Well, it stood me in good stead for a long time. Had thought about posting in this forum and wrote up something recently, but didn't want it to get moved to Trading Systems so waited quite a while to hear from FF about whether they would wnat to move it. Guess will go ahead and post it anyway - probably you won't like it all that much Hanover, it's definitely not quantitative, except in the workings of the indicator, of course.
