Leverage lets a trader control a position far larger than the cash in the account. A 30:1 ratio turns 1,000 units of deposit into 30,000 units of exposure. The pitch stops there. The arithmetic does not.
The multiplier runs both ways
The same factor that scales a favourable move scales an unfavourable one. On 30:1 exposure, a 1% move against the position erases roughly 30% of the margin behind it. A 3 to 4% move against a fully committed account can trigger a margin call and a forced close, often at the worst possible moment.
What the marketing omits
- Spreads and swaps are charged on the leveraged size, not the deposit, so holding costs are larger than they look.
- A stop-loss is not a guarantee. In a fast or gapping market the fill can be worse than the stop level.
- Negative-balance protection varies by jurisdiction and provider, and where it is absent, a loss can exceed the amount deposited.
The practical reading
Treat the advertised ratio as a description of risk, not of opportunity. Size positions from the loss you can absorb, confirm whether negative-balance protection applies to your account, and read the provider's margin-close policy before it reads you.
