指标编写需要有具体的思路，论坛方便提供思路上的建议请你理解
这里以3楼精华帖中的编写为例，可以参考：
DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:EMA(DIFF,9);
MACD:2*(DIFF-DEA),COLORSTICK;
JC:=CROSS(DIFF,DEA);
SC:=CROSSDOWN(DIFF,DEA);
N1:=BARSLAST(JC)+1;
N2:=BARSLAST(SC)+1;
HH:=VALUEWHEN(CROSSDOWN(DIFF,DEA),HHV(H,N1));//上次MACD红柱期间合约最大值
HH2:=VALUEWHEN(CROSSDOWN(DIFF,DEA),REF(HH,1));//上上次MACD红柱期间合约最大值
MHD:=VALUEWHEN(CROSSDOWN(DIFF,DEA),HHV(MACD,N1));//上次MACD红柱期间MACD最大值
MHD2:=VALUEWHEN(CROSSDOWN(DIFF,DEA),REF(MHD,1));//上上次MACD红柱期间MACD最大值
LL:=VALUEWHEN(CROSS(DIFF,DEA),LLV(L,N2));//上次MACD绿柱期间合约最小值
LL2:=VALUEWHEN(CROSS(DIFF,DEA),REF(LL,1));//上上次MACD绿柱期间合约最小值
MLD:=VALUEWHEN(CROSS(DIFF,DEA),LLV(MACD,N2));//上次MACD绿柱期间MACD最小值
MLD2:=VALUEWHEN(CROSS(DIFF,DEA),REF(MLD,1));//上上次MACD绿柱期间MACD最小值
A:=CROSSDOWN(DIFF,DEA)&&HH>HH2&&MHD<MHD2;//顶背离
B:=CROSS(DIFF,DEA)&&LL<LL2&&MLD>MLD2;//底背离
DRAWICON(A,MACD,5);
DRAWICON(B,MACD,4);
