I had a friend who was a fanatic about technical analysis. He had a drafting table where he would draw charts by hand with protractors and German machined straight-edges. He was convinced that being half a degree off on the slope of a line would lead you to perdition.
Looking at Bespoke's charts is easier:
With commodities down sharply once again today, and the news media already asking everyone and their mother's if this is the end of the boom, below we highlight our trading range charts of major commodities. The green shading represents two standard deviations above and below the commodity's 50-day moving average. When the price moves above the green shading, it is considered overbought (oversold when below). We provide trend and support lines where necessary.
