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 KRYS 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 27, 2022
End date: September 6, 2024
a = 2.6988
b = 0.0014
s = 0.1158
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 66.59%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1158) – 1
= 58.89%

Top border of price channel:
Exp(Y664)
= Exp(a + b × X664 + 2 × s)
= Exp(a + b × 961 + 2 × s)
= Exp(2.6988 + 0.0014 × 961 + 2 × 0.1158)
= Exp(4.2741)
= $71.81
Bottom border of price channel:
Exp(Y664)
= Exp(a + b × X664 – 2 × s)
= Exp(a + b × 961 – 2 × s)
= Exp(2.6988 + 0.0014 × 961 – 2 × 0.1158)
= Exp(3.8110)
= $45.20
