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 MAT 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: March 10, 2021
End date: August 18, 2025
a = 3.1011
b = -0.0001
s = 0.0889
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0001) – 1
= -4.08%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0889) – 1
= 42.72%

Top border of price channel:
Exp(Y139)
= Exp(a + b × X139 + 2 × s)
= Exp(a + b × 203 + 2 × s)
= Exp(3.1011 + -0.0001 × 203 + 2 × 0.0889)
= Exp(3.2557)
= $25.94
Bottom border of price channel:
Exp(Y139)
= Exp(a + b × X139 – 2 × s)
= Exp(a + b × 203 – 2 × s)
= Exp(3.1011 + -0.0001 × 203 – 2 × 0.0889)
= Exp(2.9000)
= $18.17

Top border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(3.1011 + -0.0001 × 1,825 + 2 × 0.0889)
= Exp(3.0705)
= $21.55
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(3.1011 + -0.0001 × 1,825 – 2 × 0.0889)
= Exp(2.7148)
= $15.10
