How to Calculate Margin in Forex
What is Forex Margin?
Forex margin is not a fee or cost—it is a security deposit held by your broker to cover potential losses. In Timor-Leste, most brokers offer leverage, which means you control a large position with a small deposit. For example, with 1:100 leverage, a $1,000 margin controls $100,000. The margin is returned when you close the trade.
Margin Formula for Timor-Leste Traders
The standard margin formula is: Required Margin = (Trade Size / Leverage) x Exchange Rate. Trade size is measured in lots (1 standard lot = 100,000 units). Leverage is the ratio (e.g., 100:1). Exchange rate is the current price of the base currency in your account currency (USD for Timor-Leste).
Example 1: EUR/USD with 1:100 Leverage
You want to buy 1 standard lot of EUR/USD at 1.1000. Trade size = 100,000 EUR. Leverage = 100:1. Margin = (100,000 / 100) x 1.1000 = $1,100. So you need $1,100 in your account to open this trade.
Example 2: USD/JPY with 1:200 Leverage
You want to buy 1 mini lot (10,000 units) of USD/JPY at 110.00. Since USD is the base currency, margin = (10,000 / 200) x 1 = $50. No exchange rate conversion needed because your account is in USD.
Example 3: GBP/USD with 1:50 Leverage
You want to buy 0.5 lots (50,000 units) of GBP/USD at 1.3000. Margin = (50,000 / 50) x 1.3000 = $1,300. Higher leverage reduces margin but increases risk.
Margin Call and Stop Out Levels
Brokers set margin call levels (e.g., 100% margin used) and stop out levels (e.g., 50% margin used). In Timor-Leste, always monitor your margin level: (Equity / Used Margin) x 100%. If it falls below the stop out level, your positions will be closed automatically.
