How to properly size your trading position?

The risk per trade rule

Most professional traders never risk more than 1% to 2% of their capital per trade. On a $1,000 account, this means a maximum risk of $10 to $20 per position. This money management discipline protects your capital against the inevitable losing streaks in trading.

The risk/reward ratio

A good risk/reward ratio is at least 1:2 — your potential gain should be at least double your risk. With a 1:2 ratio, you can be profitable even winning only 40% of your trades. The higher the ratio, the more robust your strategy in the long run.

Forex position size

In Forex, size is measured in lots. A standard lot is worth 100,000 units of the base currency. A mini-lot (0.10) is worth 10,000 units and a micro-lot (0.01) is worth 1,000 units. The pip value varies by pair: approximately $10 per pip for a standard lot on EUR/USD.

Gold and crypto specifics

Gold (XAU/USD) is traded with a standard contract of 100 ounces. Its high volatility requires careful sizing. Cryptocurrencies are traded in units (BTC, ETH...) and their extreme volatility makes risk management even more critical — adjust your position size accordingly.

Frequently asked questions

What is a lot in forex?+
A lot is the standard unit of trading volume on the forex market. A standard lot equals 100,000 units of the base currency. There are also mini lots (10,000), micro lots (1,000) and nano lots (100). The lot size determines the monetary value of one pip.
How to calculate the ideal lot size?+
The ideal lot size depends on 3 factors: your account capital, the risk percentage you accept per trade (generally 1-2%), and the distance to your stop loss in pips. Our calculator automates this: it tells you how many lots to trade to never lose more than your defined risk.
What is the 1% rule in trading?+
The 1% rule means risking a maximum of 1% of your capital on any single trade. On a $10,000 account, you accept losing $100 if the trade fails. This rule protects you from capital erosion after a bad streak: even 10 losses in a row cost only 10%.
How much does 1 pip earn on EUR/USD?+
On EUR/USD, a standard lot (100,000 €) represents $10 per pip. A mini lot earns $1 per pip, a micro lot $0.10 per pip. Multiply by the number of pips gained or lost to get the P&L in USD. Our calculator gives you this value in real time for any pair.
Why calculate position size before entering?+
Entering a position without calculating the size exposes you to disproportionate losses. 85% of retail forex traders lose money, largely due to poor position sizing. Calculating the lot before entry is the #1 difference between professional traders and beginners.
