How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a fee or a cost; it is a deposit held by your broker to ensure you can cover potential losses. In Ecuador, margin is expressed in USD. For example, if you want to trade 1 standard lot of EUR/USD with 1:100 leverage, your margin requirement is 1,100 USD.
The Margin Formula
The formula to calculate margin is: Required Margin = (Lot Size × Contract Size × Current Price) / Leverage. For Ecuador traders, the contract size is always 100,000 units for a standard lot, 10,000 for a mini lot, and 1,000 for a micro lot. Since your account is in USD, the price of the currency pair is the current market rate.
Example 1: Standard Lot EUR/USD
Let's say you want to buy 1 standard lot of EUR/USD at a price of 1.1000 with 1:100 leverage. The calculation is: (1 × 100,000 × 1.1000) / 100 = 1,100 USD. This means you need 1,100 USD in your account to open this trade. If you have a 500 USD account, you cannot open this position.
Example 2: Mini Lot USD/JPY
For a mini lot (10,000 units) of USD/JPY at 110.00 with 1:200 leverage: (1 × 10,000 × 110.00) / 200 = 5,500 JPY, but since your account is in USD, divide by 110.00 to get 50 USD. So margin required is 50 USD.
Margin Level and Margin Call
Margin Level = (Equity / Used Margin) × 100%. If your margin level falls below the broker's threshold (e.g., 100%), you get a margin call. In Ecuador, many brokers set the stop-out level at 50%, meaning your positions close automatically if margin level hits 50%. Always keep your margin level above 200% to be safe.
