Margin account[ edit ] A margin account is a loan account with a broker which can be used for share trading. The funds available under the margin loan are determined by the broker based on the securities owned and provided by the trader, which act as collateral for the loan.

Margin buying refers to the buying of securities with cash borrowed from a brokerusing the bought securities as collateral. This has the effect of magnifying any profit or loss made on the securities. The securities serve as collateral for the loan.
The net value—the difference between the value of the securities and the loan—is initially equal to the amount of one's own cash used.

Types of margin requirements[ edit ] The current liquidating margin is the value of a security's position if the position were liquidated now.
In other words, if the holder has a short positionthis is the money needed to buy back; if they are longit is the money they can raise by selling it.
The variation margin or mark to market is not collateral, but a daily payment of profits and losses. Futures are marked-to-market every day, so the current price is compared to the previous day's price.
The profit or loss on Margines na opcje sprzedawane na wymiane day of a position is then paid to or debited from the holder by the futures exchange.
This is possible, because the exchange is the central counterparty to all contracts, and the number of long contracts equals the number of short contracts.
Certain other exchange traded derivatives, such as options on futures contracts, are marked-to-market in the same way. The seller of an option has the obligation to deliver the underlying security associated with the option when it is exercised. To ensure they can fulfill this obligation, they have to deposit collateral. This premium margin is equal to the premium that they would need to pay to buy back the option and close out their position.

Initial and maintenance margin requirements[ edit ] The initial margin requirement is the amount of collateral required to open a position. Thereafter, the collateral required until the position is closed is the maintenance requirement.
The maintenance requirement is the minimum amount of collateral required to keep the position open and is generally lower than the initial requirement. This allows the price to move against the margin without forcing a margin call immediately after the initial transaction. When the total value of the collateral dips below the maintenance margin requirement, the position holder must pledge additional collateral to bring their total balance back up to or above the initial margin requirement.
On instruments determined to be especially risky, however, either regulators, the exchange, or the broker may set the maintenance requirement higher than normal or equal to the initial requirement to reduce their exposure to the risk accepted by the trader.
