Forex pairs trade in 1000, 10,000 and 100,000 units, called micro, mini and standard lots. When starting out in forex day trading it's recommended traders open a micro lot account. Trading micro lots allow for more flexibility so risk remains below 1% of the account on each trade. When the USD is listed second in the pair, as in the EUR/USD or AUD/USD, the value of the pip is fixed. If you hold a 1000 micro lot, each pip movement is worth $0.10. If you hold a 10,000 mini lot then each pip is worth $1.
