Square weighted MA

[Alexander.Gettinger]

Formulas:
MA=(Sum-SumP*(SumW*Period-SumP*Sum)/(SumP2*Period-SumP*SumP))/Period, where
Sum[i]=Price[i]+Price[i-1]+...+Price[i-Period+1],
SumW[i]=Price[i-1]*1+Price[i-2]*2+...+Price[i-Period+1]*(Period-1),
SumP=1+2+...+(Period-1),
SumP2=1*1+2*2+...+(Period-1)*(Period-1).
