主题：同时有多单又有空单，帮忙检查下哪里错了

//开多
DK1:=CROSS(C,MA20) AND D1 ;//AND C>=D3
DK2:=CROSS(DIFF,0) AND D2 ;//AND C>=D3
 
DMA20:=VALUEWHEN(CROSS(C,MA20),MA20);//向上突破20均线时，取20周期均线的值
DJC:=DMA20+N1*MINDIFF;//进场价格为均线上N3个变动单位

//开空
KK1:=CROSS(MA20,C) AND K1 ;
KK2:=CROSS(0,DIFF) AND K2 ;

KMA20:=VALUEWHEN(CROSS(MA20,C),MA20);
KJC:=KMA20-N2*MINDIFF;

//VERTLINE(D2),COLORRED;
//VERTLINE(KP1),COLORGREEN;
//
ADK:=DK1 OR DK2;
AKK:=KK1 OR KK2;
//开仓
BUY(ADK AND HOLDING=0,1,LIMITR,DJC);
buyshort(AKK AND HOLDING=0,1,LIMITR,KJC);

//多头平仓
DCC:=KMA20-N3*MINDIFF;
DP1:=CROSS(DCC,L) ;
//空头平仓
KCC:=DMA20+N4*MINDIFF;
KP1:=CROSS(H,KCC) ;
//平仓
多方出场:sell(DP1 AND HOLDING>0,1,LIMITR,DCC);

空方出场:sellshort(KP1 AND HOLDING<0,1,LIMITR,KCC);
