Thanks Muel, it's close... but OTC and NAZ don't exactly mirror each other. OTC market does its own little thing, like the Pigs can Fly 2000, my index chart got that, the drop right after March is fast and steep (this matches with what I remember), but the steepest and fastest drop came between Oct and End of 2000.
I think my index is tracking the whole OTC market correctly, now I'm just finding the right "Negative Pulse Factor" for the index.
