求助修改一个实时预警公式

预警公式对盘中30分钟K线图上的DIF在0轴之上上拐或DIF在0轴之下下拐发出预警。下面的公式如何修改？谢谢！DIFF:=EMA(CLOSE,S) - EMA(CLOSE,P);DEA:=EMA(DIFF,M);MACD:=2*(DIFF-DEA);// 判断DIF上拐和下拐DIF上拐 := DIFF > REF(DIFF, 1) AND REF(DIFF, 1) <= REF(DIFF, 2);DIF下拐 := DIFF < REF(DIFF, 1) AND REF(DIFF, 1) >= REF(DIFF, 2);// 预警条件预警DIF上拐0轴之上: DIF > 0 AND DIF上拐, ALERT('DIF在0轴之上上拐，发出预警');预警DIF下拐0轴之下: DIF < 0 AND DIF下拐, ALERT('DIF在0轴之下下拐，发出预警');

DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
MACD:=2*(DIF-DEA);
cond:dif>0 and cross(macd,0)

你好，我向要的是DIF线上拐，就是新一根K线比前一根高，前一根比更前一根低。不是要上穿0轴的

技术008

DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
MACD:=2*(DIF-DEA);
cond:dif>0 and dfii>ref(diff,1)

前一根DIF比更前一根低怎么写代码？

ref(diff,1)<ref(diff,2)
