Hi Rich -- Do I understand correctly --- the RAR remains about the same for many runs, each of which had some random noise added to the input price data?
If so, that is generally a good sign -- your system is recognizing and giving buy and sell based on the signal portion of the data, as you asked it to, rather than the noise portion. As always, be sure to perform tests on out-of-sample data that was not used to develop the model.
