FIX API

[!NOTE] This API can only be used with the SPOT Exchange.

General API Information

FIX connections require TLS encryption. Please either use native TCP+TLS connection or set up a local proxy such as stunnel to handle TLS encryption.
APIs have a timeout of 10 seconds when processing a request. If a response from the Matching Engine takes longer than this, the API responds with "Timeout waiting for response from backend server. Send status unknown; execution status unknown." (-1007 TIMEOUT)
- This does not always mean that the request failed in the Matching Engine.
- If the status of the request has not appeared in User Data Stream, please perform an API query for its status.

FIX sessions only support Ed25519 keys.
You can setup and configure your API key permissions on Spot Test Network.

FIX API Order Entry sessions

Endpoint is: tcp+tls://fix-oe.testnet.binance.vision:9000
Supports placing orders, canceling orders, and querying current limit usage.
Supports receiving all of the account's ExecutionReport<8> and List Status<N>.
Only API keys with FIX_API are allowed to connect.
QuickFIX Schema can be found here.

FIX API Drop Copy sessions

Endpoint is: tcp+tls://fix-dc.testnet.binance.vision:9000
Supports receiving all of the account's ExecutionReport<8> and List Status<N>.
Only API keys with FIX_API or FIX_API_READ_ONLY are allowed to connect.
QuickFIX Schema can be found here.

FIX Market Data sessions

Endpoint is: tcp+tls://fix-md.testnet.binance.vision:9000
Supports market data streams and active instruments queries.
Does not support placing or canceling orders.
Only API keys with FIX_API or FIX_API_READ_ONLY are allowed to connect.
QuickFIX Schema can be found here.

FIX Connection Lifecycle

All FIX API sessions will remain open for as long as possible, on a best-effort basis.
There is no minimum connection time guarantee; a server can enter maintenance at any time.
- When a server enters maintenance, a News <B> message will be sent to clients every 10 seconds for 10 minutes, prompting clients to reconnect. Upon receiving this message, a client is expected to establish a new session and close the old one. If the client does not close the old session within the time frame, the server will proceed to log it out and close the session.
After connecting, the client must send a Logon <A> request. For more information please refer to How to sign a Logon request.
The client should send a Logout <5> message to close the session before disconnecting. Failure to send the logout message will result in the session’s SenderCompID (49) being unusable for new session establishment for a duration of 2x the HeartInt (108) interval.
The system allows negotiation of the HeartInt (108) value during the logon process. Accepted values range between 5 and 60 seconds.
- If the server has not sent any messages within a HeartInt (108) interval, a HeartBeat <0> will be sent.
- If the server has not received any messages within a HeartInt (108) interval, a TestRequest <1> will be sent. If the server does not receive a HeartBeat <0> containing the expected TestReqID (112) from the client within HeartInt (108) seconds, the server will send a Logout <5> message and close the connection.
- If the client has not received any messages within a HeartInt (108) interval, the client is responsible for sending a TestRequest <1> to ensure the connection is healthy. Upon receiving such a TestRequest <1>, the server will respond with a Heartbeat <0> containing the expected TestReqID (112). If the client does not receive the server’s response within a HeartInt (108) interval, the client should close the session and connection and establish new ones.

API Key Permissions

To access the FIX API order entry sessions, your API key must be configured with the FIX_API permission.

To access the FIX Drop Copy sessions, your API key must be configured with either FIX_API_READ_ONLY or FIX_API permission.

To access the FIX Market Data sessions, your API key must be configured with either FIX_API or FIX_API_READ_ONLY permission.

FIX sessions only support Ed25519 keys.

On message processing order

The MessageHandling (25035) field required in the initial Logon<A> message controls whether the messages may get reordered before they are processed by the engine.

UNORDERED(1) messages from client are allowed to be sent to the engine out of order.
SEQUENTIAL(2) messages from client are always sent to the engine in the MsgSeqNum (34) order.

[!TIP] UNORDERED(1) should offer better performance when there are multiple messages in flight from the client to the server.

Response Mode

By default, all concurrent order entry sessions receive all of the account's successful ExecutionReport<8> and ListStatus<N> messages, including those in response to orders placed from other FIX sessions and via non-FIX APIs.

Use the ResponseMode (25036) field in the initial Logon<A> message to change this behavior.

EVERYTHING(1): The default mode.
ONLY_ACKS(2): Receive only ACK messages whether operation succeeded or failed. Disables ExecutionReport push.

Timing Security

All requests require a SendingTime(52) field which should be the current timestamp.
An additional optional field, RecvWindow(25000), specifies for how long the request stays valid in milliseconds.
If RecvWindow(25000) is not specified, it defaults to 5000 milliseconds only for the Logon<A> request. For other requests if unset, the RecvWindow check is not executed.
- Maximum RecvWindow(25000) is 60000 milliseconds.
Request processing logic is as follows:

serverTime = getCurrentTime()
if (SendingTime < (serverTime + 1 second) && (serverTime - SendingTime) <= RecvWindow) {
  // begin processing request
  serverTime = getCurrentTime()
  if (serverTime - SendingTime) <= RecvWindow {
    // forward request to Matching Engine
  } else {
    // reject request
  }
  // finish processing request
} else {
  // reject request
}

How to sign Logon `<A>` request

The Logon<A> message authenticates your connection to the FIX API. This must be the first message sent by the client.

The Username (553) field is required to contain the API key.
The RawData (96) field is required to contain a valid signature made with the API key.

The signature payload is a text string constructed by concatenating the values of the following fields in this exact order, separated by the SOH character:

MsgType (35)
SenderCompId (49)
TargetCompId (56)
MsgSeqNum (34)
SendingTime (52)

Sign the payload using your private key. Encode the signature with base64. The resulting text string is the value of the RawData (96) field.

Here is a sample Python code implementing the signature algorithm:

import base64

from cryptography.hazmat.primitives.asymmetric.ed25519 import Ed25519PrivateKey
from cryptography.hazmat.primitives.serialization import load_pem_private_key

def logon_raw_data(private_key: Ed25519PrivateKey,
                   sender_comp_id: str,
                   target_comp_id: str,
                   msg_seq_num: str,
                   sending_time: str):
    """
    Computes the value of RawData (96) field in Logon<A> message.
    """
    payload = chr(1).join([
        'A',
        sender_comp_id,
        target_comp_id,
        msg_seq_num,
        sending_time,
    ])
    signature = private_key.sign(payload.encode('ASCII'))
    return base64.b64encode(signature).decode('ASCII')


with open('private_key.pem', 'rb') as f:
    private_key = load_pem_private_key(data=f.read(),
                                       password=None)

raw_data = logon_raw_data(private_key,
                          sender_comp_id='5JQmUOsm',
                          target_comp_id='SPOT',
                          msg_seq_num='1',
                          sending_time='20240612-08:52:21.613')

The values presented below can be used to validate the correctness of the signature computation implementation:

Field	Value
MsgType (35)	`A`
SenderCompID (49)	`EXAMPLE`
TargetCompID (56)	`SPOT`
MsgSeqNum (34)	`1`
SendingTime (52)	`20240627-11:17:25.223`

Limits

Message Limits

Each connection has a limit on how many messages can be sent to the exchange.
The message limit does not count the messages sent in response to the client.
Breaching the message limit results in immediate Logout <5> and disconnection.
To understand current limits and usage, please send a LimitQuery<XLQ> message. A LimitResponse<XLR> message will be sent in response, containing information about Order Rate Limits and Message Limits.
FIX Order entry sessions have a limit of 10,000 messages every 10 seconds.
FIX Drop Copy sessions have a limit of 60 messages every 60 seconds.
FIX Market Data sessions have a limit of 2000 messages every 60 seconds.

Connection Limits

Each Account has a limit on how many TCP connections can be established at the same time.
The limit is reduced when the TCP connection is closed. If the reduction of connections is not immediate, please wait up to twice the value of HeartBtInt (108) for the change to take effect. For example, if the current value of HeartBtInt is 5, please wait up to 10 seconds.
Upon breaching the limit a Reject <3> will be sent containing information about the connection limit breach and the current limit.
FIX Order Entry limits:
- 15 connection attempts within 30 seconds
- Maximum of 10 concurrent TCP connections per account
FIX Drop Copy limits:
- 15 connection attempts within 30 seconds
- Maximum of 10 concurrent TCP connections per account
FIX Market Data limits
- 300 connection attempts within 300 seconds
- Maximum of 100 concurrent TCP connections per account

Unfilled Order Count

To understand how many orders you have placed within a certain time interval, please send a LimitQuery<XLQ> message. A LimitResponse<XLR> message will be sent in response, containing information about Unfilled Order Count and Message Limits.
Please note that if your orders are consistently filled by trades, you can continuously place orders on the API. For more information, please see Spot Unfilled Order Count Rules.
If you exceed the unfilled order count your message will be rejected, and information will be transferred back to you in a reject message specific to that endpoint.
The number of unfilled orders is tracked for each account.

Error Handling

Client messages that contain syntax errors, missing required fields, or refer to unknown symbols will be rejected by the server with a Reject <3> message.

If a valid message cannot be processed and is rejected, an appropriate reject response will be sent. Please refer to the individual message documentation for possible responses.

Please refer to the Text (58) and ErrorCode (25016) fields in responses for the reject reason.

The list of error codes can be found on the Error codes page.

Required fields based on Binance OrderType:

Binance OrderType	Additional mandatory parameters	Additional Information
`LIMIT`	38, 44, 59
`MARKET`	38 OR 152	`MARKET` orders using the `OrderQty (38)` field specifies the amount of the `base asset` the user wants to buy or sell at the market price. E.g. `MARKET` order on BTCUSDT will specify how much BTC the user is buying or selling. `MARKET` orders using `quoteOrderQty` specifies the amount the user wants to spend (when buying) or receive (when selling) the `quote` asset; the correct `quantity` will be determined based on the market liquidity and `quoteOrderQty`. E.g. Using the symbol BTCUSDT: `BUY` side, the order will buy as many BTC as `quoteOrderQty` USDT can. `SELL` side, the order will sell as much BTC needed to receive `CashOrderQty (152)` USDT.
`STOP_LOSS`	38, 1102 or 25009	This will execute a `MARKET` order when the conditions are met. (e.g. `TriggerPrice (1102)` is met or `TriggerTrailingDeltaBips (25009)` is activated)
`STOP_LOSS_LIMIT`	38, 44, 59, 1102 or 25009
`TAKE_PROFIT`	38, 1102 or 25009	This will execute a `MARKET` order when the conditions are met. (e.g. `TriggerPrice (1102)` is met or `TriggerTrailingDeltaBips (25009)` is activated)
`TAKE_PROFIT_LIMIT`	38, 44, 59, 1102 or 25009
`LIMIT_MAKER`	38, 44	This is a `LIMIT` order that will be rejected if the order immediately matches and trades as a taker. This is also known as a POST-ONLY order.

ExecutionReport `<8>`

Sent by the server whenever an order state changes.

[!NOTE]

By default, ExecutionReport<8> is sent for all orders of an account, including those submitted in different connections. Please see Response Mode for other behavior options.

OrderCancelRequest `<F>`

Sent by the client to cancel an order or an order list.

To cancel an order either OrderID (11) or OrigClOrdID (41) are required.
- If both OrderID (37) and OrigClOrdID (41) are provided, the OrderID is searched first, then the OrigClOrdID from that result is checked against that order. If both conditions are not met the request will be rejected.
To cancel an order list either ListID (66) or OrigClListID (25015) are required.
- If both ListID (66) and OrigClListID (25015) are provided, the ListID is searched first, then the OrigClListID from that result is checked against that order. If both conditions are not met the request will be rejected.

If the canceled order is part of an order list, the entire list will be canceled.

Note:

The performance for canceling an order (single cancel or as part of a cancel-replace) is always better when only orderId is sent. Sending origClientOrderId or both orderId + origClientOrderId will be slower.

OrderCancelRequestAndNewOrderSingle `<XCN>`

Sent by the client to cancel an order and submit a new one for execution.

To cancel an order either OrderID (11) or OrigClOrdId (41) are required.
If both OrderID (37) and OrigClOrdID (41) are provided, the OrderID is searched first, then the OrigClOrdID from that result is checked against that order. If both conditions are not met the request will be rejected.

Filters and Order Count are evaluated before the processing of the cancellation and order placement occurs.

A new order that was not attempted (i.e. when newOrderResult: NOT_ATTEMPTED), will still increase the unfilled order count by 1.

Unfilled Order Count: 1

Please refer to Supported Order Types for supported field combinations when describing the new order.

OrderAmendKeepPriorityRequest `<XAK>`

Sent by the client to reduce the original quantity of their order.

This adds 0 orders to the EXCHANGE_MAX_ORDERS filter and the MAX_NUM_ORDERS filter.

Unfilled Order Count: 0

Read Order Amend Keep Priority FAQ to learn more.

Notes:

The ClOrdID (11) is not required to be different from the ClOrdID of the order. When the ClOrdID of the request is the same as the ClOrdID of the order being amended, the ClOrdID will remain unchanged.
If both OrderID (37) and OrigClOrdID (41) are provided, the OrderID is searched first, then the OrigClOrdID (41) from that result is checked against that order. If both conditions are not met the request will be rejected.

MarketDataRequest `<V>`

Sent by the client to subscribe to or unsubscribe from market data stream.

Trade Stream

The Trade Streams push raw trade information; each trade has a unique buyer and seller.

Fields required to subscribe:

SubscriptionRequestType present with value SUBSCRIBE(1)
MDEntryType present with value TRADE(2)

Update Speed: Real-time

Individual Symbol Book Ticker Stream

Pushes any update to the best bid or offers price or quantity in real-time for a specified symbol.

Fields required to subscribe:

SubscriptionRequestType with value SUBSCRIBE(1)
MDEntryType with value BID(0)
MDEntryType with value OFFER(1)
MarketDepth with value 1

Update Speed: Real-time

[!NOTE] In the Individual Symbol Book Ticker Stream, when MDUpdateAction is set to CHANGE(1) in a MarketDataIncrementalRefresh<X> message sent from the server, it replaces the previous best quote.

Diff. Depth Stream

Order book price and quantity depth updates used to locally manage an order book.

Fields required to subscribe:

SubscriptionRequestType with value SUBSCRIBE(1)
MDEntryType with value BID(0)
MDEntryType with value OFFER(1)
MarketDepth with a value between 2 and 5000, which controls the size of the initial snapshot and has no effect on subsequent MarketDataIncrementalRefresh<X> messages

Update Speed: 100ms

[!NOTE] Since the MarketDataSnapshot<W> have a limit on the number of price levels (5000 on each side maximum), you won't learn the quantities for the levels outside of the initial snapshot unless they change. So be careful when using the information for those levels, since they might not reflect the full view of the order book. However, for most use cases, seeing 5000 levels on each side is enough to understand the market and trade effectively.
