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 ACT 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: July 15, 2024
End date: November 20, 2025
a = 3.2203
b = 0.0002
s = 0.0405
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 9.48%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0405) – 1
= 17.60%

Top border of price channel:
Exp(Y709)
= Exp(a + b × X709 + 2 × s)
= Exp(a + b × 1,033 + 2 × s)
= Exp(3.2203 + 0.0002 × 1,033 + 2 × 0.0405)
= Exp(3.5578)
= $35.09
Bottom border of price channel:
Exp(Y709)
= Exp(a + b × X709 – 2 × s)
= Exp(a + b × 1,033 – 2 × s)
= Exp(3.2203 + 0.0002 × 1,033 – 2 × 0.0405)
= Exp(3.3957)
= $29.84

Top border of price channel:
Exp(Y1,050)
= Exp(a + b × X1,050 + 2 × s)
= Exp(a + b × 1,526 + 2 × s)
= Exp(3.2203 + 0.0002 × 1,526 + 2 × 0.0405)
= Exp(3.6802)
= $39.65
Bottom border of price channel:
Exp(Y1,050)
= Exp(a + b × X1,050 – 2 × s)
= Exp(a + b × 1,526 – 2 × s)
= Exp(3.2203 + 0.0002 × 1,526 – 2 × 0.0405)
= Exp(3.5181)
= $33.72
