Leverage is the most misunderstood number in a forex account. Most people think higher leverage means bigger risk. It doesn't, directly. Leverage decides how much margin a position needs. Your lot size decides your risk. The two are connected, but confusing them is how accounts get blown.
What leverage means
Leverage lets you control a position larger than the money in your account. At 1:100, every $1 of margin controls $100 of position.
One standard lot of EURUSD is 100,000 euros, about $108,500 at 1.0850. The margin needed to open it:
| Leverage | Margin for 1 lot EURUSD | Margin for 0.10 lots |
|---|---|---|
| 1:30 | $3,617 | $362 |
| 1:100 | $1,085 | $109 |
| 1:500 | $217 | $22 |
Margin = contract size × lots × price ÷ leverage
The formula is the same on every MT5 FX pair, with the price converted into your account currency. For metals, indices and CFDs, the broker sets the margin rate per symbol; it's in the symbol specification.
Leverage doesn't change your pip value
Here's the part that matters. One lot of EURUSD moves about $10 per pip whether your leverage is 1:30 or 1:500. Leverage changed how much margin was locked up. It didn't change how much you make or lose per pip.
So two traders, each with $10,000 and each buying 1 lot of EURUSD, take identical risk: a 50-pip move costs both $500. The only difference is that the 1:30 trader has $3,617 of margin in use and the 1:500 trader $217.
That difference shows up in free margin, the money available before the broker starts closing positions. More leverage means more free margin, which means:
- You can open bigger positions than your account can survive. That's the danger: not leverage itself, but the size it lets you reach.
- A losing position takes longer to hit a margin call. That's the benefit: a sensibly sized trade isn't stopped out by margin before its own stop loss.
The margin level post covers free margin, margin level and stop-out in detail.
Effective leverage: the number that actually measures risk
The leverage your broker gives you is a maximum. What you're actually using is effective leverage:
Effective leverage = total open position value ÷ account equity
A $10,000 account with 1 lot of EURUSD open ($108,500) is running about 11:1 effective leverage, whether the account is set to 1:30 or 1:500.
Effective leverage tells you how far price can move against you before the account is wiped out. At 11:1, a 9% move against you loses everything. At 50:1, a 2% move does, and 2% moves happen in EURUSD over a few weeks, and in gold in an afternoon.
Most professional risk guidelines keep effective leverage low, often well under 10:1, and size each trade from its stop loss rather than from available margin. The lot size post has the sizing formula.
Regulatory leverage limits
Retail leverage is capped in many jurisdictions. The EU (ESMA) and UK (FCA) limits are typical, and Australia (ASIC) adopted the same levels:
| Instrument | Maximum retail leverage |
|---|---|
| Major FX pairs | 30:1 |
| Non-major FX pairs, gold, major indices | 20:1 |
| Other commodities, non-major indices | 10:1 |
| Individual equities | 5:1 |
| Cryptocurrencies | 2:1 |
In the US, the limit is 50:1 on major pairs and 20:1 on others. Brokers in other jurisdictions often offer 1:500 or more. Professional clients can qualify for higher limits, but lose some retail protections.
These caps exist for the reason in the previous section: high available leverage makes it easy to open positions far larger than the account can absorb.
Leverage on prop firm accounts
Prop firm challenges usually set leverage per instrument, often 1:100 on FX and lower on indices and metals. It matters less than it seems, because the firm's daily and maximum loss limits constrain your size far more tightly than margin does. A 5% daily loss limit is effectively a cap on how much you can risk at once; the prop firm drawdown post shows how those limits are measured.
What leverage should a beginner use?
The question is really "how big should my positions be?", and the answer comes from risk, not leverage:
- Decide your risk per trade, typically 0.5–2% of equity.
- Set the stop loss where the trade idea is wrong.
- Calculate the lot size that loses exactly that amount at the stop.
- Check the margin, and leave plenty of free margin so the broker never closes you before your own stop does.
With that process, account leverage only needs to be high enough that sensibly sized trades don't run short of margin. 1:30 to 1:100 is plenty for most FX traders. Very high leverage adds no profit to a well-sized trade; it only removes a safety margin against a badly sized one.
Watching margin automatically
If you run EAs or trade several accounts, margin can tighten while you're not
looking. With an account on MetaKit, an equity monitor
on the margin_level metric alerts you on Telegram, Slack, Discord or a
webhook when margin level falls below a threshold you set, well before the
broker's margin call.
