The GOLD (XAUUSDO) down trend, LINEAR REGRESSION chart from 03/1995 to 08/1999 generated a CHANNEL RANGE of $74.
From 08/1999, KEY up side HORIZONTAL support/resistance levels/TARGET PRICES are forward looking (extrapolated) ......PREDICTIVE in nature.....and will be (generally) MULTIPLES of that $74 range.
The chart also highlights that MAJOR share price retracements started at MULTIPLE level of that $74 range and finished at a lower MULTIPLE level of same.......including range mid points.
Cheers.......a test of the ATH @ $2,070 is beckoning (imo).
