If a trading strategy makes money continously for the last 6 years with 40% annualized return, what should I make out of it ? Is it really that GEM of a strategy OR is it a BUG in my code and I am living in a fantasy world. Have been struggling for the past 4 days. Hope to answer the question soon. I don’t wish anything as of now..Just want to see some correct numbers, even if the numbers turn out to fantastic or pathetic :)

Update: It was a bug:) . Numbers underform the SPY..arggg!
