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

Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
