What is leverage and how not to blow up with it
Leverage is the ability to control a position bigger than the money you actually have: with 1:100 leverage, €100 lets you move €10,000 in the market. It's sold as trading's great advantage, but it's above all an amplifier: it multiplies your gains and losses exactly the same. It's not the enemy — misunderstood, it's the number-one reason small accounts die fast.
How it works: the broker lends you muscle
When you trade with leverage, the broker lets you open a position many times larger than your deposit. You only put up a fraction (the "margin") as collateral. If the market moves in your favour, you win as if you'd invested the whole position; if it moves against you, you lose just as fast. With 1:100, a move of barely 1% against you can wipe out your entire deposit. That number —1%— is what almost nobody calculates at the start, and what changes everything.
The fatal misunderstanding: confusing leverage with risk
Here's the key almost nobody explains well: the leverage your broker offers is not the risk you take. You can have an account with 1:500 leverage and risk only 1% per trade, if you size your position correctly. Leverage is just the tool that lets you open the position; the real risk is decided by you with size and the stop loss. Confusing the two —"I have a lot of leverage, so I risk a lot"— is the mental mistake that blows up accounts.
The professional rule (boring and life-saving)
| Amateur use | Professional use |
|---|---|
| "I use maximum leverage to win more" | The available leverage is irrelevant; what I set is the risk |
| Size decided by greed | Size decided by risk: 1-2% of the account per trade |
| A small move against = account wiped | Whatever the volatility: the maximum loss is fixed beforehand |
The rule is always the same: you first decide how many euros you're willing to lose (1-2% of the account), measure the distance to your stop, and the position size falls out of that. Leverage is just the mechanism that makes opening that size possible — not an invitation to use it to the max.
So, is it good or bad?
Leverage is neutral, like a powerful car: in the hands of someone who respects the rules it's a useful tool; in the hands of someone who confuses power with permission to speed, it's an accident waiting to happen. Used with risk management, it lets you trade reasonable sizes with little capital. Used without it, it's the fast lane to losing everything. The difference isn't in the leverage: it's in whether you control your risk. You have it laid out in the 1% rule, and the full market context in what is Forex.
