I have no clue how to upload the indicator so I'll just post the coding.

[LegacyColorValue = true];
{Updated by DJ Reda on Sat 4/16/05
Added option to use either Standard Deviation or Standard Error of Estimate to plotchannel bands}
{ // Note: Setting a begin date that is earlier than the amount of length for the regression
will produce an extend to the left model that is date and time restricted
The End Date must not be in the future // }

inputs:
STD1_SEE2(2),
Length ( 50), { // Length of Linear Regression // }
Size(1),//Trend Line Thickness
BeginDate ( 0), { // Choose Zero to use full length // }
BeginTime ( 0), { // Choose Zero to use full time // }
EndDate ( 0), { // Choose Zero for Current Day // }
EndTime ( 0), { // Choose Zero for Current Time // }
NumDevsUp ( 2), { // Standard deviations for upper // }
NumDevsDn ( -2), { // Standard deviations for lower // }
LRColor ( Green), { // Color for Linear Regression Line // }
STDDevColor( Magenta), { // Color for Upper Boundary // }
SEEColor(Magenta) , { // Color for Lower Boundary // }
ExtRight ( false), { // Set to true to extend to right // }

This indicator was sent to me from Pat B. from TTM

LRC

I'd attach some screen shots of how I use the LRC, but I have no clue what I'm doing.
