The trader, after an extensive analysis, decides there is a higher probability of the British pound to go up. He or she decides to go long risking 30 pips and having a target (reward) of 60 pips. If the market goes against our trader he/she will lose 30 pips, on the other hand, if the market goes in the intended way, he or she will gain 60 pips. The actual quote for the pound is 1.8524/27, 4 pips spread. Our trader gets long at 1.8530 (ask). By the time the market gets to either our target (called take profit order) or our risk point (called stop loss level) we will have to sell it at the bid price (the price our broker is willing to buy our position back.) In order to make 40 pips, our take profit level should be placed at 1.8590 (bid price.) If our target gets hit, the market ran 64 pip fiat currency s (60 pips plus the 4 pip spread.) If our stop loss level is hit, the market ran 30 pips against us.It’s very important to understand every aspect of trading.
