A lot is the standard unit of measurement for trade size in forex. A standard lot equals 100,000 units of the base currency. A mini lot equals 10,000 units (0.10 lots). A micro lot equals 1,000 units (0.01 lots). The lot size you choose directly determines how much money you gain or lose per PIP. Larger lot sizes mean larger profits and larger losses. Always calculate the correct lot size based on your account balance and risk tolerance before entering any trade.

Common questions about lot sizes and position sizing in forex.
Most professional traders recommend risking between 1% and 2% of your account balance per trade. This means if you have a $10,000 account, you should risk no more than $100–$200 on any single trade. Risking more than 5% per trade is considered high risk and can lead to rapid account drawdown after a losing streak. Consistent small risk per trade is the foundation of long-term profitable trading.
Your stop-loss distance directly determines your lot size. The wider your stop-loss (more PIPS), the smaller your lot size must be to keep the same risk amount. The tighter your stop-loss (fewer PIPS), the larger your lot size can be. For example, with a $200 risk on EUR/USD — a 20 PIP stop allows a 1.00 lot, but a 100 PIP stop only allows a 0.20 lot. This is why proper stop-loss placement is critical before calculating position size.
Percentage risk means you risk a set percentage of your current account balance on each trade (e.g. 2%). As your balance grows your risk amount grows too, and as it shrinks your risk reduces automatically — this protects your account during losing streaks. Fixed Amount means you always risk the same dollar amount per trade (e.g. $200) regardless of your balance. Percentage-based risk is generally recommended for consistent long-term account growth.
