20 years ago I published the 1st Oddball trading system in a magazine called Active Trader. Prior to being published a variation of it was used at Regal Asset Management in Dallas for over a decade running on a Ned Davis trading platform called Technalyzer. In base system form, it's a foundation to build upon and there have been many other more successful variations published by various trading system developers. For a base model it has held up well. The idea behind Oddball is that it does not use the data it trades in the calculation of the buy - sell signal. It uses only the NYSE Advancing Issues to determine the buy - sell signals. Simply elegant and an always in model, it trades only natural hour from 9-3 day session only yet holding overnight and weekends, undaunted it has remained profitable with no re-optimization of the original inputs published 20 years ago.
