Leverage Explained: Why High Leverage Offers Can Be Risky

✓ Last verified 2026-07-26

Leverage is the single feature most heavily marketed to new traders, and the one most responsible for wiping out accounts. Understanding the mechanics — not just the marketing pitch — matters before you touch the setting.

What leverage actually is

Leverage lets you open a position larger than your account balance by borrowing the difference from the broker, expressed as a ratio like 1:100 or 1:500. With $1,000 of capital and 1:100 leverage, you can control a $100,000 position. The broker requires you to set aside a portion of that as margin — the collateral for the borrowed amount.

Why higher leverage isn’t automatically better

The marketing framing is usually “more leverage means more profit potential” — which is true, but it’s only half the picture. Leverage scales your position size relative to a fixed deposit, which means it scales your losses by exactly the same factor as your gains. A 1% adverse move against a 1:100 leveraged position wipes out 100% of the margin backing that position. The same 1% move on an unleveraged position is a 1% loss. Leverage doesn’t change the market’s volatility — it changes how much of your account is exposed to that volatility.

How leverage interacts with margin calls and stop-outs

• Margin call — a warning that your account equity has fallen close to the minimum required to keep your open positions, typically triggered at a broker-defined percentage.
• Stop-out — the broker automatically closes some or all of your positions once equity falls below a lower threshold, to prevent your account from going negative (in jurisdictions/brokers without negative balance protection, this is also the mechanism that limits — but doesn’t always fully prevent — losing more than you deposited).
• The higher your leverage, the closer a stop-out sits to your entry price, meaning ordinary market volatility can trigger it faster than traders expect.

Reading a broker’s advertised leverage claims critically

• Very high leverage ratios (1:500, 1:1000, or higher) advertised prominently are often aimed at inexperienced traders rather than professionals — professional and institutional traders frequently use less leverage than what’s marketed to retail accounts.
• Some regulators cap the maximum leverage offered to retail clients specifically because of this risk profile (regulatory maximums vary significantly by jurisdiction and by regulator — check the specific rules that apply to the entity you’re trading with).
• A broker offering unusually high leverage compared to regulated competitors isn’t necessarily a red flag on its own, but combined with other warning signs (see our common forex scams guide) it’s worth extra scrutiny.

The practical takeaway

• Higher leverage means a smaller adverse price move can trigger a margin call or stop-out — it does not make trading inherently more profitable.
• Position size your trades based on how much of your account you’re willing to risk per trade, not based on the maximum leverage a broker offers.
• Understand your broker’s specific margin call and stop-out levels before you trade with meaningful leverage, and check whether negative balance protection applies to your account.
