What is the problem with the exchange at the limit price of currencies? In currencies, whenever we try to exchange them for dollars, the demand does not get executed quickly, and sometimes it takes a whole day. Is the currency exchange done directly between two people on the platform, or is it the platform management that handles the currency exchange in this way? In other words, is this direct buying and selling between two individuals on the platform, or is there a third party acting as an intermediary between them?
