Iff Function Different Averages

[andypap 10]

can anybody explain why this two averages have different values?

regards

this is the code:

 

 

Inputs: Price ©,Period (30);

vars : val(0);

 

if BarType >= 2 then val= volume else val = ticks;

 

value1 = iff (Momentum (Price, 1) > 0,

momentum(price,1)*val, 0.0001);

value2 = average(value1,period);

value3 = Average (iff (Momentum (Price, 1) > 0,

momentum(price,1)*val, 0.0001), Period);

plot1(value2);

plot2(value3);

[Tams 20]

value3 = Average (iff (Momentum (Price, 1) > 0, momentum(price,1) * val, 0.0001), Period);

 

because the current value of val is used for every iteration of the "average" calculation.

thanks in advance for the reply..

you mean this average summation is the following

 

momentum(price,1)*val + momentum(price,1)[1] *val to period instead

momentum(price,1)*val + momentum(price,1)[1] *val[1] to period ..

 

maybe i havn't understood though.

I don't understand what you are talking about either.

 

just use plot1 and you won't have the problem.

[andypap 10]

Inputs: Price ©,Period (30);

vars : val(0),return(0);

 

if BarType >= 2 then val= volume else val = ticks;

 

 

if 100 - 100 /

(1 + Average (iff (Momentum (Price, 1) > 0,

Momentum (Price, 1) * val, 0), Period) /

Average (iff (Momentum (Price, 1) < 0,

-1 * Momentum (Price, 1) * val, 0), Period)) <> 0

then Return = 100 - 100 /

(1 + Average (iff (Momentum (Price, 1) > 0,

Momentum (Price, 1) * val, 0), Period) /

Average (iff (Momentum (Price, 1) < 0,

-1 * Momentum (Price, 1) * val, 0), Period)) ;

 

 

if 100 - 100 /

(1 + Average (iff (Momentum (Price, 1) > 0,

Momentum (Price, 1) * val, 0), Period) /

Average (iff (Momentum (Price, 1) < 0,

-1 * Momentum (Price, 1) * val, 0), Period)) = 0

 

then Return = .0001;

 

plot1(return);

 

the code above is the original indicator..gives floating point errors when period<30..

i try to simplify the code by the following lines

 

 

vars :prval(0),plusval(0);

 

prval = c-c[1];

if prval > 0 then

plusval = prval*val else plusval = 0;

 

 

 

value1 = iff (Momentum (Price, 1) > 0,

momentum(price,1)*val, 0);

 

value2 = average(value1,period);

 

value3 = Average (iff (Momentum (Price, 1) > 0,

momentum(price,1)*val, 0), Period);

 

plusval and value1 are exactly the same so do their averages value2 and the eqivelent average of plusval..

value3 plots slightly different values..

but these is the segment of the original code..

so i was wondering why the average

of the iff value(value2) is different than value3..

i was thinking maybe there is something between these two statments worth exploring

 

thanks for your patience

you should wrap codes inside code tags.

 

see the # symbol in the reply box.
