Margin is the minimum amount of equity a trader must maintain in their margin account. This percentage is set by the brokerage and can vary by asset type and market conditions. It is not a transaction cost, but rather a security deposit that the broker holds while your trade is open. Margin trading offers greater profit potential than traditional trading, but also greater risks.
Margin by the arrow is automatically calculated and assigned, or added, to the margin section on your trading terminal. Once you execute a trade order, look out for its corresponding margin in the section as indicated in the picture below.

Practical Example
If you want to buy $10,000 worth of a stock with a 50% initial margin requirement:
1. Your Contribution: $5,000 (The Margin).
2. Broker’s Loan: $5,000.
3. Outcome A (10% Gain): Asset becomes worth $11,000. You pay back the $5,000 loan. Your $5,000 has turned into $6,000 (20% return).
4. Outcome B (10% Loss): Asset becomes worth $9,000. You still owe $5,000. Your equity is now $4,000 (20% loss).
Margin trading is a powerful tool in the global financial markets that allows traders to amplify their investment capacity through borrowed funds. However, it carries substantial risks, requiring a solid understanding of leverage, margin requirements, and market dynamics. Investors should carefully evaluate their risk tolerance and financial situation before engaging in margin trading.
