Pips, Lots and Position Sizing Explained
Master the building blocks of forex position management — what a pip is worth, the difference between lot sizes, and how to calculate your exposure.
- 1A pip is the smallest standard price movement — usually the 4th decimal place.
- 2A standard lot is 100,000 units; a mini lot is 10,000 units; a micro lot is 1,000 units.
- 3Your pip value depends on the pair traded, lot size, and your account currency.
- 4Proper position sizing is the foundation of good risk management.
Two terms you'll see constantly in forex trading are pips and lots. Understanding both is essential before you place your first live trade.
What is a Pip?
A pip (percentage in point) is the smallest standard price increment in forex. For most currency pairs, a pip is the movement in the 4th decimal place:
EUR/USD moves from 1.0850 to 1.0851 → that's a 1 pip move
GBP/USD moves from 1.2700 to 1.2710 → that's a 10 pip move
For JPY pairs (USD/JPY, EUR/JPY etc.), a pip is the 2nd decimal place because Yen has a much lower unit value. USD/JPY moving from 151.20 to 151.21 is a 1 pip move.
Many brokers also quote a 5th decimal place (called a pipette or fractional pip) for more precise pricing.
What is a Lot?
Forex is traded in standardised amounts called lots:
The lot size you trade directly determines how much each pip movement is worth to you.
| Lot Type | Units of Base Currency |
|---|---|
| Standard | 100,000 |
| Mini | 10,000 |
| Micro | 1,000 |
| Nano | 100 |
Calculating Pip Value
For USD-quoted pairs (EUR/USD, GBP/USD):
Pip Value = (0.0001 / Exchange Rate) × Lot Size
For a standard lot of EUR/USD at 1.0850:
Pip Value = (0.0001 / 1.0850) × 100,000 = $9.22 per pip
For a micro lot of EUR/USD:
Pip Value = (0.0001 / 1.0850) × 1,000 = $0.09 per pip
This is why beginners should start with micro or mini lots — a 50 pip loss on a micro lot is only $4.50, whereas the same move on a standard lot is $461.
