[amibroker] Question regarding position score

["fsmart21" <jdgeddie@xxxxxxxxx>]

How can I assign a different position score for buy and short trades 
within the same formula?

Current PS:

PositionScore =ValueWhen( Cross( PDI(n), MDI(n) ), RSI(n2), 0);

This works fine for buy orders, but not short orders.  Need this PS 
for short:

PositionScore =ValueWhen( Cross( PDI(n), MDI(n) ), 100-RSI(n2), 0);

But how do I build this into one formula?

Right now my short signals are being ranked based on the highest RSI, 
but I need them ranked on lowest RSI.

Thanks,

John
