将这个底背离选股公式改成通达信的选股公式

编写条件：

{底背离} {INPUT:N(20,0,80);} {1.MACD} DIFF :=EMA(CLOSE,7) - EMA(CLOSE,13); DEA := EMA(DIFF,3); MACD := 2*(DIFF-DEA); A1:=BARSLAST(REF(CROSS(DIFF,DEA),1)); B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)C AND REF(K,A2+1)C AND REF(RSI1,A3+1)REF(CCI4,1) AND CROSS(CCI4,-100); { CCI底背离'} XG:((B1 AND B2) OR (B2 AND B3) OR (B1 AND B3) OR ( B4 AND CCI4<-90) ) AND D编写方法：
