From the 1st of December, 2010 year the hedged margin will be changed. According to the Company decision, hedged margin will be 30% of the cumulative margin.
For instance, 1.0 lot buy order on USDCHF with 1:1000 leverage is hedged by 1.0 sell lot on the same currency pair.
Cumulative margin will be:
Margin for buy order + Margin for sell order = 100 USD + 100 USD = 200 USD.
Hedged margin will be:
(Margin for buy order + Margin for sell order) = (100 USD + 100 USD)*30% = 60 USD.
As a result, for 2 orders in the opposite direction with the same lot hedged margin will be 30% of the cumulative margin.
