Just a side note. Anyone that talks about support and resistance is full of crap. This falls under the category, it works until it doesn't, and there always be a time when it doesn't. There are no consistent rules on how, when and where to draw those lines. Everyone does it different. Take a look at the chart in the article. Partially cover the right side of the chart so you don't see the most recent prices. Now draw a resistance line. Yeah, anyone can do it. Now ask yourself the question, how should trade given your line? It is what every magic you see in that bull shit line. Btw, I rely on technical analysis when I trade.
Sorry for the rant. This is just one of pet peeves when it comes to non-traders writing about investing. It is a Wall Street thing to confuse and take advantage of the masses.
One of my big pet peeves is when people draw longer term support support and resistance without factoring in the currency valuation differences.
