The energy markets are extremely volatile these days, and they might not come to mind as a good arena for demonstrating a relatively basic approach. Quite the contrary, often the markets with the most noise are the ones that benefit most from a simple viewpoint. A simple daily bar chart is a graphic representation of a price range on a given trading day. The highest part of the bar indicates the intraday high. The lowest part of the bar indicates the intraday low. One reason why bar charts work is that trading is a competition. A price at any given moment is a result of this competition. In its simplicity, a bar chart is a good place to start your analysis and a good tool for double-checking your trading decisions. Whether you follow open-high-low-close price bars or high-low-close price bars or candlesticks, the point is to keep in touch with the basics.
