Initial margin requirement
The initial margin requirement is the amount of money required to open a position in a given market through a brokerage. It is usually represented as a percentage of the total amount you seek to open as a position. A trader looking to trade £100,000 in the forex market place may pay £10,000 to a brokerage as a 10% initial margin requirement and would still get the total £100,000 exposure through the brokerage.
How do I calculate the initial margin requirement?
You can calculate the initial margin requirement by multiplying the margin percentage by the purchase price of a given asset. The margin percentage may differ depending on the market and the leverage offered by your brokerage. In a simplified example, you are looking to buy £100,000 worth of a security through a brokerage that requires an initial margin of 50%, your initial margin requirement will cost £50,000.
