Leverage and margin explained

Why 50:1 leverage can wipe you out faster than it can make you rich.

TL;DR

Leverage lets you control a large forex position with a small deposit. Margin is the deposit. The catch: leverage amplifies losses exactly as it amplifies gains — and FX losses can wipe an account fast.

The math

1:50 leverage means $1 of margin controls $50 of position size. For a $5,000 account at 1:50 leverage, you can open up to $250,000 in notional positions. Sounds great until you realise a 2% move against you wipes the entire account.

Margin types

Brokers track several margin numbers — knowing what they mean prevents margin calls.

→Required margin — what the broker locks up to open a position
→Used margin — total locked across all open positions
→Free margin — what's left for new positions or absorbing drawdown
→Margin level — equity ÷ used margin × 100%. Below 100% triggers margin calls; below 50% triggers liquidations on many brokers

Regulator-imposed limits

Leverage caps protect retail traders from blowing up too fast.

→EU/UK retail: 1:30 on majors, lower on minors and exotics
→US retail: 1:50 on majors, 1:20 on minors
→Australia/Japan: 1:30 typically
→Offshore brokers: often 1:500 or even 1:1000 — high risk of stop-outs

Worked example

What leverage does to a 1% move

$10,000 account, 1 standard lot ($100,000 notional) of EUR/USD.

1Effective leverage$100,000 ÷ $10,000 = 1:10
21% move on EUR/USD~100 pips
3Dollar P/L per pip~$10
4P/L on a 100-pip move$1,000 — 10% of account
5If you'd used 1:505 lots × $1,000 = $5,000 swing — 50% of account on a 1% move

Takeaway

Effective leverage — what you actually use — matters far more than what the broker offers. Most pros stay under 1:10 effective.

Common mistakes

What to avoid

!Confusing max leverage offered with effective leverage used
!Adding to losing positions to 'average down' — multiplies leverage when you can least afford it
!Trading near major news without widening stops — gaps can blow through liquidation levels
!Treating leverage as a way to make 'big' trades on small accounts — it's a way to lose them faster
