Hi Bhoza,
Yup, sorry an honest mistake.
I’m not sure if you coming at this from a stock market perspective where shorting is a vastly different operation from going long? Nevertheless, there is absolutely no difference in margin requirement for going short vs going long.
The initial margin does vary with the exchange rate(so small that I haven’t really noticed it before) but it is the same for long and short. It does not change after you enter the trade.
Bear in mind that going long or short is exactly the same thing. 2 sides of the same coin if you will. In the trade you are always buying one currency and selling another. If you sell EURUSD, you are selling EUR but at the same time you are buying USD. Conversely if you buy EURUSD, you may be buying EUR but you are selling USD to do it.
To clarify about account currency it simply means if you buy or sell when your account currency is EUR and you trade EURxxx, then exchange rate does not feature in the calculation and is, therefore, always the same.
