The chart below is a perfect example. The developing value area (DVA) is straddling the overlapping Value Area Low (VAL). Will it go into the previous VA or will price develop value lower? The bar chart tells that story as it reveals itself.
Looking at the bar chart, the picture is clear. Price is in a down trend and rallies must be sold. Short term scalping traders will cover and reshort. Slightly longer term traders will stay short and add to shorts until support is reached or until the market tells them they are wrong.
Each trader has a so called "style" which determines the rhythm of their trading and the types of trades they carry out.
