If you have ever been exposed to business or watched the business news you may have heard about bridging loans. This is a short term loan used to tide your business over for a short period. Payday advance loans are similar but available to the public rather than a business but they have the same purpose, to keep you going financially when cash is short.
When foreign currency trading you may come to a point where you need cash to make a trade but all your money is tied up. You can get cash advance loans to temporarily cover for that period of financial short fall. This is a quick way of getting cash.
Gearing is a term you also may have come across, it basically means you borrow money to invest to make more money. The idea is your profit covers the interest of your cash advance and leaves you with some profit.
You could use this method if you were sure of a movement in the market in your favour. Rather than trading a hundred dollars and getting 10 dollars profit you could get a cash advance loan of a thousand dollars and make 100 dollars profit. You would then use that 100 dollars to pay of the loan interest and pocket the rest as profit.
