Z-Score

[Icham Aidibe]

Hi,

Regarding the formula of the Z Score (found @ https://www.mql5.com/en/articles/1492),

Z=(N*(R-0.5)-P)/((P*(P-N))/(N-1))^(1/2)

where:
N - total amount of trades in a series;
R - total amount of series of profitable and losing trades;
P = 2*W*L;
W - total amount of profitable trades in the series;
L - total amount of losing trades in the series.

For such a series (the one at the top) : 

We'll use :

N = 34
R = 5 (2 + / 3 -)
P = 2*W*L;
W - total amount of profitable trades in the series; <---- for W & L, is it the total amount of win deals & loss deals, in a way that : W+L = 34 ? 
L - total amount of losing trades in the series.

Correct ?
