Profit directions: (a-duh)

	Profit Direction	Loss Direction
Selling	Down	Up
Buying	Up	Down

As for the trailing stops, If thats the way their being executed, I would consider that 'wrong' because most people would head into a trailing stop thinking it works the way I described, and the text (that at least used to be found on Bitcoinica) to explain the functionality of the trailing stop was not contrary to that.
If the trailing stop is to be used at all then the way it executes will have to be outlined on the site.
Although it does just sound like a programming error, having the stop price change with every price change rather than just the overall price change, I cant see a time when an order executing like that would be beneficial. I reckon this should be fixed.
Im testing a position too: Trailing stop buy at $50
