Something similar - LSMA (least squares MA) indicator:

 //calculate LSMA private decimal LSMA(RollingWindow _dataW, int _lsmaPeriod) { decimal _lsma; decimal _delta = 0; //calculate lsma _delta = 0; for(int i=_lsmaPeriod; i >= 1; i--) { _delta += (i-(_lsmaPeriod+1)/3.0m)*_dataW[_lsmaPeriod-i]; } _lsma = _delta*6/(_lsmaPeriod*(_lsmaPeriod+1)); return _lsma; }

I'd like to make this indicator implementation. So, I need to be sure to understand how it works.

Please, can you confirm if I correctly interpreted the code?

$$\delta = \sum_{t=1}^{p}{\left ( i- \frac{p+1}{3} \right ) x_{t}}\\ LSMA = \frac{6 \delta} {p\left ( p+1 \right )}\\$$
where:
$$p$$ is the indicator period.
$$x_t$$ is the price at time $$t$$.

What I've provided I think is end point moving average (EPMA) - endpoint of linear regression. You can Google "Smoothing Techniques For More Accurate Signals pdf" to get article about EPMA.

There are other LSMA versions, like Woodie's LSMA: http://forum.esignal.com/showthread.php?1692-Woodies-LSMA-(Least-Square-Moving-Average)

Correct linear regression MA:

I'll check the sources. Maybe I end up coding both :)

The Accord.NET framework has linear regression. I've used it previously, perhaps it is what you are looking for.
