How to calculate Profit / Loss

How is Floating P/L (Profit/Loss) calculated in the Trade/Zero (CFD) trading accounts? 

To calculate the P&L of a position, what you need is the position size and the number of pips the price has moved. The actual profit or loss will be equal to the position size multiplied by the pip movement or you can also use 2 quite straightforward formulas depending on the direction of your position: 

P&L (Long) = (Close price - Open Price) *Lots*Lot Size 

P&L (Short) = (Open Price -Close price) *Lots*Lot Size, 

Where Lots - the amount of open lots; 

Lot size - a quantity of the underlying asset units in a single standardized contract, can be found on the Contract specification page.
