Code: 
periode = Param("Periode",30,30,50000,1);

bar = BarIndex();
islastbar = bar == BarCount - 1;
isfirstbar = bar == BarCount - periode;

firstbar = LastValue( ValueWhen( isfirstbar, bar ) );
lastbar = LastValue( ValueWhen( islastbar, bar ) );

al = LastValue( ValueWhen( islastbar, LinRegSlope( C, lastbar - firstbar +  1) ) );
bl = LastValue( ValueWhen( islastbar, LinRegIntercept( C, lastbar - firstbar + 1 ) ) );

Lr = al * ( BarIndex() - firstbar ) + bl;
Lr = IIf( bar >= firstbar AND bar <= lastbar , Lr, Null );

se = StdErr(C,lastbar - firstbar);
se = LastValue( ValueWhen( islastbar, StdErr( C, lastbar - firstbar + 1 ) ));

upper = Lr + se;
Lower = Lr - se;

Plot(Lr, "lr", colorYellow, styleThick );
Plot(upper, "upper", colorGreen, styleThick );
Plot(Lower, "lower", colorRed, styleThick );
SetBarFillColor( IIf( C > O, colorBrightGreen, colorRed ) );
Plot(C, "C", colorWhite, styleCandle );

Regression channels

AmiBroker allows to draw easily 3 kinds of regression channels:

Raff regression channel
Standard error channel
Standard deviation channel
All these channels are based on linear regression trend line.

The Regression Channel is constructed by plotting two parallel, equidistant lines above and below a Linear Regression trendline. The distance between the channel lines to the regression line is the greatest distance that any one high or low price is from the regression line.

Standard Error Channels are constructed by plotting two parallel lines above and below a linear regression trendline. The lines are plotted a specified number of standard errors away from the linear regression trendline.

Standard Deviation Channels are constructed by plotting two parallel lines above and below a linear regression trendline. The lines are plotted a specified number of standard errors away from the linear regression trendline.

You can choose the type of channel by double clicking on the Regression channel study (or choosing Properties from right mouse button menu)
