In this final study an approximation of how much bandwidth one server requires in Saxess and Genium environment was studied. In Saxess it is possible to trade only in so called cash markets, for other financial instruments there are other programs. In Genium it is possible to trade in cash markets and in all the other markets, for example derivates. For the final results to be comparable only cash market traffic was analyzed in Genium. The goal was to determine how much bandwidth was needed for one member server when a certain number of trades were executed.

The study is mostly based on previous studies about stock exchange network and is completely theoretical. Trading and messages sent are explained. These messages generate a certain amount of network traffic and from this traffic a rough bandwidth load approximation was calculated. It must be pointed out that the final result of this study is a rough approximation due to the nature of trading. For each sell order there can be one or for example eight buy orders until a trade execution message is sent.

Saxess is the present trading platform and its technology is not studied here. Genium is the next platform and in this study the basic communication technologies behind it are explained.
