MACD公式源碼:
DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);
DEA : EMA(DIFF,M);
MACD : 2*(DIFF-DEA), COLORSTICK;
由源碼可知，MACD的重點(diǎn)是在于快速EMA與慢速EMA的差值。
通過(guò)反向推算MACD中Diff，設(shè)其明日的值與今天的值相等，便能更好的把握多空能量發(fā)生改變時(shí)的價(jià)位。
EMA=【2x+（N-1）*EMA’】/(N+1);
那么可以得于
明日diff=今日Diff的時(shí)候
股價(jià):=(diff*(short+1)*(long+1)-(long+1)*(short-1)*ema(c,short)+(short+1)*(long-1)*ema(c,long))/(2*((long+1)-(short+1)));
我們?cè)贛ACD的原碼里加入兩行:
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)));
drawtextabs(5,5,'Diff轉(zhuǎn)向:'+xx);
同理，我們也可以反推出MACD金叉和死叉里的價(jià)格。
有同學(xué)想知道金叉死叉的價(jià)格，實(shí)際上其實(shí)沒(méi)有太大操作意義。（詳見(jiàn)圖2）
根據(jù)MACD的值變化反推出來(lái)的價(jià)格線反而更具操作意義。
黃線是金叉死叉反推價(jià)，白線是diff反推價(jià)，紫線是macd反推價(jià)。
各代碼如下：
參數(shù)： 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));{計(jì)算出金叉死叉時(shí)的Diff值}
dd:=(macd/2+(dea*(m-1)/(M+1)))/(1-2/(m+1));{計(jì)算出明日macd=macd時(shí)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)));{計(jì)算今日Diff=diff的對(duì)應(yīng)股價(jià)}
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)));{計(jì)算金叉死叉的對(duì)應(yīng)股價(jià)}
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)));{計(jì)算macd柱體變向時(shí)的對(duì)應(yīng)股價(jià)}
