DDY漲跌動(dòng)因修正指標(biāo) 公式

作者：大智慧來源：cxh99.com 發(fā)布時(shí)間：2023年04月16日

這段代碼繪制了漲跌動(dòng)因指標(biāo)，漲跌動(dòng)因指標(biāo)可以反映市場熱度變化程度。該指標(biāo)主要是通過多個(gè)指標(biāo)計(jì)算來得出。

具體的操作建議，當(dāng)漲跌動(dòng)因指標(biāo)處于高位的時(shí)候，說明市場熱度較高，其股票的漲跌幅度也相對較大，此時(shí)可以選擇逢高賣出；當(dāng)漲跌動(dòng)因指標(biāo)處于低位時(shí)，說明市場活躍度不高，股票漲跌幅度也相對較小，此時(shí)可以選擇逢低買入。

DDY中用了ema算法，但是理想數(shù)據(jù)是單個(gè)數(shù)據(jù)（只有當(dāng)日數(shù)據(jù)，沒有ema可言）。這就需要把ema解析后改寫。
原公式：{lx-ddy}

INPUT: P1(60,0,100),P2(5,0,100),P3(10,0,100);
REFLINE:0;
TODAY:=DYNAINFO(7)=CLOSE and DYNAINFO(10)=AMOUNT and (ORDER(1)=0 and ORDER(2)=0);
{判斷是否有理想數(shù)據(jù)}
RDDY1:=IF(TODAY,"DDEDATA@BIGORDER"(1),bigorder(1));
RDDY2:=IF(TODAY,"DDEDATA@BIGORDER"(2),bigorder(2));
FDDY1:=IF(TODAY,"DDEDATA@ORDER"(1),ORDER(1));
FDDY2:=IF(TODAY,"DDEDATA@ORDER"(2),ORDER(2));
VAR0:=MIN(COUNT(FDDY2,0),P1);
VAR1:=EMA((2 - RDDY1 - RDDY2) * VOL/(FDDY1 + FDDY2),p1);
DDY:(FDDY2 - FDDY1)/CAPITAL * VAR1 * 100,COLOR3D;
DDY1:EMA((FDDY2 - FDDY1)/CAPITAL * VAR1 * 100,VAR0) * VAR0;
DDY2:MA(DDY1,P2);
DDY3:MA(DDY1,P3);
DRAWTEXTABS(0,0,'漲跌動(dòng)因');
1,DOTLINE;注意這句：
VAR1:=EMA((2 - RDDY1 - RDDY2) * VOL/(FDDY1 + FDDY2),p1);變成-----（用法:EMA(X,N),算法：若Y=EMA(X,N)則Y=[2*X+(N-1)*Y']/(N+1),其中Y'表示上一周期Y值）：
VAR1:=EMA((2 - BIGORDER(1) - BIGORDER(2)) * VOL/(ORDER(1) + ORDER(2)),P1);
VAR2:=(2*(2 - BIGORDER(1) - BIGORDER(2)) * VOL/(ORDER(1) + ORDER(2))+(p1-1)*ref(VAR1,1))/(p1+1);
VAR11:=if(TODAY,VAR2,VAR1);
　修正ema后的公式：
{DDY}
INPUT: P1(60,0,100),P2(3,0,100),P3(10,0,100);
REFLINE:0;
TODAY:=DYNAINFO(7)=CLOSE and DYNAINFO(10)=AMOUNT and (ORDER(1)=0 and ORDER(2)=0);
VAR0:=MIN(COUNT(ORDER(2),0),P1);
VAR1:=EMA((2 - BIGORDER(1) - BIGORDER(2)) * VOL/(ORDER(1) + ORDER(2)),P1);
VAR2:=(2*(2 - BIGORDER(1) - BIGORDER(2)) * VOL/(ORDER(1) + ORDER(2))+(p1-1)*ref(VAR1,1))/(p1+1);
VAR11:=if(TODAY,VAR2,VAR1);
DDY:if(TODAY,("DDEDATA@ORDER"(2) - "DDEDATA@ORDER"(1))/CAPITAL ,(ORDER(2) - ORDER(1))/CAPITAL) * VAR11 * 100,COLOR3D;
DDY1:EMA(DDY,VAR0) * VAR0;
DDY2:MA(DDY1,P2);
DDY3:MA(DDY1,P3);
