Hi Charlie,
In back testing, short selling is not yet supported. I am hopeful that this feature will be available soon.
Regarding TRIX system, I see there is a problem with it's definition. Instead of EMA(9) it should be EMA(9)[TRIX], basically cross over of TRIX with its EMA should be used. I will fix this and update soon.
