Anyone Algo trading?

I have started to dip my tows in calgo
I've managed to make a fairly simple forex setup over the last week or so
Its a simple ema cross with an RSI and Stochastics and trailing stops
My goal is to eventually emulate my actual swing trading (minus the speculating)

anyway...
I am curious about what a good results should look like when back testing?

I'm sitting at about a 4:1 profit ratio with a max drawdown of 0.2- 0.3%
profit ends up being about 6-8% per year

hopefully it improves once i can learn to define support and resistance areas
