He said the reason was based on his computer studies done on first big
computer at purdue, not ease of computation. But since I did thousands of
hand drawn charts with a slide rule and then a calculator, I know an easy

out as a stock goes up the mountain.
If an indicator beats Dahl, use it. You could even pass it on.
