Margin and leverage: what is actually tied up

Updated on

The short answer

Leverage lends you nothing: it sets the share of the position your broker freezes on your account, called margin. At 30:1, one lot of EURUSD, meaning 100,000 euros of notional, ties up about 3,300 euros. The point almost nobody makes: leverage does not change your risk, which depends only on the distance to your stop and your size. It changes what you are allowed to open, and that is where it becomes dangerous. In Europe it is capped by regulation, from 30:1 on major pairs down to 2:1 on cryptocurrencies.

Margin, leverage, notional: three words for one division

The notional is the value of what you control. One lot of EURUSD is 100,000 euros, whatever your account.

Margin is what your broker freezes to let you hold that position. It equals the notional divided by the leverage: at 30:1, 100,000 divided by 30, so about 3,300 euros.

That sum is neither lent nor spent, it is frozen. It comes back to you when the position closes, increased or decreased by the result.

The European caps, by asset class

A retail client of a European broker does not get the leverage they want. Regulation caps it, and the cap depends on what you trade.

That is why a position on Bitcoin ties up half its value, where the same amount in EURUSD ties up only a thirtieth. Negative balance protection is added on top, stopping a European account from going into debt.

Leverage does not change your risk

This is the most widespread misreading in the business, and it is worth stopping on.

What you lose if the market goes against you depends on two things only: the distance between your entry and your stop, and the size you opened. Leverage appears nowhere in that calculation, set out on our page about risk per trade.

Two identical accounts, one at 30:1 and the other at 5:1, taking the same position with the same stop, lose exactly the same amount. The first simply has less money frozen meanwhile.

What leverage changes is the maximum size you are able to open. High leverage makes a position that is disproportionate to the account possible, and it is that oversizing that ruins people, not leverage itself. Leverage is not a risk, it is a permission.

Free margin, margin level and forced closure

Your platform shows several numbers worth knowing how to read.

Free margin is what remains available to open something else. The margin level, as a percentage, relates your equity to the margin used: it falls when your positions lose.

Below a first threshold, the broker stops accepting new positions and issues a margin call. Below a second, often half, it starts closing your positions itself, generally the worst one first. Those two thresholds vary from broker to broker and are in your account terms.

What matters is that a forced closure does not wait for your stop: it happens because the account can no longer carry the position, which is a different problem.

When margin gets an order refused

That is code 10019, and it often surprises because the order looks reasonable.

Two situations come up. On an instrument with capped leverage, the margin required is far heavier than people imagine. And on a plan with several targets, the earlier legs already tie up margin, so the last one falls below the threshold while the previous ones went through.

The rest of the refusals are covered on our page about MT5 return codes, and the size calculation on the one about position size by instrument.

What AlphaGPT does

The size offered is computed from your account’s real equity and the risk percentage you set, never from what your leverage would allow. That distinction matters: the question is not “how much can I open” but “how much can I lose”.

When an order is refused for insufficient margin, the cause is shown in plain words rather than as a code.

On the other hand, the tool does not know your broker’s margin call thresholds and will not warn you of a forced closure coming: that is watched in your platform. Trading carries a risk of capital loss.
