How CPR Width Is Classified

Too Narrow CPR (Width % 0 – 0.05% of Pivot) signals a very tight range with strong breakout potential.

Narrow CPR (Width % 0.06% – 0.10% of Pivot) often signals a trending day with potential for breakouts.

Medium CPR (Width % 0.11% – 0.20% of Pivot) may indicate a balanced or transitional session.

Wide CPR (Width % 0.21% – 0.30% of Pivot) often signals a sideways or range-bound day.

Too Wide CPR (Width % 0.31% of Pivot and above) signals a very broad range with low directional conviction.

Formulas Used

Pivot = (H + L + C) / 3
BC = (H + L) / 2
TC = (Pivot - BC) + Pivot

R1 = 2xPivot - L    |   S1 = 2xPivot - H
R2 = Pivot + (H - L)  |   S2 = Pivot - (H - L)
R3 = H + 2x(Pivot - L) |   S3 = L - 2x(H - Pivot)
R4 = R3 + (R2 - R1)  |   S4 = S3 - (S1 - S2)
