Forex is one of the most leveraged markets available to individual traders. A broker might let you control a $100,000 position with $2,000 of margin, leverage of 50 to 1. Leverage magnifies gains and losses equally, which is why many retail forex accounts lose money. Understanding how margin is calculated, what limits regulators set and what happens when your account runs low is essential before trading. The general concepts are in [Leverage](https://learn.tradelabsai.com/markets/leverage/) and [Margin](https://learn.tradelabsai.com/markets/margin/).

## Leverage and margin

```
required margin = notional value / leverage
leverage = notional value / margin
```

| Leverage | Margin as % of position | Margin for $100,000 position |
|---|---|---|
| 10:1 | 10% | $10,000 |
| 30:1 | 3.33% | $3,333 |
| 50:1 | 2% | $2,000 |
| 100:1 | 1% | $1,000 |
| 500:1 | 0.2% | $200 |

## Regulatory limits

| Jurisdiction | Typical maximum leverage for retail clients |
|---|---|
| United States (CFTC and NFA) | 50:1 on major pairs, 20:1 on others |
| European Union (ESMA) and UK (FCA) | 30:1 on major pairs, 20:1 on minors, gold and major indices, lower on others |
| Australia (ASIC) | 30:1 on major pairs |
| Some offshore brokers | 500:1 or more |

ESMA introduced its limits in 2018, along with negative balance protection for retail clients, after finding most retail CFD and forex accounts lost money. Many brokers in these regions must disclose the percentage of retail accounts that lose money, often between about 60% and 80%. Very high leverage offered offshore comes with less regulatory protection. See [Trading Regulators: SEC, CFTC, FINRA and NFA](https://learn.tradelabsai.com/industry/trading-regulators/).

## Account terms

| Term | Meaning |
|---|---|
| Balance | Cash in the account, excluding open trade profit or loss |
| Equity | Balance plus or minus open profit or loss |
| Used margin | Margin locked by open positions |
| Free margin | Equity minus used margin, available for new trades |
| Margin level | Equity / used margin × 100% |
| Margin call level | Margin level at which the broker warns you (often 100%) |
| Stop out level | Margin level at which the broker closes positions (often 50% or lower) |

## How a stop out happens

**Example: Running out of margin**
You deposit $2,000 and buy 1 standard lot of EUR/USD at 1.0850 with 50:1 leverage. Used margin is about $2,170, which already exceeds your $2,000, so the broker would reject the trade. Suppose instead you buy 0.5 lots (€50,000). Used margin is about $1,085 and equity is $2,000, a margin level of 184%.

EUR/USD falls 100 pips to 1.0750. Loss: 100 × $5 = $500. Equity: $1,500. Margin level: 138%.
It falls another 100 pips to 1.0650. Equity: $1,000. Margin level: 92%, below the margin call level.
At a 50% stop out level, the broker closes the position when equity falls to about $543, which happens around 1.0558, a fall of about 292 pips from entry. You would have lost about $1,457, roughly 73% of your deposit, on a 2.7% move in EUR/USD.

## Effective leverage

What matters is not the maximum leverage your broker allows but the leverage you actually use:

```
effective leverage = total notional of open positions / account equity
```

A $10,000 account holding $50,000 of positions has effective leverage of 5:1, regardless of whether the broker offers 30:1 or 500:1. Many professional traders keep effective leverage low.

## Using leverage safely

1. **Size by risk per trade,** not by available margin. See [Position Sizing](https://learn.tradelabsai.com/risk/position-sizing/).
2. **Keep effective leverage modest,** especially across correlated pairs. See [Currency Correlations](https://learn.tradelabsai.com/forex/currency-correlations/).
3. **Always use stop losses,** knowing they can slip in fast markets.
4. **Watch for weekend gaps** and major news events.
5. **Prefer brokers with negative balance protection** and strong regulation.

## Extreme events

On 15 January 2015, the Swiss National Bank abandoned its cap on the franc. EUR/CHF fell about 30% within minutes, with almost no prices in between. Stops filled far from their levels, many retail accounts went negative, and several brokers suffered large losses or failed.
