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 CALM 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 26, 2024
End date: January 27, 2025
a = -0.4508
b = 0.0028
s = 0.0480
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0028) – 1
= 181.36%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0480) – 1
= 21.18%

Top border of price channel:
Exp(Y1,069)
= Exp(a + b × X1,069 + 2 × s)
= Exp(a + b × 1,550 + 2 × s)
= Exp(-0.4508 + 0.0028 × 1,550 + 2 × 0.0480)
= Exp(4.0382)
= $56.72
Bottom border of price channel:
Exp(Y1,069)
= Exp(a + b × X1,069 – 2 × s)
= Exp(a + b × 1,550 – 2 × s)
= Exp(-0.4508 + 0.0028 × 1,550 – 2 × 0.0480)
= Exp(3.8460)
= $46.81
