What is Lot Size in Forex? Why Does it Matter?
Lot size in Forex is the available trade size in the Forex market. There are mainly 3 types of lot sizes, each suited to a different account size and experience level.
| Lot Size | Trade Volume | Best for |
|---|---|---|
| Standard (1.0) | 100,000 units | Larger accounts or experienced traders |
| Mini (0.1) | 10,000 units | Intermediate traders |
| Micro (0.01) | 1,000 units | Beginners or small accounts |
For example:
- On a standard lot, 1 pip move = $10
- On a micro lot, 1 pip move = $0.10
If you place a forex trade with a 15 pip stop-loss, you're risking $150 on a standard lot or just $1.50 on a micro lot. Getting the wrong lot size is the fastest way to overtrade and wipe your account.
