Trading with CFD (Contract for Difference) allows traders to speculate with an instrument's price variation over time. In this case, there are two directions that an instrument's price can go - it can either fall or rise. When we speculate that the price of a given instrument will fall, we can open a short position. Whenever we speculate the price will rise, we can open a long position.
Whenever you are placing a short or long position, you should make sure you are referring to the related price chart of the position.
1. Short Position
We can open a short position by "Sell" -ing units at the current price of an instrument.
Respectively, we can open a long position by "Buy" -ing units of a given instrument.
