A direct translation is:

DSS = XAverage(XAverage(Close - Lowest(Close, p1), p2), p3) / 
      XAverage(XAverage(Highest(Close, p1) - Lowest(Close, p1), p2), p3)

But TradeStation may not be able to parse it correctly.

This version is probably safer:

Value1 = Close - Lowest(Close, p1);
Value2 = XAverage(Value1, p2);
Value3 = XAverage(Value2, p3);

Value4 = Highest(Close, p1) - Lowest(Close, p1);
Value5 = XAverage(Value4, p2);
Value6 = XAverage(Value5, p3);

if Value6 <> 0 then 
   DSS = Value3 / Value6;
