How to Calculate Margin in Forex
What is Margin in Forex?
Margin is not a cost or fee; it is a security deposit held by your broker to cover potential losses. It allows you to control larger positions with a smaller amount of capital. For example, with 1:100 leverage, you can control $100,000 with only $1,000 margin.
Margin Formula
The basic formula is: Margin = (Trade Size / Leverage) x Exchange Rate. Trade size is measured in lots (1 standard lot = 100,000 units of base currency). Leverage is the ratio provided by your broker. Exchange rate converts the base currency to your account currency (USD).
Example Calculation for Tajikistan
Suppose you trade 0.1 lot (10,000 units) of GBP/USD with 1:50 leverage. Current GBP/USD rate is 1.25. Margin = (10,000 / 50) x 1.25 = 250 USD. This means you need $250 in your account to open this trade.
Required vs Used Margin
Required margin is the amount needed to open a new position. Used margin is the total margin locked by all open positions. Free margin is your account equity minus used margin. Always keep free margin positive to avoid margin calls.
Margin Level and Stop-Out
Margin level = (Equity / Used Margin) x 100%. If margin level falls below the broker's stop-out level (e.g., 50%), your broker will automatically close positions. For Tajikistan traders, this is crucial because local brokers may have different stop-out thresholds.
