老师,请把下面的语句中多头和空头改成点划线:
CCYD:=OPENINT-REF(OPENINT,1);
SPYD:=C-REF(C,1);
多头增仓:IF(SPYD>=0 AND CCYD>=0,ABS(CCYD),NULL),COLOR3232FF,NODRAW;
空头增仓:IF(SPYD<0 AND CCYD>=0,ABS(CCYD),NULL),COLORFFFF54,NODRAW;
STICKLINE(SPYD>=0 AND CCYD>=0,0,-CCYD,0,1,COLORBROWN);//多头
STICKLINE(SPYD<0 AND CCYD>=0,-CCYD,0,0,1,COLORGRAY);//空头
