Linear Regression Model

Model equation:
Yi = α + β × Xi + εi

Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)

Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)

where:

i - observation number
Yi - natural logarithm of RBC price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e


Primary Trend

Start date: May 9, 2023
End date: July 14, 2025

a = 4.6424

b = 0.0007

s = 0.0527

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 28.87%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0527) – 1
= 23.48%

Top border of price channel:

Exp(Y709)
= Exp(a + b × X709 + 2 × s)
= Exp(a + b × 1,028 + 2 × s)
= Exp(4.6424 + 0.0007 × 1,028 + 2 × 0.0527)
= Exp(5.4621)
= $235.59

Bottom border of price channel:

Exp(Y709)
= Exp(a + b × X709 – 2 × s)
= Exp(a + b × 1,028 – 2 × s)
= Exp(4.6424 + 0.0007 × 1,028 – 2 × 0.0527)
= Exp(5.2512)
= $190.79

= Exp(6.0159)
= $409.88

Bottom border of price channel:

Exp(Y1,254)
