R-Quant tools
Fuzzy logic and expert systems
In our experiments as well as in finance we use rather fuzzy definitions such as “high” or “low” which have different numerical value in different situations.
R-Quant implements forward (conclusion) and backward (explanation) chain techniques.
Fuzzy objects may also serve as inputs for neural network applications.

if stock market = US and dollar = up then
if interest rate = down then
