Newbie: error in the code

[Gepetto]

Hello,

I just discover the power of Automated Trading with NT but I have a problem with the following code at Condition set 3 where the condition does not go through the compiler... To be clear I with to use a SMA of the absolute value of an oscillator... What is the correct syntax?
Thanks in advance

...

Condition set 3
if (SMA(Math.Abs(PriceOscillator(2, 10, 1)),222)[0] >= 0)
{
PlaySound("");
}

Hello,

Is it because Math.Abs() requires a value, not a series.
For example this compiles:
double test = Math.Abs(PriceOscillator(2, 10, 1)[0]);
But this doesn't:
double test = Math.Abs(PriceOscillator(2, 10, 1));

For former refers to a value, and the latter refers to a series.

Easier Way?

OK.
But if Math.Abs() does not accept a series, how to compute a SMA of absolute values of values of an indicator?
Do I need to use a loop to compute one by one the values such that

sum=0;
for (int k = 1; x <= 222; x++)
{
sum = sum + Math.Abs(PriceOscillator(2, 10, 1)[k]);
}
sum=sum/222;

or is there any easier way?

Hello,

I don't think so. I would create a dataseries to store the absolute values, then use that dataseries in your SMA. This link shows how to create a dataseries:
