• Date: Indicates the two initial dates used to draw the regression line on intraday charts.
• Time: Indicates the two initial times used to draw the regression line on intraday charts.
• Price: Price used to draw the regression lines. Choices include: Open, High, Low,
Close, Mid, HLC/3, and Average.
• Limit Lines: Sets how the standard error channel lines are constructed. Choices
include: Factor x Std Err, Factor x Residuals, and Max Deviation.
Standard Error = MLR(@,period) + Factor * StdDev(@,period)
Residual = MLR(@,period) + Factor * SqRoot(MLRResidual(@,period)/(period-1))
with n-1 as divisor
Max Deviation = The close that is furthest from the linear regression line.
• Factor: Number of standard errors between the limit lines, if the Limit Lines parameter
is set to Factor x Std Err. Otherwise, this setting has no effect on the display.
• Divisor: N = a standard deviation calculation; N-1 = population standard deviation
calculation.
• Length: Determines the range covered by the regression lines. Choices include:
From point 1 to point 2, point 1 to point 2 and onward, point 2 to point 1 and onward,
and backward from point 1 to forward from point 2.
• Update: Number of minutes between recalculations. If set to zero, the study recalculate
after every tick. Setting the study to recalculate after every tick allows the two reference
points to remain a constant number of bars apart.
• ScaleLabel: Select this checkbox to color-code the price scale according to the trend
line.
