A spot trade is a method of trading foreign exchange currency. Spot trades, also called cash trades, are foreign exchange trades with immediate delivery. The name spot trade came to be because this type of trade is generally made on the spot.. Some countries have laws that limit how long it takes for the delivery from a spot trade to reach the purchaser, often legally limiting the time between the trade and delivery to within one or two days.

They are really a jumbled mess made up of millions and millions of pieces of ice and rock, ranging in size from tiny grains of dust to chunks bigger than a house.
