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 ADI 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 22, 2024
End date: February 18, 2025
a = 5.9175
b = -0.0003
s = 0.0314
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.90%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0314) – 1
= 13.37%

Top border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 + 2 × s)
= Exp(a + b × 1,513 + 2 × s)
= Exp(5.9175 + -0.0003 × 1,513 + 2 × 0.0314)
= Exp(5.5018)
= $245.14
Bottom border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 – 2 × s)
= Exp(a + b × 1,513 – 2 × s)
= Exp(5.9175 + -0.0003 × 1,513 – 2 × 0.0314)
= Exp(5.3764)
= $216.24

Top border of price channel:
Exp(Y1,227)
= Exp(a + b × X1,227 + 2 × s)
= Exp(a + b × 1,785 + 2 × s)
= Exp(5.9175 + -0.0003 × 1,785 + 2 × 0.0314)
= Exp(5.4158)
= $224.94
Bottom border of price channel:
Exp(Y1,227)
= Exp(a + b × X1,227 – 2 × s)
= Exp(a + b × 1,785 – 2 × s)
= Exp(5.9175 + -0.0003 × 1,785 – 2 × 0.0314)
= Exp(5.2904)
= $198.42
