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 FIX 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: February 27, 2025
End date: February 24, 2026
a = -0.0312
b = 0.0040
s = 0.0781
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0040) – 1
= 326.54%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0781) – 1
= 36.67%

Top border of price channel:
Exp(Y1,006)
= Exp(a + b × X1,006 + 2 × s)
= Exp(a + b × 1,463 + 2 × s)
= Exp(-0.0312 + 0.0040 × 1,463 + 2 × 0.0781)
= Exp(5.9391)
= $379.58
Bottom border of price channel:
Exp(Y1,006)
= Exp(a + b × X1,006 – 2 × s)
= Exp(a + b × 1,463 – 2 × s)
= Exp(-0.0312 + 0.0040 × 1,463 – 2 × 0.0781)
= Exp(5.6266)
= $277.73
