Trading on margin means that an investor can buy and sell assets that represent more value than the capital in their account. Forex trading is typically executed on margin, and the industry practice is to trade on relatively small margin amounts since currency exchange rate fluctuations tend to be less than one or two percent on any given day.

Margin, or leverage, implies that the investor is "gearing" his or her funds. Margin rates of 1% on the $10,000 in are common in online trading. What this means is that a margin of 1.0% enables one to trade up to $1,000,000 even though there is $10,000 in the account. In terms of leverage this corresponds to 100:1. STIFX provides the same leverage, as well can offer 200:1.

Using leverage opens the possibility to generate profits quickly, but increases the risk of rapidly incurring losses. It is important to review the margin thresholds and limitations in your trading agreement to determine the range of trading activities you can undertake.

Net equity for Margin is the absolute indicator of the extent of margin capability in your account. If your Margin Required exceeds your Net Equity for Margin you must close or reduce positions, or send additional funds to cover your positions.

You can trade on unrealized profits in your account. Margin calculations are based on the Net Equity for Margin which includes such unrealized profits and losses as are current in your account.

Traders must maintain the margins listed in their account at all times. If funds in an account fall below the margin requirement, a margin call is issued. A margin call requires the trader to immediately deposit more funds to cover the position or to close the position.

The amount of the trade size is limited by the margin position. For example, a trader with $10,000 in funds and 1% margin, can trade as much as $1,000,000.
