liquibook

Open source limit order book matching engine from OCI

Features

• Low-level components for order matching and aggregate depth tracking
• Memory-efficiency: minimal copying of data to internal structures
• Speed: between 2.0 million and 2.5 million inserts per second. See full performance history.

Flexibility

• Works with or without aggregate depth tracking
• Optional aggregate depth tracking to any number of levels (static) or BBO only
• Works with smart or regular pointers

Works with Your Design

• Preserves your order model, requiring only trivial interface
• Preserves your identifiers for securities, accounts, exchanges, orders, fills
• Use your threading system (or be single-threaded)
• Use your synchronization method

Build Dependencies

• MPC for cross-platform builds
• Assertiv for unit testing
• BOOST (optional) for shared pointer unit testing only

Submodule Note

Assertiv is included as a submodule. After cloning liquibook, you must:

> cd liquibook
> git submodule init
> git submodule update

Linux Build Notes

Make sure the $BOOST_ROOT and $MPC_ROOT environment variables are set, then open a shell

$ cd liquibook
$ . env.sh
$ mwc.pl -type make liquibook.mwc
$ make depend
$ make all

Windows Build Notes

Make sure the %BOOST_ROOT% and %MPC_ROOT% environment variables are set, then open the Visual Studio Command Prompt of choice (this example is for Visual Studio 2010):

> cd liquibook
> winenv.bat
> mwc.pl -type vc10 liquibook.mwc

Then in the same window, start Visual Studio from the command line, opening liquibook.sln

> liquibook.sln

In some cases, you may need to provide the path to Visual Studio - This example is the Visual Studio 2010 Express Edition:

> "%VS100COMNTOOLS%\..\IDE\VCExpress.exe" liquibook.sln

NOTE: If using Visual Studio 2012, you will be asked to upgrade your project. This is because MPC does not yet support -type vc11.
