How do traders use credit in day trading?

• A. To increase purchasing power, allowing them to buy more securities than cash alone
• B. To avoid all fees and commissions
• C. To guarantee profits regardless of market moves
• D. To reduce the risk of loss by hedging fully

Answer: (A)

Traders use credit in day trading by leveraging their buying power through a margin account, borrowing funds from the broker to control more shares or contracts than their cash would permit. This borrowed capital can amplify both gains and losses, so even small market moves can have larger percentage impacts when positions are bigger. But it comes with costs and risks: interest on the borrowed funds, maintenance margin requirements, and the possibility of a margin call or forced liquidation if the account balance falls too far. The goal is to increase potential upside, not to guarantee profits or avoid costs, and it doesn’t provide a full hedge against risk. So the idea is that credit increases purchasing power, allowing you to buy more securities than cash alone.
