PipWardenWhat is negative balance protection?
Definition Negative balance protection is a rule, or a broker policy, that limits a retail client's losses on CFDs, including rolling spot forex, to the funds in the trading account, so a fast market cannot leave the client owing the broker money.
Negative balance protection is a rule that stops a retail trader from losing more than the money in the trading account: if a fast market pushes the balance below zero, the broker cannot claim the difference. For retail clients trading CFDs, which include rolling spot forex, it is mandatory in the EU and in Australia.
How a balance goes negative
A stop loss and a stop-out both close positions at the next available price. If the price jumps past them, after a weekend gap or a surprise announcement, the loss can be larger than the money in the account. A stop is a trigger, not a promised price: once it is reached, the order executes at a price that “could be markedly different than your stop price” (FINRA). That difference is slippage.
In MT5, a negative balance shows as a Balance below zero on the account line of the Trade tab (View → Toolbox, or Ctrl+T).
The rules in the EU and Australia
EU. ESMA made negative balance protection a condition for selling CFDs to retail clients from 1 August 2018, “on a per account basis” (ESMA). The decision limits the client’s “aggregate liability for all CFDs connected to a CFD trading account” to “the funds in that CFD trading account” (ESMA notice). National regulators replaced ESMA’s temporary measures with their own between March 2019 and April 2020, and as of February 2026 ESMA lists negative balance protection among them.
Australia. ASIC’s order, in force since 29 March 2021, protects against negative balances “by limiting a retail client’s CFD losses to the funds in their CFD trading account” (ASIC). As of October 2026, the order runs to 23 May 2027, after a five-year extension.
Both rules come with leverage caps and a margin close-out, at the latest once equity falls below half the initial margin, which aims to close positions before the account runs out.
What negative balance protection does not cover
| Covered | Not covered |
|---|---|
| A negative balance on a retail client’s CFD trading account | The money in the account, which can all be lost |
| All CFD positions in that account together | Money or assets held for other purposes: ESMA’s Q&A counts only cash in the CFD account and open profit or loss |
| Retail clients | Clients treated as professional, who are outside the retail rules |
The protection comes from the regulator of the firm that holds your account, not from the brand name on the website. Check which entity your account is with and what its client agreement says.
A common mistake
Treating the protection as a reason to size up. It only removes the debt beyond zero. The account still goes to zero first, and a strategy that relies on it has already lost everything in the account.
For an automated system, a stop loss on every order is the first line, and it can still fill past its level. PipWarden attaches a stop to every order and checks your limits before each one, but it cannot stop a gap: open trades run to their stops, and prices can jump past them. The margin calculator shows how close a position is to a stop-out, and why most forex traders lose money covers the leverage caps, the margin close-out and this protection together.

Does negative balance protection stop me losing my deposit?
Educational content, not financial advice. Forex and CFDs are traded on margin and are high risk: you can lose money, and more than your deposit with some brokers. Examples use made-up numbers and show no real results. Read the risk disclosure.
