Infrequent Nibbles

I'm getting into this small position size infrequent trading style.For example, with a pittance of my capital at risk I am earning nearly a 5% annual return. What am I trading? I'm holding the ever popular AUDJPY carry trade pair of course.Even with the recent wildfires in Australia I really don't see them falling off the map completely. Come on, realistically, how low can their dollar sink?
