Can someone help me with the problem showing on the following code? line 6 between period and close I dont have any knowlege regarding coding and have created this code using chatGTP. Many thanks.
// Set the period for calculation
period = 50
// Calculate linear regression line
slope = LinearRegressionSlope[period](close)
intercept = LinearRegressionIntercept[period](close)
regression_line = intercept + slope * BarIndex
// Calculate standard error
sum_squared_errors = 0
for i = 0 to period – 1 do
predicted = intercept + slope * (BarIndex – i)
sum_squared_errors = sum_squared_errors + (close[i] – predicted)^2
next
std_error = sqrt(sum_squared_errors / period)
// Upper and lower channel lines
upper_channel = regression_line + std_error
lower_channel = regression_line – std_error
// Plot the lines
RETURN regression_line AS “Regression Line”, upper_channel AS “Upper Channel”, lower_channel AS “Lower Channel”
