macd頂底背離

?

macd:=stkindi('','macd.macd1',0,datatype);

diff:=stkindi('','macd.diff',0,datatype);

底背離:macd<0 and ref(macd,1)<0 and diff>ref(diff,1) and l<ref(l,1);

頂背離:macd>0 and ref(macd,1)>0 and diff<ref(diff,1) and h>ref(h,1);

?

謝謝金老師，怎樣把頂背離，底背離寫到背離點上？

?

macd:=stkindi('','macd.macd1',0,datatype);

diff:=stkindi('','macd.diff',0,datatype);

底背離:macd<0 and ref(macd,1)<0 and diff>ref(diff,1) and l<ref(l,1);

頂背離:macd>0 and ref(macd,1)>0 and diff<ref(diff,1) and h>ref(h,1);

drawtext(底背離,macd,'底背離');

drawtext(頂背離,macd,'頂背離');

怎樣實現區間的llv(diff)與ref（llv（diff），1）的比較？
