Bin doing some interesting analysis in Excel on my Investor Challenge trades. Turns out that if I had used only R100 000 starting from 03 January I would've lost it all by the end of May. So I entered all the shares again using the R100 000 and just 2 simple moving averages which meant trading the shares on different dates but withing the January to May period and managed to turn the 102% loss into a 16.6% gain. So I thought, surely I can do better than that, so I added the ZAR/USD exchange rate which excluded 11 shares and turned the 16.6% into 89.1%. Tried different combinations of indicators, including the popular ones, and still ended up with a loss.
Edit: turned the 16.% into 58.3%
