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: March 28, 2024
a = 1.9600
b = 0.0016
s = 0.1116
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 77.54%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1116) – 1
= 56.27%

Top border of price channel:
Exp(Y819)
= Exp(a + b × X819 + 2 × s)
= Exp(a + b × 1,188 + 2 × s)
= Exp(1.9600 + 0.0016 × 1,188 + 2 × 0.1116)
= Exp(4.0515)
= $57.48
Bottom border of price channel:
Exp(Y819)
= Exp(a + b × X819 – 2 × s)
= Exp(a + b × 1,188 – 2 × s)
= Exp(1.9600 + 0.0016 × 1,188 – 2 × 0.1116)
= Exp(3.6050)
= $36.78

Top border of price channel:
Exp(Y1,230)
= Exp(a + b × X1,230 + 2 × s)
= Exp(a + b × 1,785 + 2 × s)
= Exp(1.9600 + 0.0016 × 1,785 + 2 × 0.1116)
= Exp(4.9903)
= $146.98
Bottom border of price channel:
Exp(Y1,230)
= Exp(a + b × X1,230 – 2 × s)
= Exp(a + b × 1,785 – 2 × s)
= Exp(1.9600 + 0.0016 × 1,785 – 2 × 0.1116)
= Exp(4.5439)
= $94.05
