XJO ETF - need help out of sample testing

Below is a simply 200 day ema cross system for the XJO all ords index.

I'm trying to do some out of sample testing but it just gives me errors, can someone please help me with the code???

I would really like to trade this as a long term strategy but need to confirm the data show with OOS tests. Thanks

nevermind I did it on a spreadsheet.
