Common to every system: hourly bars only (regular session, volume > 0) · wave count window = last 300 bars · pivots need ≥5 bars per segment · waves need ≥3 bars · wave 2 shorter than wave 1 · wave 4 never overlaps wave 1 (an "alternate" count relaxes the overlap rule when the strict one finds nothing) · Elliott Oscillator = SMA((H+L)/2, 5) − SMA((H+L)/2, 35) · pullback index = 100 / (1 + VPR), VPR = (w4 move × w4 volume) / (w3 move × w3 volume).
