He also has another indicator he posted elsewhere, I can re-attach it here. It's called the sweetspot and I don't know if it is specifc to the G-Y, but sure looks like it works well on the G-Y chart.
For example, in one of your attached charts, PipChick, you had drawn a trendline & said if price goes below that, could be short signal .. well that tl intersects with a sweetspot line, giving an "x marks the spot" for price (which looks like it is 203.50)
Check it out... I've got these sweetspot lines on the hourly & daily. I am also using maurizio77's 1 x 5 ema cross on the daily bars as that appears to be very predictive as well. The downside cross just occurred on Friday which further suggests a down move for the g-y. Time will tell
BP seems to be rejecting my attachment .. maybe too large as I added the other multiheat files that I got from the Kreslik site .. will try with just the sweetspot files.
