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 BWA 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: April 3, 2025
End date: September 17, 2025
a = -1.9319
b = 0.0031
s = 0.0411
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0031) – 1
= 214.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0411) – 1
= 17.88%

Top border of price channel:
Exp(Y1,140)
= Exp(a + b × X1,140 + 2 × s)
= Exp(a + b × 1,658 + 2 × s)
= Exp(-1.9319 + 0.0031 × 1,658 + 2 × 0.0411)
= Exp(3.3526)
= $28.58
Bottom border of price channel:
Exp(Y1,140)
= Exp(a + b × X1,140 – 2 × s)
= Exp(a + b × 1,658 – 2 × s)
= Exp(-1.9319 + 0.0031 × 1,658 – 2 × 0.0411)
= Exp(3.1882)
= $24.24

= Exp(3.8766)
= $48.26
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
