To small to make out the price points and not of the same scale. Don't know why this 1980 chart does not show the high at 50. Looking at the four price points they are close. We are also getting close to the duration from the 1980 high until its final death plunge below about 34. Yep not the same, but they could be cousins.
Hey looks like Wayne's instructions worked. Tried using your chart Trades, but when I went to upload everyting it said it was to big.
