I ran some tests that I thought the group may find interesting. My software has the ability to paratest multiple parameters similar to GTR1. I tested the Dying Bullish Euphoria using two indexes as the basis of the signals, and fourteen indexes for the returns off of these two indexes. The two indexes for producing the signals was NDX100 and the S&P 500.

Here are the indexes

Symbol  Index
^XCI    Amex Computer
^NDX    Nasdaq 100 Index
^PSE    Tech: Pse Tech
^IXIC   Nasdaq Composite
^IXID   Nas - Nms Industrial
^XII    Institutional Ndx
^OEX    S&P 100
^RUI    Russell 1000
^RUA    Russell 3000
^GSPC   S&P 500
^XAX    Amex Composite
^IXFN   Nas - Nms Financial
^MID    S&P Mid Caps
^DJI    Dow Jones Industrial Average

This should explain why I use a longer lookback. Using the NDX100 to produce the signals significantly improves on the returns no matter which index you use for actual investing.
