>As for your correlation of indicators, the original article that I know
was published by Lukac, Brorsen, and Irwin, "Similarity of Computer Guided
Technical Trading Systems," CSFM-124, Working Paper Series, Columbia
Futures Center, Columbia University Business School, 1986. It compared 12
systems for correlation of returns, percentage of trades that occurred on
the same day, and the percentage of trading days that the systems held the
same positions. This was picked up by Futures Magazine in November 1987 as
"Do similar signals from trading systems move prices?" Of course, it
couldn't answer that question from the information in the article. I'm
familiar with this because I covered it in my book, "The New Commodity
Trading Systems and Methods", and have upgraded that coverage in the third
edition, coming out in late October. Therefore, the most accessible
write-up would be in my book.

>>>I can't remember if it was in a book or in Futures mag...does anyone
recall a book/article where they tested 20-30 indicators and then ranked
their correlation. It turned out that many of the indicators were highly
correlated. I'd like to re-read the article if anyone else can remember
what that was from.
