N := 20;  {线性回归周期}
M := 2;   {通道倍数}

{计算线性回归}
Slope := LINREGSLOPE(CLOSE, N);
Intercept := LINREGINTERCEPT(CLOSE, N);
LinearReg := Intercept + Slope * (N - 1);

{计算标准差通道}
StdDev := STD(CLOSE, N);
UpperChannel := LinearReg + M * StdDev;
LowerChannel := LinearReg - M * StdDev;

{价格位置}
PricePosition := (CLOSE - LowerChannel) / (UpperChannel - LowerChannel) * 100;

{买入信号：价格从下向上突破中轨}
BuySignal := CROSS(CLOSE, LinearReg) AND Slope > 0;

{卖出信号：价格从上向下跌破中轨}
SellSignal := CROSS(LinearReg, CLOSE) AND Slope < 0;

{突破上轨加仓信号}
AddPosition := CLOSE > UpperChannel AND REF(CLOSE, 1) <= UpperChannel;

{止损信号：价格跌破下轨}
StopLoss := CLOSE < LowerChannel;

{输出信号}
DRAWICON(BuySignal, LOW * 0.98, 1);
DRAWICON(SellSignal, HIGH * 1.02, 2);
DRAWICON(AddPosition, LOW * 0.98, 23);
DRAWICON(StopLoss, HIGH * 1.02, 12);

{绘制通道}
LINESTREG: LinearReg, COLORWHITE, LINETHICK2;
UPPER: UpperChannel, COLORGREEN, LINETHICK1;
LOWER: LowerChannel, COLORRED, LINETHICK1;

{填充通道区域}
FILLRGN(UpperChannel, LowerChannel, Slope > 0), COLORRGB(0, 100, 0);
FILLRGN(UpperChannel, LowerChannel, Slope < 0), COLORRGB(100, 0, 0);

{交易提示文字}
DRAWTEXT(BuySignal, LOW * 0.96, '买'), COLORYELLOW;
DRAWTEXT(SellSignal, HIGH * 1.04, '卖'), COLORGREEN;
DRAWTEXT(AddPosition, LOW * 0.96, '加'), COLORYELLOW;
DRAWTEXT(StopLoss, HIGH * 1.04, '止损'), COLORRED;

{风险警示}
RiskWarning := PricePosition > 80 OR PricePosition < 20;
DRAWTEXT(RiskWarning, HIGH * 1.06, '风险'), COLORRED;

{参数设置}
N, 5, 60, 20;
M, 1, 5, 2;
