Phsst,
The return doesn't look so good for RSW. Could you please try comparison
using the following formula instead . I'm not sure that the original formula I
provided should have been as a percent. Maybe it makes a difference ??
// RSWraw = .4*(Total Return 13-Week)+.3*(Total
Return 26-Week)+.3*(TotalReturn 1-Year)tr13 = 0.4 * (C - Ref(C,
-65));tr26 = 0.3 * (C - Ref(C, -130));tr52 = 0.3 * (C - Ref(C,
-260));RSWraw = tr13 + tr26 + tr52;PositionScore = RSWraw;
Sorry to bother you again.
Greg

Ideas
Greg,This backtest comparison is for illustrative
purposes only. I make noclaims regarding these test results other than the
AFL and Setupcriteria was identical for both tests. The only difference
was theassignment of PositionScore = QRS versus PositionScore =
RSW.NOTE: // RSW = .4*(Total Return 13-Week)+.3*(Total Return
26-Week)+.3*(TotalReturn 1-Year)tr13 = 0.4 * (C - Ref(C, -65)) /
Ref(C, -65) * 100;tr26 = 0.3 * (C - Ref(C, -130)) / Ref(C, -130) *
100;tr52 = 0.3 * (C - Ref(C, -260)) / Ref(C, -260) * 100;RSW = tr13 +
tr26 + tr52;PositionScore = RSW;Date Range 6/1/1995 to Present (No
QRS scores exist prior to this)Direct
