Margin trading lets traders borrow funds from an exchange to start trading in an amount larger than their capital. The trader only needs to provide a fraction of the total trade value, known as the margin or collateral, to initiate the process.
For instance, with 10x leverage and a $500 deposit, a trader can have a $5,000 position. Profits scale up if the price moves in the right direction. Losses will occur if it does not.
Most major centralized exchanges like Binance, Bybit, Kraken, and OKX offer margin accounts. Setup involves a standard exchange account, identity verification (KYC), and switching on the margin section from the dashboard. Access to margin accounts is not allowed in every country due to local regulations and restrictions.
Once approved, the collateral goes into the margin wallet, a leverage ratio is chosen by the trader, and a position is opened. The exchange lends the remaining funds and charges interest for as long as the trader holds the position open.

Two modes are common across platforms. Isolated margin limits exposure strictly to the funds tied to that one trade. Cross-margin pulls from the full account balance to hold a position open, and one poorly managed trade can drag down everything sitting in the account.
Cross a certain loss threshold, and the exchange closes the position without warning. That is liquidation — collateral gone, no appeal, no reversal. A stop-loss is the simplest defense against it, cutting the trade at a set point before damage compounds.
