KILLED · arbitrary
Hypothesis
W.D. Gann’s geometric angles (1×1, 2×1) and "squaring price and time" identify support/resistance and turning points.
Math
$$ \text{1×1 angle: } \Delta \text{price} = \Delta \text{time}\ \text{(in chosen, arbitrary units)} $$
Method
Tested Gann-angle support/resistance and time-squares with mechanized rules on multiple unit scalings.
Results
| Dependence on arbitrary unit scaling | total |
| Edge over random trendlines | none |
Gann methods depend entirely on an arbitrary price/time unit scaling chosen to make the geometry "work". Equating dollars with bars has no economic meaning. No edge over random lines. Killed.
Geometry on a price chart only means something if the axes have a fixed, justified scale. Free units let you draw any conclusion you want.
