What is R|Diamond ??

R-Diamond is the premier technology from Rithmic, but it is not a simple retail solution.
It requires knowledge of programming and the having your own algorithmic solution.
There is the the ability to achieve less than 250µs Tick-to-Trade, but it requires directly hooking up your algorithm to market data and order feed hosted in Rithmic’s data center.
