What Is Leverage in Trading, and Why Does It Cut Both Ways?

Leverage, defined simply

Leverage lets you control a position larger than your own deposit. With 1:500 leverage, $1 of your own capital can control a $500 position. It does not give you extra money — it lets your existing capital open bigger positions, which means both gains and losses are calculated on that larger position size, not just your original deposit.

The amplification, with real numbers

Say you open a $10,000 position (using leverage) with $100 of your own capital — that is 100:1 exposure relative to your deposit. If the position moves 1% in your favor, you gain $100 — doubling your capital. If it moves 1% against you, you lose $100 — your entire deposit, wiped out by a genuinely small 1% market move. That asymmetry is the entire reason leverage is dangerous: small, completely normal market movements become account-ending events when leverage is misused.

Why leverage exists at all

It lets traders with smaller accounts participate meaningfully in markets that would otherwise require far more capital, and it is standard across the industry — TAG Markets, like most forex/CFD brokers, offers leverage up to 1:500 on MetaTrader 5. High available leverage is not itself a red flag; how it gets used is what determines the outcome.

How to actually use leverage without blowing up an account

• Just because 1:500 is available does not mean using the maximum is sensible — position size relative to your account matters far more than the leverage ratio itself.
• Risk a small, fixed percentage of your account per trade, regardless of how much leverage is technically available.
• Always know your maximum possible loss on a position before you open it, not after.
