A Moving Average calculated by the least squares method.

The indicator has two input parameters:

• Period - calculation period;
• Applied price - price used for calculations.

Sum[i] = (Period - N)*Price[i] + (Period - N - 1)*Price[i-1] + … + (1 - N)*Price[i-Period+1],  N = (Period + 1)/3,  L2 = Period*(Period + 1)/6
