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 IBKR 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: September 21, 2023
End date: February 13, 2026
a = 1.4496
b = 0.0016
s = 0.0951
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0016) – 1
= 79.80%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0951) – 1
= 46.30%

Top border of price channel:
Exp(Y653)
= Exp(a + b × X653 + 2 × s)
= Exp(a + b × 946 + 2 × s)
= Exp(1.4496 + 0.0016 × 946 + 2 × 0.0951)
= Exp(3.1603)
= $23.58
Bottom border of price channel:
Exp(Y653)
= Exp(a + b × X653 – 2 × s)
= Exp(a + b × 946 – 2 × s)
= Exp(1.4496 + 0.0016 × 946 – 2 × 0.0951)
= Exp(2.7799)
= $16.12
