That's about the time that many firms go into bot trading, thus making more stocks running like the indices themselves in real-time. Thus, you get more extreme readings in broad market advance issues than before.Quote from originalskunk:
Which is a very interesting coincidence considering that the system was shown to the wider public in the December 2000 issue of Active Trader magazine.

Taking that into account, the system still performs well for another 2 years before its performance peter out. I don't think you can get this type of performance easily, especially in a publicly released system.
p.s. I sure hope my 3-days advance issues model published in Futures magazine (Jan 08 issue) will beat this record!

it is here and now....keep up the good work anek....you have been an inspiration to me...
