My trade on the NZDUSD resulted in a win. I used a 1.25:1 reward:risk ratio when trading with the trend.
Since going live at the start of September, my equity has grown by 5%. If annually-adjusted, that should mean a performance of 17% p.a.
I've used various levels of risk, from 1% to 5% per trade. I found 5% risk to be quite high, particularly for mechanical trading. I've reduced my last few trades to 1% risk or less and found it much more comfortable - in fact I forget I have trades open at this level. The key to winning mechanically = low risk * high frequency. It's the high frequency part I need to focus on.
