Refers to the foreign exchange spot contract, which belongs to the spot category, but it is still different from the traditional spot. First of all, this does not involve the delivery problem, that is to say, the position you trade will not be exchanged for the real corresponding currency delivery. Secondly, the contract transaction, that is, the margin transaction, is not a full transaction, but you can conduct the full transaction by paying a certain margin to the broker. Also known as margin trading. There is no actual demand at all, it is purely a category of speculative trading.
