How to calculate margin for a specific CFD position?

You need to multiply the volume of this position by the contract size, multiply the resulting value by the current market price, then multiply by the margin percentage. For example, when selling 1 lot of TNOTE at 126.91, the margin will be: (1 (lot) x 1000 (contract size) x 126.91 (asset price)) x 1% (margin) = 1269.10 USD.
