Sorry, the indentations in that code were fine in the Yahoo message
but were not preserved on the post. Let's see if this works:
> function myMA(array, period)
> {
> a = Null;
>
> if (period > 0)
> {
> for (i = period; i < BarCount; i++)
> {
> for (j = 0, temp = 0; j < period; j++)
> {
> temp = temp + array[i-j];
> }
> a[i] = temp / period;
> }
> }
> return a;
> }
>
> Example invocation:
>
> period = Param("Moving Average Period", 15, 1, 50);
>
> array = myMA(Close, period);
>
> Plot(array, "", colorRed);
