I completed the course earlier this year. Settled on a monthly rotational system that trades the R1000. I found that keeping parameter settings simple & generic worked best. I only optimised the index filter length. System uses volatility adjusted position sizing. I found having 2 versions of the system one for backtesting & then another for operations useful in terms of having the operational parameters set.
Results over the test period were CAR 17.9% with max DD 16.4% for the system I adopted. Went live with the system in March. Results so far:
Mar: 1.41%
Apr: 1.62%
I also trade the growth portfolio. For 2019 to Apr 3.9%.
