Margin — Frequently Asked Questions
Each question is answered directly below. Expand any item for the full response.
What is trading margin?
Margin is the capital you must provide to control a larger position through leverage. It increases buying power, but it also magnifies losses and can trigger forced action if the position moves against you.
How does leverage affect margin required?
Higher leverage lowers the upfront margin required for the same position value because you are borrowing more exposure per unit of capital. The danger is that a small adverse move then causes a larger percentage loss on your actual money.
Why is low margin requirement not the same as low risk?
Because the market risk comes from the full position size, not only from the initial capital posted. A cheap-looking entry can still be extremely risky if leverage is high.
What should traders check besides margin required?
Check maintenance rules, peak-margin requirements, overnight policy, and what happens if the broker squares off positions. A trade can be right on direction and still fail if the account cannot support the margin path.
