ATR通道指標公式源碼分享，不過是同花順的公式

M1:=3;M2:=6;M3:=12;M4:=24;

BBI:=(MA(CLOSE,M1)+MA(CLOSE,M2)+MA(CLOSE,M3)+MA(CLOSE,M4))/4;

MTR:=MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW));

ATR:=MA(MTR,14);

U3:BBI+3*ATR;

U2:BBI+2*ATR;

U1:BBI+ATR;

Z:BBI,LINETHICK3;

D1:BBI-ATR;

D2:BBI-2*ATR;

D3:BBI-3*ATR;
