通达信kdj与boll线结合体公式

n：=9，M1和M2都是3，和系统自带的kdj参数一样

RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
 K:SMA(RSV,M1,1);
 D:SMA(K,M2,1);
 J:3*K-2*D;
 BOLL:MA(J,20),LINETHICK3;
 UPPER:BOLL+2*STD(J,20);
 LOWER:BOLL-2*STD(J,20);
 IF(J>REF(J,1),J,DRAWNULL),COLORRED,LINETHICK2;
 IF(J<REF(J,1),J,DRAWNULL)COLOR00BB00,LINETHICK2;
