# of Random-Space Tests
Random space performs a WF over the entire oscillator range. Genetic performs WF over a smaller range relative to the initial oscillator values.
If you don't use Genetic Algorithm Walk-Forward (WF), this figure (10,000 in the Example) is the amount of tests. 10,000 or more for 3 indicator system recommended. If repeated identical WF results very a lot with identical parameters, increase this figure.
Default WF method is Genetic Algorithm, not random space.
