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 CRVL 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 9, 2025
End date: September 30, 2025
a = 8.5985
b = -0.0023
s = 0.0334
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0023) – 1
= -56.92%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0334) – 1
= 14.30%

Top border of price channel:
Exp(Y1,135)
= Exp(a + b × X1,135 + 2 × s)
= Exp(a + b × 1,651 + 2 × s)
= Exp(8.5985 + -0.0023 × 1,651 + 2 × 0.0334)
= Exp(4.8563)
= $128.54
Bottom border of price channel:
Exp(Y1,135)
= Exp(a + b × X1,135 – 2 × s)
= Exp(a + b × 1,651 – 2 × s)
= Exp(8.5985 + -0.0023 × 1,651 – 2 × 0.0334)
= Exp(4.7226)
= $112.46
