网友求助：
DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
A2:=BARSLAST(REF(CROSS(DIFF,DEA),1));
VAR2d:=(CLOSE*2+HIGH+LOW)/4;
N1G:=CLOSE/REF(CLOSE,1)>=1.097 AND HIGH=CLOSE AND NOT(OPEN=HIGH);
A1G:=BARSLAST(N1G);
A2G:=LLV(LOW,A1G-1)>REF(LOW,A1G) AND CLOSE/REF(OPEN,A1G)>1 AND CLOSE/REF(OPEN,A1G)<=1.04;
XGGG:=FILTER(A2G,3) AND A1G>=4 AND A1G<=20;
MA20:=MA(CLOSE,20);
XPP1:=CROSS(DEA,DIFF) AND CLOSE>MA20 AND MA20>REF(MA20,1) AND DIFF>REF(DIFF,A2+1);
DRAWTEXT(XPP1,LOW*0.98,'洗盘'),COLORWHITE;
解答如下：
DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MA20:=MA(CLOSE,20);
XP:CROSS(DEA,DIFF) AND CLOSE>MA20 AND MA20>REF(MA20,1) AND DIFF>REF(DIFF,A2+1);
