Forex-prediction curve-fitting time-series artificial-neural-networks differential-evolution C Updated Mar 25, 2018 A library for fitting functions to sets of data. And for those of you who wondered what happened to the. When testing the system on the past data, the testing may show 5,000 in profits when using a 10 day high/low, 10,000 in profits when using a 20 day high/low, and 20,000 when using a 30 day high/low. This gives us more confidence in selecting the final strategies to take into live testing. The problem is, just because one parameter worked on the past data does not mean it will work on the future, unknown data.
