I'm not a technician either, but I once heard a trader repeat an old adage that has held true as far as I know.
He said, "There is no such thing as a triple top." When pressed to explain, he said that if a stock encounters resistance at a specific point, it is likely to break through the resistance the on the third try.
I checked the index in "Trading for Dummies" my favorite guide on all things "market" & I didn't see any reference to the term "triple top." Do you think this particular trader was the same one who advised you to buy SUPG.
