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 CALX 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

a = -2.0195
b = 0.0035
s = 0.0559
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0035) – 1
= 253.17%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0559) – 1
= 25.04%

Top border of price channel:
Exp(Y1,093)
= Exp(a + b × X1,093 + 2 × s)
= Exp(a + b × 1,593 + 2 × s)
= Exp(-2.0195 + 0.0035 × 1,593 + 2 × 0.0559)
= Exp(3.5991)
= $36.57
Bottom border of price channel:
Exp(Y1,093)
= Exp(a + b × X1,093 – 2 × s)
= Exp(a + b × 1,593 – 2 × s)
= Exp(-2.0195 + 0.0035 × 1,593 – 2 × 0.0559)
= Exp(3.3757)
= $29.24
