Strategies can never keep up unless there is low latency processing of data feeds as well as historical databases. Since forex caters to an over the counter type of market, there are specific logistical hurdles that come with the package, adding to the challenges. The industry's solution is called stream processing, a brand new way of processing data. Even real time streaming data can now be computed and can execute queries like stored data because of stream processing. Programming languages such as C++ & Java have traditionally been used by coders to create real time analytical applications.

High development costs come as the outcome of using custom coding and low level tools.

Risk taking models shall perform more fundamental analysis and be capable of responding automatically to the events fed to it from electronic information sources.
