能不能提前算出明天要涨多少MACD才金叉？

山丘村长先生的公式：

黄线是金叉死叉反推价，白线是diff反推价，紫线是macd反推价。

各代码如下：

参数： short(12,1,100,1) long(26,1,100,1) M(9,1,100,1)

DIFF :=EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);
DEA  :=EMA(DIFF,M);
MACD :=2*(DIFF-DEA);
jcsc:=(M-1)/(M+1)*dea/(1-2/(m+1));{计算出金叉死叉时的Diff值}
dd:=(macd/2+(dea*(m-1)/(M+1)))/(1-2/(m+1));{计算出明日macd=macd时的Diff值}
xx:(diff*(short+1)*(long+1)-(long+1)*(short-1)*ema(c,short)+(short+1)*(long-1)*ema(c,long))/(2*((long+1)-(short+1)));{计算今日Diff=diff的对应股价}
js:(jcsc*(short+1)*(long+1)-(long+1)*(short-1)*ema(c,short)+(short+1)*(long-1)*ema(c,long))/(2*((long+1)-(short+1)));{计算金叉死叉的对应股价}
ddd:(dd*(short+1)*(long+1)-(long+1)*(short-1)*ema(c,short)+(short+1)*(long-1)*ema(c,long))/(2*((long+1)-(short+1)));{计算macd柱体变向时的对应股价}
