Leverage

Leverage is the ability to open a position larger than the money in your account. At 1:100, every dollar of margin lets you carry 100 dollars of position. You do not pay for the whole position; the broker sets aside a small part of its size from your account as margin.

Example: with EUR/USD at 1.0800, one standard lot is 100,000 euros, about 108,000 dollars. At 1:100 that ties up 1,080 dollars of margin. At 1:30 the same position needs 3,600 dollars. The position is identical, and so is the gain or loss per pip. Only the money set aside changes.

Leverage magnifies size, not skill. Someone who reads price well does not read it better with leverage. Someone who reads it badly makes the same mistake on a bigger position. What grows gains and losses together is the size of the position you open.

What matters is not the leverage your account allows but the leverage you actually use: the total size of your open positions divided by the money in the account. Open 0.5 lots of EUR/USD on a 1,000 dollar account and you carry about 54,000 dollars. Your real leverage is 1:54, even if the account allows 1:500.

On that position a pip is worth 5 dollars. A 20 pip move against you costs 100 dollars, 10 percent of the account. A 200 pip move, price shifting about 1.9 percent, equals the whole account. EUR/USD can move that much within a few days.

Now size the same account by the stop. The stop is 40 pips away and you risk 1 percent, 10 dollars. Size is 10 / (40 × 10) = 0.025 lots, which rounds to 0.02 on the platform. That position is about 2,160 dollars, real leverage of roughly 1:2. The account allowing 1:500 does not change that number.

If your margin level falls below the threshold your broker sets, positions can be closed without waiting for you. The threshold varies by broker. In crypto futures the same event is called liquidation. At high leverage, in a sense, the broker places your stop, and not where you would have chosen.

Sizing by free margin. Opening the biggest position the account allows sets your risk without ever thinking about the stop. The order is always the same: stop first, then risk amount, then size. Leverage comes in only at the very end, to answer one question: can I open this size?

Second, using leverage to grow a small account fast. The idea of multiplying an account quickly requires risking a large share of it on every trade. A few losses in a row and the account is too small to recover. An account that loses 50 percent needs a 100 percent gain to get back to even.

Third, using leverage on a trade with no logical place for a stop. If price has run for a long time without reacting, the nearest structure is far behind. The stop is either huge or placed somewhere meaningless. Leverage does not fix that; it only raises the cost of a badly placed stop. No logical stop means no trade.

A stop does not always protect a leveraged position. On news or across a weekend gap, price can jump past your stop and the loss goes beyond the 1R you planned. The bigger the position, the bigger the hit to the account. With some products losses can exceed what you deposited; the broker's terms tell you what protection applies.

Holding a leveraged position overnight has a cost too. In forex and CFDs it is called swap or financing, and on perpetual crypto futures, funding. These charges vary with direction and period. They look small for one day but add up over weeks.

Low leverage is not safety by itself either. Someone who puts an entire 1:10 account into one trade really is using 1:10. Someone sizing correctly on a 1:500 account may sit around 1:2. What decides it is not the broker's number but the size you open.
