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 CHTR 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: August 30, 2022
End date: July 25, 2025
a = 5.9035
b = 0.0000
s = 0.1307
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= -0.92%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1307) – 1
= 68.65%

Top border of price channel:
Exp(Y491)
= Exp(a + b × X491 + 2 × s)
= Exp(a + b × 712 + 2 × s)
= Exp(5.9035 + 0.0000 × 712 + 2 × 0.1307)
= Exp(6.1467)
= $467.15
Bottom border of price channel:
Exp(Y491)
= Exp(a + b × X491 – 2 × s)
= Exp(a + b × 712 – 2 × s)
= Exp(5.9035 + 0.0000 × 712 – 2 × 0.1307)
= Exp(5.6240)
= $277.00

Top border of price channel:
Exp(Y1,218)
= Exp(a + b × X1,218 + 2 × s)
= Exp(a + b × 1,772 + 2 × s)
= Exp(5.9035 + 0.0000 × 1,772 + 2 × 0.1307)
= Exp(6.1197)
= $454.72
Bottom border of price channel:
Exp(Y1,218)
= Exp(a + b × X1,218 – 2 × s)
= Exp(a + b × 1,772 – 2 × s)
= Exp(5.9035 + 0.0000 × 1,772 – 2 × 0.1307)
= Exp(5.5970)
= $269.63
