Disliked{quote} FXCM spreads in demo are differrent from the spreads in real accounts. Sometimes the differences goes even up to more than 20 pips. How on earth can |I rely on such difference?Ignored
Thanks for asking, because it's possible you may have misinterpreted what you saw.
First, it's important to note that FXCM quotes prices to one-tenth of one pip. The difference of "20 pips" that you mentioned might actually be 2 pips. Such a misinterpretation is particularly possible if you are looking at the MT4 platform where 10 points equals 1 pip.
Second, it's important to note that FXCM offers different account types. Mini accounts have an all inclusive spread with no commissions, while Standard accounts have raw FX spreads with a separate commission. This could possibly account for the difference you saw.
Do you have any screenshots? If you send me a private message with the details of your demo and real accounts, I would be happy to check this for you.
