This is a simple application of MOB using Clojure, a modern Lisp dialect with rich functional programming support.

MOB enables you to operate MetaTrader4, a popular algorithmic trading platform, via arbitrary RDBMS. See the link for more details.

MOB obviously requires a RDBMS that has its ODBC driver. Popular ones are MySQL, PostgreSQL, SQLite, etc. For Java programming language, there are decent RDBMS implementations like HSQLDB, Derby, and H2 database. Those can be run as a stand-alone server as well as an embedded database inside your application, and you may get some advantages by using the same programming languages with the database and your application.

Especially H2 database has good features comparing to other databases. And important point for MOB application, it can talk PostgreSQL protocol so that you can use PostgreSQL’s ODBC driver.

MOB4Clojure adopts H2 database as the server side. And it also provides some handy client side functions to operate MT4 over MOB. Both sides can be in the same process, because H2 database is embeddable, so that you can integrate them tightly if you want. For example, you can write a database trigger that manipulates arbitrary Java objects without network IO.
