How is margin calculated?
Required margin = (lots x contract size x price) / leverage. A 1-lot EURUSD position at 1.10 with 1:100 leverage needs about (1 x 100,000 x 1.10) / 100 = $1,100.
What leverage should I use?
Lower is safer. High leverage magnifies both gains and losses; many professionals keep effective leverage low regardless of what the broker offers.
What is a margin call?
When your equity falls below the margin required to hold open positions, the broker may close trades automatically. Conservative position sizing avoids this.
