Ok, the reason I'm posting this is because I'm new to system development, so I don't even know what is good or what means anything. So I've been tinkering with system development for a while now, and I've come up with a system that returns about 200% a year on stocks, no margin, 1% of total capital risked per trade and about 5% max dd. The system is only about 6 lines of code, so it's extremely simple. It's got about 50% more winners than losers, and avg. winner is about 5X the avg. loser. I've backtested it back to 1997. The system trades a 5 min chart. The above results seem too good to be true. Have I found something spectacular? Or do most system developers have systems like this hidden in their drawers? Do these results have any chance of working in the real world? BTW, the reason the stats are so rough is because stockwatch pro doesn't give you many stats on the results page and I don't have excel to do all the calculations. So for max dd, I just eyed up the results manually and did what I could on Microsoft spreadsheet.
