Leverage lets you control a large position with a small deposit. At 1:100, $100 of margin controls a $10,000 position. Brokers advertise it as a gift; statistically, it is the single fastest way beginners destroy accounts. Both things are true — the difference is understanding what leverage actually changes.
Leverage amplifies exposure, not edge
Your win rate doesn't improve because you borrowed size. A 1% move for you is still a 1% market move — leverage just multiplies its effect on your balance. At 1:100 fully deployed, a 1% adverse move erases the entire margin. That is not trading; it is a coin flip with fees.
The professional reframe
Skilled traders don't think "how much CAN I control?" but "what size keeps my loss at 1% if my stop is hit?" Leverage then becomes plumbing — a facility that lets a small account express a properly-sized position — rather than a throttle held wide open. Used this way, high account leverage with tiny actual exposure is perfectly safe.
Margin calls, demystified
Margin is the collateral locked for a position. If floating losses eat your free margin, the broker closes positions automatically — the margin call. Traders who size from stop distance and risk percentage essentially never meet one; traders who size from greed meet them monthly.
A sane starting point
Keep effective risk at 1% per trade regardless of the leverage available. Read Position Sizing to see the exact formula — it makes leverage almost irrelevant, which is precisely the point.
Education only — not financial advice. Trading carries risk of loss; never trade money you cannot afford to lose.
