What margin means
Margin is the capital your broker sets aside to open and maintain a leveraged position. It is not the full trade size, but it directly affects how much exposure your account can support.
Worked Example
One standard lot of EUR/USD at 1.0900 has a notional value of about $109,000. At 1:100 leverage, the required margin is roughly $1,090.
Choose an instrument, lot size, and leverage to estimate the required margin.
