Description:
This function is an EasyLanguage version of the moving average described in the January, 1998 issue of S&C magazine, p.57, "Smoothing Techniques for More Accurate Signals", by Tim Tillson. It is translated from the MetaStock code presented in the article and recoded for efficiency and to allow variable inputs.
The variable, "Hot", is a damping coefficient which is set to the suggested default value of 0.7. The variable "b" is substituted for the variable, "a" used in the article since "a" is a reserved word. The variables e1 through e6 calculate the exponential moving averages in-line rather than calling other functions.
The resulting indicator plotting this function appears to duplicate the results shown in Figure 4 of the article.
The "simple" version of this function must be called on each bar. It should not be put inside a conditional statement where it is only evaluated on some bars.
Inputs:
Price -
Periods -
NOTE: The inputs can be variables or arrays. The "Periods" input can be changed dynamically from bar to bar, if necessary,
and need not be an integer.
EasyLanguage Code:
INPUTS: PRICE(NUMERICSERIES), PERIODS(NUMERICSIMPLE);
VARIABLES: B(0), B2(0), B3(0), E1(PRICE), E2(PRICE), E3(PRICE),
E4(PRICE), E5(PRICE), E6(PRICE), C1(0), C2(0), C3(0),
C4(0), F1(0), F2(0), HOT(0.7);
IF PERIODS + 1 <> 0 THEN BEGIN
IF CURRENTBAR <= 1 THEN BEGIN
B = HOT;
B2 = B * B;
B3 = B * B * B;
C1 = -B3;
C2 = 3 * B2 + 3 * B3;
C3 = -6 * B2 - 3 * B - 3 * B3;
C4 = 1 + 3 * B + B3 + 3 * B2;
END ELSE BEGIN
F1 = 2 / (PERIODS + 1);
F2 = 1 - F1;
E1 = F1 * PRICE + F2 * E1;
E2 = F1 * E1 + F2 * E2;
E3 = F1 * E2 + F2 * E3;
E4 = F1 * E3 + F2 * E4;
E5 = F1 * E4 + F2 * E5;
E6 = F1 * E5 + F2 * E6;
END;
T3AVERAGE.SIMPLE = C1 * E6 + C2 * E5 + C3 * E4 + C4 * E3;
END;
