The gross profit on your trade is calculated as follows:

Opening the Position

The price of the VIX is 14.05/14.20. You are of the view that market volatility will increase so you decide to buy 1 contract at 14.20. (One contract is equal to $500 per point, there are 100 points per 1.00 change in the index). No commission is charged on Futures CFDs.

For every point that the bid quote on the VIX rises above 14.20 you will make a profit of $500 USD; for every point the bid quote falls below 14.20 you will lose $500 USD.

Closing the Position

Four days later, the VIX has risen to 15.20/15.35 and you decide to take your profit. You close your position by selling 1 contract at 15.20.
