There 
seems to be something radically wrong with your stats 
(below):
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>1.   Both of them show nice annual returns 
(89-140%).
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>2.   Yet, the average p/l is negative 
(2-4%).
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>3.   The Sharpe ratio is negative.
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>4.   The average win is 3%.
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>5.   The average loss is 10-11%.
<FONT face=Arial color=#0000ff 
size=2> 
What's 
the story???

  PositionScore IdeasGreg,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
