Anyway, angles do work but I rely more on channels, consistent angle speeds, and arc distances, than intersecting angles...which can be off by a mile if used wrong. Try using the angles more on the dailies. TEST to see if they hit major and medium top to bottoms, and bottom to tops, before you decide they are right. SCALE is crucial when using angles. If it's wrong you'll be using a 30 degree angle and it's showing up at 38 degrees on the chart.
Ignore the prediction accuracy in this chart. It was a test for 15 min charts...and I am not satisfied with the angles. Way too fast.
