The original msg:
Classic Formula

R4 = R3 + RANGE (same as: PP + RANGE * 3)
R3 = R2 + RANGE (same as: PP + RANGE * 2)
R2 = PP + RANGE
R1 = (2 * PP) - LOW
PP = (HIGH + LOW + CLOSE) / 3
S1 = (2 * PP) - HIGH
S2 = PP - RANGE
S3 = S2 - RANGE (same as: PP - RANGE * 2)
S4 = S3 - RANGE (same as: PP - RANGE * 3)

But I have another site telling me:
Classic Formula

R3 = R1 + RANGE
R2 = PP + RANGE
R1 = (2 * PP) - LOW
PP = (HIGH + LOW + CLOSE) / 3
S1 = (2 * PP) - HIGH
S2 = PP - RANGE
S3 = S1 - RANGE

Can anyone tell me the difference? (R3 and S3) Or if one is better than the other?
