What is the formula of "W. Avg % Profit"?

[alexlin]

The help page
does not mention how to calculate "W. Avg % Profit".

And the forum page does not mention the formula of how to calculate "W. Avg % Profit".

For example, I have one row Optimize results as follows:

of winners = 30; # of losers = 56;

W. Tot. Profit = 1873600;
W. Avg. Profit = 62453.33; W. Avg % Profit = 33.94;
L. Tot. Loss = -751400;
L. Avg. Loss = -13417.86; L. Avg % Loss = -7.29;

I've tried to guess how to calculate the "W. Avg % Profit" correctly but failed, such as:
Guess one) W. Avg % Profit
= W. Avg. Profit / W. Tot. Profit * 100
= 62453.33 / 1873600 * 100
= 3.33 (not correct, because the answer is 33.94);

Guess two) W. Avg % Profit
= W. Avg. Profit / (W. Tot. Profit + L. Tot. Loss) * 100
= 62453.33 / (1873600 + -751400) * 100
= 5.56 (not correct, because the answer is 33.94);

Can anyone kindly tell me what the formula for "W. Avg % Profit" is?

Thank you very much!

The help page DOES SAY how it is calculated, quote:

Avg. Profit/Loss %, also known as Expectancy (%) - '(% Profit of winners + % Loss of losers)/(number of trades), represents expected percent gain/loss per trade

It does not matter if it is for all trades, or only winners. Calculation is the same. For winners you just don't include losers, the method is otherwise identical.
