Position Size Calculator

Proper risk management is the cornerstone of successful trading. A Position Size Calculator allows traders to determine the exact number of units, lots, or contracts to trade based on their defined risk tolerance. Whether you are trading Forex, Indices, or Cryptocurrency, computing your position size correctly ensures that a single losing trade will not heavily impact your overall account balance.

Simply enter your account balance, choose whether you want to risk a fixed amount or a percentage of your equity, and input your stop-loss distance. The calculator will automatically adjust for pip values across all major instruments to provide you with the optimal lot size.

Scenario: You have a $10,000 account, want to risk 1% per trade, and your stop loss on EUR/USD is 50 pips.

Step 1: Enter your account balance: $10,000

Step 2: Set risk to 1% (this means you are willing to lose $100 on this trade)

Step 3: Select EUR/USD as your pair

Step 4: Enter 50 pips as your stop loss distance

Result: The calculator shows 0.20 standard lots. This means each pip is worth $2, and 50 pips x $2 = $100, which is exactly 1% of your account.

Why this matters: If you traded 1.00 lot instead, your pip value would be $10, and a 50-pip stop loss would cost you $500 (5% of your account). One bad trade at that size puts you in a deep hole. The calculator prevents this.
