Spot Trading Versus Futures Trading
by Anonymous
The main difference between spots and futures is the actual delivery of currency. In futures, the price is settled when the contract is signed and the currencies are exchanged. In the spot forex, the price is determined at the point of trade, and the physical exchange of the currencies takes place at that moment or within a short period of time. Although, many futures traders tend to close out their positions before the contract expires.
