The main parameter, which indicates how successful Strategy Provider is, is "Profitability". In CopyMarkets system, "Profitability" is calculated according to the following formula:
P = ( (Equity_end_1 / Equity_begin_1) * (Equity_end_2 / Equity_begin_2) * ... * (Equity_end_N / Equity_begin_N) - 1) * 100%
where:
P – profitability (profit) in %.
Equity_begin_X – equity at the start of X period.
Equity_end_X – equity at the end of X period X.
N – the latest of the periods, taken into account for calculations.
The periods are divided by balance operations. The formula calculates the profitability in % since the moment of account opening or the moment of total loss of funds (when the Equity is less or equal zero). Please note, that withdrawal of all funds from the account (Equity is zero) is not considered as the total loss of funds.
