请教怎样改成以下公式。

Mov(CLOSE,3,E);Mov(CLOSE,5,E);Mov(CLOSE,8,E);Mov(CLOSE,10,E);Mov(CLOSE,12,E);

Mov(CLOSE,15,E);Mov(CLOSE,30,E);Mov(CLOSE,35,E);Mov(CLOSE,40,E);Mov(CLOSE,45,E);

Mov(CLOSE,50,E);Mov(CLOSE,60,E);

Smoothed Moving Average (SMMA)Smoothed Moving Average (SMMA)
The first value of this smoothed moving average is calculated as the simple moving average (SMA):
SUM1 = SUM(CLOSE, N)SMMA1 = SUM1/N
The second and succeeding moving averages are calculated according to this formula:
PREVSUM = SMMA(i-1) *NSMMA(i) = (PREVSUM-SMMA(i-1)+CLOSE(i))/N
Where:
SUM1 — is the total sum of closing prices for N periods;
PREVSUM — is the smoothed sum of the previous bar;
SMMA1 — is the smoothed moving average of the first bar;
SMMA(i) — is the smoothed moving average of the current bar (except for the first one);
CLOSE(i) — is the current closing price;
N — is the smoothing period.

谢谢！

上面的問題, 好似剪貼後掽合起一樣,
似問非問, 似公式非公式........  勁 ~~

上面那埋想怎樣的???   中途斷開就接入 ...........Smoothed Moving Average (SMMA)Smoothed Moving Average (SMMA)......

"Mov(CLOSE,3,E);Mov(CLOSE,5,E);Mov(CLOSE,8,E);Mov(CLOSE,10,E);Mov(CLOSE,12,E);

Mov(CLOSE,15,E);Mov(CLOSE,30,E);Mov(CLOSE,35,E);Mov(CLOSE,40,E);Mov(CLOSE,45,E);

Mov(CLOSE,50,E);Mov(CLOSE,60,E);"

 SUM1 = SUM(CLOSE, N)SMMA1 = SUM1/N  ?????????

 

 

 咁樣........ 我無法明你想點架喎..............

你睇我都從網上抄了類似的資料:

Smoothed Moving Average (SMMA)

The first value of this smoothed moving average is calculated as the simple moving average (SMA):

SUM1 = SUM(CLOSE, N)
SMMA1 = SUM1/N

The second and succeeding moving averages are calculated according to this formula:

SMMA(i) = (SUM1-SMMA1+CLOSE(i))/N

Where:
SUM1 — is the total sum of closing prices for N periods;
SMMA1 — is the smoothed moving average of the first bar;
SMMA(i) — is the smoothed moving average of the current bar (except for the first one);
CLOSE(i) — is the current closing price;
N — is the smoothing period.

"Mov(CLOSE,3,E);Mov(CLOSE,5,E);Mov(CLOSE,8,E);Mov(CLOSE,10,E);Mov(CLOSE,12,E);

Mov(CLOSE,15,E);Mov(CLOSE,30,E);Mov(CLOSE,35,E);Mov(CLOSE,40,E);Mov(CLOSE,45,E);

Mov(CLOSE,50,E);Mov(CLOSE,60,E);"

除這一埋唔知你想問乜以外, 其它的只要簡單的跟著所須要的條件一一輸入便可以做到 !!

{Smoothed Moving Average (SMMA)}
nDay     :=Input("Please enter the N periods:",1,1000,10);
SUM1    :=Sum(CLOSE,nDay);
SMMA1 :=SUM1 /nDay;
SMMA   :=(SUM1-SMMA1+CLOSE)/nDay;
SMMA

 

完成 - 可以調較 N periods 的 SMMA 技術指標 !!
