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 MLM 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: February 28, 2024
End date: April 28, 2025
a = 7.0089
b = -0.0004
s = 0.0516
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -14.78%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0516) – 1
= 22.93%

Top border of price channel:
Exp(Y964)
= Exp(a + b × X964 + 2 × s)
= Exp(a + b × 1,400 + 2 × s)
= Exp(7.0089 + -0.0004 × 1,400 + 2 × 0.0516)
= Exp(6.4988)
= $664.32
Bottom border of price channel:
Exp(Y964)
= Exp(a + b × X964 – 2 × s)
= Exp(a + b × 1,400 – 2 × s)
= Exp(7.0089 + -0.0004 × 1,400 – 2 × 0.0516)
= Exp(6.2923)
= $540.40

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(7.0089 + -0.0004 × 1,825 + 2 × 0.0516)
= Exp(6.3126)
= $551.45
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(7.0089 + -0.0004 × 1,825 – 2 × 0.0516)
= Exp(6.1061)
= $448.59
