Stochastic oscillator What about graphs of closing price, high and low on same axes?

[#1]

According to Wikipedia (on stochastic oscillator) the idea behind this indicator is that prices tend to close near their past highs in bull markets, and near their lows in bear markets. If i drew 3 graphs of, say agl, one of closing price, one of high and one of low on the same axes, it seems this would benefit me. Any comments?
