Al_Dente, I've been playing around for months with that currency pair on stockcharts for future prediction, but I have no clue how Tom McClellan creates his chart. As you can see from my below chart, it's the only closest thing that I got. So far, it's able to predict major market collapses in advance from last 3-year. At the present, it shows there isn't any major market collapse in this year, except some corrections starting in the middle of June this year.
If you are interested to play around with my chart or my idea, I'd be happy to share with you the settings of this chart.
