Disliked{quote} Nonsense. A loan is legally and financially created each time you trade on margin. {quote} True, at least technically. But what you conveniently "forgot" to mention is that the loss could be quite, quite substantial and in some cases even exceed your trading capital 10 or 50 times over (think SNB massacre, for instance).Ignored
Brokers want deposits before they allow you to trade, because they do not want to give out any loans. They will close out positions if you no longer have money to support difference between trade origination rate and the current exchange rate. In rare circumstances, the deposit may not be enough, but that is entirely different issue from the issue of loan being made for you to originate a trade.
