QuickFIX/Go

Build Status GoDoc Go Report Card

Open Source FIX Protocol library implemented in Go

Getting Started and Documentation

Installation

To install QuickFIX/Go, use go get:

$ go get github.com/andpago/quickfix

Staying up to date

To update QuickFIX/Go to the latest version, use go get -u github.com/andpago/quickfix.

Example Apps

See examples for some simple examples of using QuickFIX/Go.

FIX Message Generation

QuickFIX/Go includes separate packages for tags, fields, enums, messages, and message components generated from the FIX 4.0 - FIX5.0SP2 specs. See:

For most FIX applications, these generated resources are sufficient. Custom FIX applications may generate source specific to the FIX spec of that application using the generate-fix tool included with QuickFIX/Go.

Following installation, generate-fix is installed to $GOPATH/bin/generate-fix. Run $GOPATH/bin/generate-fix --help for usage instructions.

Developing QuickFIX/Go

If you wish to work on QuickFIX/Go itself, you will first need Go installed and configured on your machine (version 1.13+ is preferred, but the minimum required version is 1.6).

Next, using Git, clone the repository via git clone [email protected]:quickfixgo/quickfix.git

Installing Dependencies

As of Go version 1.13, QuickFIX/Go uses modules to manage dependencies. You may require GO111MODULE=on. To install dependencies, run

go mod download

Note: No vendored dependencies are included in the QuickFIX/Go source.

Build and Test

The default make target runs go vet and unit tests.

$ make

If this exits with exit status 0, then everything is working!

Generated Code

Generated code from the FIX40-FIX50SP2 specs are available as separate repos under the QuickFIX/Go organization. The source specifications for this generated code is located in spec/. Generated code can be identified by the .generated.go suffix. Any changes to generated code must be captured by changes to source in cmd/generate-fix. After making changes to the code generator source, run the following to re-generate the source

$ make generate-dist

If you are making changes to the generated code, please create Pull Requests for these changes for the affected repos.

Acceptance Tests

QuickFIX/Go has a comprehensive acceptance test suite covering the FIX protocol. These are the same tests used across all QuickFIX implementations.

QuickFIX/Go acceptance tests depend on ruby in path.

To run acceptance tests,

    # generate code locally
    make generate

	# build acceptance test rig
	make build_accept

	# run acceptance tests
	make accept

Dependencies

If you are developing QuickFIX/Go, there are a few tasks you might need to perform related to dependencies.

Adding/updating a dependency

If you are adding or updating a dependency, you will need to update the go.mod and go.sum in the same Pull Request as the code that depends on it. You should do this in a separate commit from your code, as this makes PR review easier and Git history simpler to read in the future.

  1. Add or update the dependency like usual:
go get -u github.com/foo/bar
  1. Update the module-related files:
go mod tidy
  1. Review the changes in git and commit them.

Note that to specify a specific revision, you can manually edit the go.mod file and run go mod tidy

NewScreenLogFactory creates an instance of LogFactory that writes messages and events to stdout.
NewSessionSettings returns a newly initialized SessionSettings instance.
NewSettings creates a Settings instance.
NewSQLStoreFactory returns a sql-based implementation of MessageStoreFactory.
NewValidator creates a FIX message validator from the given data dictionaries.
ParseMessage constructs a Message from a byte slice wrapping a FIX message.
ParseMessageWithDataDictionary constructs a Message from a byte slice wrapping a FIX message using an optional session and application DataDictionary for reference.
ParseSettings creates and initializes a Settings instance with config parsed from a Reader.Returns error if the config is has parse errors.
RequiredTagMissing returns a validation error when a required field cannot be found in a message.
Send determines the session to send Messagable using header fields BeginString, TargetCompID, SenderCompID.
SendToTarget sends a message based on the sessionID.
TagNotDefinedForThisMessageType returns an error for an invalid tag appearing in a message.
TagSpecifiedWithoutAValue returns a validation error for when a field has no value.
UnregisterSession removes a session from the set of known sessions.
UnsupportedMessageType returns an error to indicate an unhandled message.
