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 IDCC 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: August 9, 2022
End date: November 19, 2024
a = 2.4348
b = 0.0014
s = 0.1091
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 68.27%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1091) – 1
= 54.74%

Top border of price channel:
Exp(Y683)
= Exp(a + b × X683 + 2 × s)
= Exp(a + b × 993 + 2 × s)
= Exp(2.4348 + 0.0014 × 993 + 2 × 0.1091)
= Exp(4.0689)
= $58.49
Bottom border of price channel:
Exp(Y683)
= Exp(a + b × X683 – 2 × s)
= Exp(a + b × 993 – 2 × s)
= Exp(2.4348 + 0.0014 × 993 – 2 × 0.1091)
= Exp(3.6323)
= $37.80

= Exp(5.2566)
= $191.83
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(2.4348 + 0.0014 × 1,826 – 2 × 0.1091)
= Exp(4.8200)
= $123.97
