REST API

WebSocket API

Introduction

The WebSocket API provides developers a way to access streaming data from our backend engines.

The URLs are:

Using WebSocket API you can:

  1. Access real time price points for products
  2. Reduce the latency introduced by polling the REST API
  3. Access real time Market updates, Balance Updates & Chart updates

Upon connection, if no message is sent via the WebSocket connection (typically not being subscribed to any instrument) within 60 seconds, the connection will be considered idle and will be dropped.

We currently only allow three concurrent WebSocket connections Any new connection that is made that exceeds this limit will cause the disconnection of the oldest WebSocket connection. For example, in the UAT environment: If client A connects, followed by client B, followed by client C, client A will be disconnected. We encourage WebSocket clients to be configured to automatically reconnect in the event of a disconnection.

The WebSocket API provides developers a way to access streaming data from our pricing engines.

Methods

Authentication

For security reasons, IP whitelisting is required to consume our API and whitelists are different for each environment. To authenticate a request, the token key must be included in its Authorization HTTP header. The key must be prefixed by the string literal “Token ”. For instance:

Authorization: Token 9b44b09199c61bcf9416ad846dd0e4

Once authenticated, you will receive a message containing your tradable instruments.

Using Bearer Token

Copy to Clipboard
Request:
    {
       "method":"login",
       "token":"your_bearer_token"
    }

    Response:
    {
       "method":"login",
       "status":"success",
       "message":"Logged in."
    }

To authenticate a request, the bearar token must be included in its Authorization HTTP header.

Using API Keys

Copy to Clipboard
// recvWindow: 45 sec
    Request:
    {
        "method": "login",
        "api": {
            "public_key": "api-public-key",
            "timestamp": 1608028160
        },
        "hmac": "computed-hmac-of-only-api-object"
    }

    Response:
    {
       "method":"login",
       "status":"success",
       "message":"Logged in."
    }

Closing Authenticated Session

Copy to Clipboard
Request:
    {
        "method":"logout"
    }

    Response:
    {
       "method":"logout",
       "status":"success",
       "message":"Logged out."
    }

Subscribing

The WebSocket API works on a subscription model. After subscribing to an event, you will receive the response with status field set to success. Following the subscription, you will receive updates untill you unsubscribe or close the connection.

FIX API

Introduction

This API documentation describes FIX 5.0 (SP2) specification for connecting with Modulus Exchange (Spot). After connecting, logging on, and synchronizing sequence numbers, the client can submit orders.

Download

For your convenience, Modulus maintains our custom dictionary in QuickFIX XML form:

Environment File
Production http://api.modulusexchange.com/uploads/FIX50SP2-Dictionary.zip

Connecting

Modulus's primary trading platform and network point of presence (PoP) is housed in the OVH UK data center in London, United Kingdom. Customers can cross connect from their infrastructure or leverage an approved extranet provider to access Modulus production Market Data feeds, and Order Entry sessions.

Steps to get connected to our FIX infrastructure:

Complete Account Verification

If your firm has not done so already, please complete the Institutional Account Verification Process and obtain our FIX server's IP and Port Number while getting your public IP whitelisted.

Get connected

Once on-boarded as a Modulus customer, generate an API key-pair from your account.

Sandbox and Testing

Modulus operates a Sandbox environment which acts as a replica of our production environment. Modulus strongly recommends that all FIX customers create a Sandbox account to test their workflows. Please follow these steps to get a FIX Sandbox environment setup:

SETUP A SANDBOX ACCOUNT

Create a Sandbox account by going to: https://demo.modulusexchange.com

PERMISSION YOUR TEST IP

E-mail deployment@modulus.io and specify the email address used to setup your Sandbox account and the Source IP that you will be using to connect to the FIX Sandbox. We will respond back once the IP addresses have been enabled. We will also provide you with the Sender and Target CompId that should be used to connect to the test environment.

TEST YOUR WORKFLOW THOROUGHLY

Test all messaging workflows specified in our FIX API documentation. (Modulus currently only supports FIX 5.0 (SP2))

Submitting an order

  1. Client sends server → New Order Single Limit message or a New Order Single Market message
  2. Does Modulus accept the order?
    • Yes, order is accepted for initial processing
      1. Server sends client ← an Execution Report <8> for a new order with:
      2. Is the order marketable?
        • Yes, server executes one or more initial fills
        • Server sends client ← an Execution Report <8> for each fill or partial fill (see below for more details)
        • Does the order have remaining quantity?
          • Yes, server puts the remaining quantity on the book
          • No, server closes the order
        • No, server puts the entire quantity of the order on the book
    • No, order is rejected
      • Server sends client ← an Execution Report <8> indicating the order was rejected with:

Submitting a stop limit order

  1. Client sends server → New Order Single Stop Limit message or with OrdType <40> 4 = Stop Limit, and either a StopPx <99> value less than or equal to Price <44> on a Side <54> 1 = Buy, or a StopPx <99> value greater than or equal to Price <44> on a Side <54> 2 = Sell.
  2. Does Modulus accept the order?
    • Yes, order is accepted for initial processing
      1. Server sends client ← an Execution Report <8> for a new order with:
      2. Has a trade occurred that would trigger your stop order?
        • Yes, the stop order triggers and sends client ← an Execution Report <8> message with the child limit order details.
        • No, the stop order stays hidden and resting until a qualifying trade triggers it, or until the order is cancelled.
      3. Is the order marketable?
        • Yes, server executes one or more initial fills
        • Server sends client ← an Execution Report <8> for each fill or partial fill (see below for more details)
        • Does the order have remaining quantity?
          • Yes, server puts the remaining quantity on the book
          • No, server closes the order
        • No, server puts the entire quantity of the order on the book
    • No, order is rejected
      • Server sends client ← an Execution Report <8> indicating the order was rejected with:

When trades occur

In the event of a partial fill, Modulus sends an Execution Report <8> with:

When the order is completely filled, Modulus sends an Execution Report <8> with:

Canceling an order

  1. Client sends an Order Cancel Request
  2. If successful, Modulus responds with an Execution Report <8> with:
  3. If unsuccessful, Modulus responds with an Order Cancel Reject <9> explaining why the request to cancel the order could not be fulfilled.

Canceling all orders

  1. Client sends an Order Mass Cancel Request
  2. Modulus responds with an Order Mass Cancel Report <35> with:

We only support MassCancelRequestType <530> with value 1 = Cancel orders for a security

Requesting order status

  1. Client sends an Order Status Request
  2. Modulus responds with an Execution Report <8> with:

Supported symbols

The following symbols are valid values for a Symbol <55> field.

Symbols are formatted as BTC_USD where prices are in USD and quantities are in BTC.

Precision on the exchange

Quantity and price on incoming orders are strictly held to the minimums and increments on the table shown above.

However, once on the exchange, quantities and notional values may exhibit additional precision down to two decimal places past the "minimum order increment" listed above. For instance, it is possible that a btcusd trade could execute for a quantity of 0.0000000001 (1e-10) BTC. This is due to:

incoming market orders that may result in partial fills fees holds This additional precision is marketable once on the exchange.

Your account balances are maintained to full fractional precision in each currency.

Identifiers assigned by Modulus

Tag Name Defined in Description
49 SenderCompID Standard Header Assigned value used to identify the firm sending the message.
  • When message is sent from Modulus to the client, Modulus
  • When message is sent from the client to Modulus, the client identifier, e.g. CLIENT-OE
56 TargetCompID Standard Header Assigned value used to identify the firm sending the message.
  • When message is sent from client to Modulus, Modulus
  • When message is sent from the Modulus to the client, the client identifier, e.g. CLIENT-OE
37 OrderID

Globally unique order identifier assigned by Modulus. This order id is assigned to an individual order for the lifetime of the order. When the order appears in an Execution Report <8> with ExecType <150> = 0 = New and OrdStatus <39> = 0 = New, then the order is on the book. In the case of an order cancel reject, the value of this field is NONE.

17 ExecID Globally unique event identifier assigned by Modulus. In context, this event id may refer to any of the following events:
  • order accepted id when the order is on the book
  • trade id for partial fill or fill
  • order cancellation id
  • order rejection id

Standard header

The Standard Header is required on every message.

PossResend <97> is not supported. Modulus will report the last sequence number that the exchange received in the header of the Logon message. The client should assume that any events that the server requests to be replayed have not been acted upon: see Beginning a session for details.

Tag Name Req Description
8 BeginString Y Identifies the beginning of new message and protocol version. Always the first tag in the message.
Valid value:
  • 5.0.SP2
9 BodyLength Y Message length, in bytes, forward to the CheckSum <10> field. Always the second tag in the message.
35 MsgType Y Defines message type. Always the third tag in the message.
34 MsgSeqNum
49 SenderCompID Y Assigned value used to identify the firm sending the message.
43 PossDupFlag N* Indicates possible retransmission of message with this sequence number.
Valid value:
  • Y = Possible duplicate
  • N = Original transmission
*Required for a re-transmitted message.
52 SendingTime Y Time of message transmission (always expressed in UTC).
56 TargetCompID Y Assigned value used to identify the firm receiving the message.
115 OnBehalfOfCompID N* Assigned value used to identify firm originating message if the message was delivered by a third party such as an OMS or OEMS: required when an OMS/OEMS submits or cancels orders on behalf of another Modulus account.
  • Not used or supported in Market Data or single party Order Entry or Drop Copy
  • Third party order entry header usage as follows:
122 OrigSendingTime N* Original time of message transmission (always expressed in UTC) when transmitting orders as the result of a resend request.

*Required for a re-transmitted message.

Standard Trailer

The Standard Trailer is required on every message.

Tag Name Req Description
10 CheckSum Y Three byte, simple checksum. Always the last tag in the message.

Session-Level Messages

Establishing a connection

  1. Client sends server → Logon <A> message
  2. Is client ResetSeqNumFlag <141> to Y?

3. Success! Your FIX connection is established.

When can sequence numbers be reset?

Modulus runs the server side of the FIX connection ("acceptor"). Modulus never resets sequence numbers on the server side during the logon workflow unless the client explicitly requests it.

The client ("initiator") can reset sequence numbers during Logon <A> by setting ResetSeqNumFlag <141> to Y.

Modulus recommends that client consider configuring the FIX initiator to automatically reset sequence numbers under the following conditions:

While synchronizing sequence numbers after a replay, the client may send a Sequence Reset <4> with GapFillFlag <123> = Y in lieu of a replay.

Ending a connection

The client may send the server an optional Logout <5> message but the exchange will not interpret its absence as being an abnormal condition.

Under certain conditions, the server may send the client a Logout <5> message where the Text <58> field contains the reason, such as scheduled maintenance.

Logon <A>

The Logon <A> message must be the first message sent by the application requesting to initiate a FIX session. The Logon <A> message authenticates an institution establishing a connection to Modulus.

Upon receipt of a Logon <A> message, Modulus will authenticate the institution requesting connection by validating Username <553> , SenderCompID <49> and TargetCompID <56> identifying the institution. The server will then issue a Logon <A> message as acknowledgment that the connection request has been accepted. The acknowledgment Logon can also be used by the institution to validate that the connection was established with the correct party. If validation fails, the connection will be dropped without a Reject <2>.

Tag Name Req Description
Standard Header Y MsgType = A
141 ResetSeqNumFlag N Should be set to `Y` when the client wants to indicates that the both sides of the FIX session should reset sequence numbers.
98 EncryptMethod Y Modulus does not support encryption.
Valid value:
  • 0 = None
108 HeartBtInt Y Heartbeat interval in seconds.
Valid value:
  • 30 = 30 seconds
Standard Trailer Y

Heartbeat <0>

The Heartbeat <0> monitors the status of the communication link and identifies when the last of a string of messages was not received. The only supported heartbeat interval, as specified by the Logon <A> message, is 30 seconds.

When either end of a FIX connection has not sent any data for HeartBtInt <108> seconds, it will transmit a Heartbeat <0> message. When either end of the connection has not received any data for ( HeartBtInt <108> + "some reasonable transmission time") seconds, it will transmit a Test Request <1> message. If there is still no Heartbeat <0> message received after ( HeartBtInt <108> + "some reasonable transmission time") seconds then the connection should be considered lost and corrective action be initiated.

Note that a Test Request <1> message can still be sent independent of the value of the HeartBtInt <108>, which will force a Heartbeat <0> message.

Heartbeats issued as the result of Test Request <1> must contain the TestReqID <112> transmitted in the Test Request <1> message. This is useful to verify that the Heartbeat <0> is the result of the Test Request <1> and not as the result of a regular timeout.

Tag Name Req Description
Standard Header Y MsgType = 0
112 TestReqID N* Required when the heartbeat is the result of a Test Request <1> message
Standard Trailer Y

Test Request <1>

The Test Request <1> message forces a heartbeat from the opposing application. The Test Request <1> message checks sequence numbers or verifies communication line status. The opposite application responds to the Test Request <1> with a Heartbeat <0> containing the TestReqID <112>.

The TestReqID <112> verifies that the opposite application is generating the heartbeat as the result of Test Request <1> and not a normal timeout. The opposite application includes the TestReqID <112> in the resulting Heartbeat <0>. Any string can be used as the TestReqID <112> (one suggestion is to use a timestamp string).

Tag Name Req Description
Standard Header Y MsgType = 0
112 TestReqID Y Identifier included in Test Request <1> message to be returned in resulting Heartbeat <0>
Standard Trailer Y

Resend Request <2>

The resend request is sent by the receiving application to initiate the retransmission of messages. This function is utilized if a sequence number gap is detected, if the receiving application lost a message, or as a function of the initialization process.

The resend request can be used to request a single message, a range of messages or all messages subsequent to a particular message.

Note: the sending application may wish to consider the message type when resending messages; e.g. if a new order is in the resend series and a significant time period has elapsed since its original inception, the sender may not wish to retransmit the order given the potential for changed market conditions. (The Sequence Reset <4> - Gap Fill message is used to skip messages that a sender does not wish to resend.)

Note: it is imperative that the receiving application process messages in sequence order, e.g. if message number 7 is missed and 8-9 received, the application should ignore 8 and 9 and ask for a resend of 7-9, or, preferably, 7-0 (0 represents infinity). This latter approach is strongly recommended to recover from out of sequence conditions as it allows for faster recovery in the presence of certain race conditions when both sides are simultaneously attempting to recover a gap.

Sequence Reset <4>

The Sequence Reset <4> message is used in response to a Resend Request <2> message when one or more messages must be skipped over for the following reasons:

Modulus does not support Reset mode ( GapFillFlag <123> not present or equal to N).

Tag Name Req Description
Standard Header Y MsgType = 4
36 NewSeqNo Y New sequence number. The receiver should expect this to be the sequence number of the following message.
123 GapFillFlag Y Indicates that the sender is skipping messages rather than resending them.
