how can 90% be losers? if going long one currency means going short another, that implies there is a buyer and a seller.
it takes 2 people to make a market and for every winner there is a loser....hence this 90% thing does not make sense.
obviously the practice of
FX trading is a bit more complex than this as many corporations/individuals will not be trading
FX for profit. ie it will also comprise buying and selling of products/services, hedging......
but my intial point re 90% are losers does not make sense!
