other popular cryptocurrency exchanges.

You can find sample client code here: https://github.com/ftexchange/ftx

FIX endpoint URL: tcp+ssl://fix.ftx.us:4363

Clients should connect to the endpoint using SSL.

Sequence numbers are reset for each connection. Resend request and sequence reset messages are not supported.

Messages

8=FIX.4.2|9=162|35=A|49=zyfvB4QPg0A3kkVgqUE9V1fOA-Y6jhdG3seqIIZx|56=FTXUS

All messages should include the following header:

This documentation uses | to represent the FIX field separator (byte 0x01). It should be replaced by 0x01 in actual messages.

Tag Name Example Description
8 BeginString FIX.4.2 Must be set to "FIX.4.2"
9 BodyLength 162 Length of the message body in bytes
35 MsgType 8 Message type
49 SenderCompID zyfvB4QPg0A3kkVgqUE9V1fOA-Y6jhdG3seqIIZx Client API key (for messages from the client)
56 TargetCompID FTXUS Must be set to "FTXUS" (for messages from the client) 
34=1|52=20190525-07:17:48

Messages should also include a sequence number MsgSeqNum (34) and a timestamp SendingTime (52). Sequence numbers start at 1 and must be incremented with every message. Messages with duplicate or out-of-order sequence numbers will be rejected. Sequence numbers are reset on new connections.

Logon (A)

Sent by the client to initiate a FIX session. Must be the first message sent after a connection is established. Only one session can be established per connection; additional Logon messages are rejected.

Request

8=FIX.4.2|9=162|35=A|49=zyfvB4QPg0A3kkVgqUE9V1fOA-Y6jhdG3seqIIZx|56=FTXUS|34=1|52=20190525-07:51:51|98=0|108=30|96=8f7e7d37f8033ad249c1833687c230b6f4663f0dd72752899776bab9aa064783|10=237|
Tag Name Example Description
35 MsgType A
98 EncryptMethod 0 Must be set to "0" (None)
108 HeartBInt 30 Must be set to "30"
96 RawData 8f7e...4783 Signature (see below)
8013 CancelOrdersOnDisconnect Y "Y": all account orders will be cancelled at the end of the session. "S": all orders placed during the session will be cancelled at the end of the session. Default: no orders will be cancelled.
1 Account "my_subaccount" Optional subaccount name; can be omitted if authenticating for main account

Signature

from datetime import datetime
import hmac

api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'

sending_time = datetime.now().strftime('%Y%m%d-%H:%M:%S')

sign_target = '\x01'.join([
    sending_time,  # SendingTime
    'A',  # MsgType
    '1',  # MsgSeqNum
    api_key,  # SenderCompID
    'FTXUS',  # TargetCompID
])

signature = hmac.new(api_secret.encode(), sign_target.encode(), 'sha256').hexdigest()


let crypto = require('crypto');

let apiKey = 'YOUR_API_KEY';
let apiSecret = 'YOUR_API_SECRET';

let sendingTime = '20190525-07:51:51';

let signTarget = [
    sendingTime,  // SendingTime
    'A',  // MsgType
    '1',  // MsgSeqNum
    apiKey,  // SenderCompID
    'FTXUS',  // TargetCompID
].join('\x01');

let hmac = crypto.createHmac('sha256', apiSecret);
let signature = hmac.update(signTarget).digest('hex');

For security, the Logon message must be signed by the client. To compute the signature, concatenate the following fields, joined by the FIX field separator (byte 0x01), and compute the SHA256 HMAC using the API secret:

The resulting hash should be hex-encoded.
