Broker advertising loves the word "leverage": invest a hundred dollars — trade ten thousand. Sounds like a gift, but regulators worldwide agree: margin trading is the main reason 70–80% of retail traders lose money. Let's understand how this tool works and where the catch is.

What is leverage

Leverage is a loan from your broker secured by your funds. The notation "1:10" means: for every unit of your money, the broker adds nine of theirs. With a $1,000 deposit, you open a $10,000 position.

Your money becomes margin — the loan collateral. Profit and loss are calculated from the full position volume but affect your margin entirely.

Math cuts both ways

A $10,000 position with 1:10 leverage, your margin is $1,000.

  • Price rises 2% → profit $200 → +20% to deposit.
  • Price falls 2% → loss $200 → −20% of deposit.
  • Price falls 10% → loss $1,000 → deposit wiped out.

A normal daily fluctuation you wouldn't notice without leverage becomes a fifth of your account lost with 1:10 leverage, or account wipeout from a 1% move with 1:100 leverage.

Margin call and liquidation

Your broker won't lose their money. When losses consume your margin to a critical level, a margin call arrives — a demand to top up your account. If you don't, the position closes forcibly, locking in the loss. During sharp moves, liquidation happens instantly without warning — price simply doesn't allow time.

Hidden costs

  • Position rollover fee — the loan isn't free: a percentage accrues for each day you hold it.
  • Spread widening — during volatility, the bid-ask spread grows, and stops trigger sooner than planned.
  • Gaps — price can jump past your stop, and losses exceed what you calculated.

Does leverage have a legitimate place

Yes — in the hands of an experienced trader with strict risk management. Professionals use leverage not to increase risk, but for capital efficiency: their risk per trade remains 1–2% of deposit, just a smaller sum provides the needed volume. The difference is crucial: leverage scales position size, not risk.

Safety rules

  1. Trade without leverage entirely for the first year.
  2. Once comfortable, don't exceed 1:2–1:5 — this suffices for nearly any goal.
  3. Calculate risk from full position size, not margin.
  4. Never hold a margin position through losses — time works against you due to rollover fees.
  5. Remember: leverage offers of 1:100 and higher signal a "bucket shop" profiting from your losses, not an honest intermediary.

Those not yet ready for such risks are better off growing capital conservatively — for example, through bank deposits — and entering the market only with money you can afford to lose consciously.

Conclusion: leverage is an amplifier. It doesn't make a strategy profitable, only multiplies what exists: efficiency for disciplined traders, speed of account depletion for beginners.
