This chart is looking for a potential top in SPX
using fan angles from cloned upward projecting fans. The reference fan for all angles is the upward projecting fan on bottom left. My thoughts are where these lines are concentrated there is resistance until crossed at which time they become support. SPX
is currently sitting just below a concentration of dark blue lines while the light blue lines are acting as support. If we make another run and cross the dark blue lines, next target is the concentration of red lines with a target around 1740.
