An Example
Suppose you want to trade CFDs, where the underlying asset is the US10YR, known as ‘’US 10yr T-Note” Let us suppose that the US10YR is trading at BID 130.62 ASK 131.76
You decide to buy 100 contracts of US10YR because you think that the US10YR price will rise in the future. Your margin rate is 1%. This means that you need to deposit 1% of the total position value into your margin account.
1% x (100 x 131.76) = 131.76 USD
In the next hour, if the bond price moves to 132.3/133.2, you have a winning trade. You could close your position by selling at the current (bid) price of US10YR, which is 132.3.
( 100 x (132.3 – 131.76) = 54 USD
