In terms of slope, hopefully a slope will inform one how to read the charts. The only exception would be the "Flat Line Slope", a slope with less than a +/- .10 reading, which is indicating that a certain type of price behavior exist or will occur. For Monday 4/9 we have an obvious positive slope. In other words price lows will occur below the slope and price highs above the slope. In the following example let's revisit the Amazon 2018 Weekly Price Chart which has an obvious negative slope. With the negative slope price highs will be below the slope and price lows will occur above the slope.
