Summary, stop losses for Australian retail traders
The short version:
- A stop loss is a pending order that closes a position automatically when the price hits a pre-set level
- Three working types: hard stop (fixed price), trailing stop (follows favourable moves), guaranteed stop loss order (GSLO) (broker honours the level even on a gap)
- AU brokers offering GSLOs: CMC Markets, IG Markets, easyMarkets, Plus500, Trade Nation. Most ECN/STP brokers (IC Markets, Pepperstone, FP Markets, Fusion Markets) don’t offer GSLOs.
- ASIC’s mandatory negative balance protection acts as a final backstop on retail accounts but it’s not a substitute for a real stop
- Position sizing is the other half of the equation: standard rule is risk no more than 1% to 2% of account equity per trade
The single biggest reason retail forex accounts blow up isn’t bad signals. It’s no stop, or a stop set on emotion rather than account maths. ASIC’s 30:1 retail leverage cap reduces some of the damage but doesn’t replace good trade management.
What a stop loss actually is
A stop loss is a pre-set instruction to close a position once the market trades at (or through) a specified price. You set it when you open the trade, or you can attach it later from the platform’s order ticket.
If you’re long EUR/USD at 1.0850 and you set a stop at 1.0820, the broker will close the position automatically the next time price prints at or below 1.0820. You don’t need to be at the screen. You don’t need to be conscious. The platform watches the price feed and triggers the order.
The stop is filled at market when triggered, which is an important detail. On a fast-moving market the actual fill price can be worse than the stop price you set. That’s slippage, and it’s not the broker doing anything wrong, it’s just how a stop-market order works.
Stop loss versus take profit
A stop loss caps the downside on a trade. A take profit (TP) locks in the upside at a target price. Both are pending orders. Most platforms let you bracket the trade at entry: long position, stop below, take-profit above. The trade then runs to whichever level hits first. We use brackets routinely on swing trades.
The three types of stop loss
Hard stop (the standard one)
A hard stop is a fixed price. You set it and forget it. Filled at market when triggered, with potential slippage on fast-moving prints. This is the default stop type on every Australian retail platform: MT4, MT5, cTrader, TradingView, and the proprietary platforms (
CMC Next Generation,
IG web platform, Plus500 WebTrader, eToro, Mitrade).
The hard stop is what most traders think of when they say “stop loss”. It’s the type referenced in every position-sizing formula in this guide.
Trailing stop
A trailing stop follows a winning trade in your favour, locking in profit as the market moves your way. You set the trail distance in pips (or points, or as a percentage). As the market moves favourably, the stop level ratchets up to maintain that distance. As the market moves against you, the stop stays where it last ratcheted to.
Worked example. You’re long EUR/USD at 1.0850 with a 30-pip trailing stop. Initial stop sits at 1.0820. Price runs to 1.0900. The trailing stop ratchets up to 1.0870 (30 pips below the new high). Price falls to 1.0870 and stops you out. You’ve locked in 20 pips instead of taking the original stop.
Trailing stops are useful for trend-following strategies that need to ride a move without giving back too much. They’re not great for chop, where the trail can get clipped on noise before the move materialises.
Most AU platforms support trailing stops natively. MT4 and MT5 trail client-side (the platform must be running for the stop to update), while cTrader trails server-side, which is more reliable.
Guaranteed stop loss order (GSLO)
A GSLO is the only stop that protects against gap risk. With a hard stop, if the market gaps over your stop level (over a weekend, or after a major news print), your fill is wherever liquidity returns, which can be far worse than the stop. With a GSLO, the broker guarantees execution at exactly the level you set, even if the market gap is huge.
The catch: GSLOs cost a premium. Pricing models vary by broker.
| AU broker | GSLO available | Pricing model |
|---|---|---|
| Yes | Premium charged only if GSLO triggered, refunded if not | |
| Yes | Premium charged at order placement, refunded if not triggered | |
| Yes (default on every trade) | Built into spread (no separate fee) | |
| Yes (called “Guaranteed Stop”) | Wider spread on the trade | |
| Yes | Premium added to spread when GSLO selected | |
| No (regular stops only) | n/a | |
| No (regular stops only) | n/a | |
| No (regular stops only) | n/a | |
| No (regular stops only) | n/a |
The pattern is consistent across the AU industry. Market-maker and hybrid brokers (CMC, IG, easyMarkets, Plus500, Trade Nation) offer GSLOs because they’re internalising the gap risk anyway. Pure ECN/STP brokers (IC Markets, Pepperstone, FP Markets, Fusion Markets, Global Prime) typically don’t offer them, because the model passes orders through to liquidity providers and there’s no mechanism to honour a fill price the underlying market didn’t print.
GSLOs are most worth considering for positions held over the weekend, around major scheduled news (US NFP, RBA rate decisions, FOMC), and on illiquid pairs prone to gapping. For intraday majors, regular stops are usually fine.
Mental stops are not stops
This is the section you skip if you’ve already worked it out, and the section that needs to be loud if you haven’t.
A “mental stop” is a level you’ve decided in your head where you’ll close the trade, but you haven’t placed an actual order. The intention is to manage exits manually based on price action.
We strongly recommend against this. The reasons:
- You can’t watch every chart all the time, and the market doesn’t wait
- Under stress (after a losing streak, around news, or when the position is bigger than you’d usually take), discipline collapses
- “Just one more pip” is the most expensive sentence in retail trading
- Internet, power, or platform outages mean you can’t manage the trade even if you want to
Use a real stop. Every time. The minor inconvenience of having to set the order is dwarfed by the protection it provides. We’ve seen too many AU traders blow accounts in 2024 and 2025 on mental stops that didn’t survive the moment of truth.
How to size a stop loss in AUD
This is where most retail traders get it wrong. The stop level should be set based on price structure (where the trade thesis is invalidated), and the position size should be set based on how much you can afford to lose if that level is hit.
The order of operations:
- Decide the dollar risk per trade (e.g. 1% of account)
- Identify the stop level (based on chart structure, ATR, or fixed pip distance)
- Calculate the pip distance from entry to stop
- Position size = dollar risk / (pip distance × pip value)
A worked AUD example
You’ve got an AUD 1,000 account. You decide on a 1% risk per trade, so AUD 10 per trade.
You want to long EUR/USD at 1.0850. The recent swing low is at 1.0820, so your stop sits at 1.0815 (5 pips below the swing low). That’s 35 pips of stop distance.
A pip on a mini lot (10,000 units) of EUR/USD is worth roughly USD 1, which at AUDUSD 0.65 is about AUD 1.54.
Position size = AUD 10 / (35 pips × AUD 1.54 per pip) = 0.185 mini lots
That’s a micro lot (1,000 units) of EUR/USD, give or take. Most AU brokers let you trade fractional lot sizes from 0.01 lots upward, so you can dial the position to the exact risk parameters.
If you’d skipped the maths and opened a full mini lot, your effective risk on the same 35-pip stop is AUD 53.90, or 5.4% of the account. Two losing trades in a row is over 10% drawdown. That’s the territory where the recovery maths starts hurting (see drawdown).
Where to actually put the stop
Three common methods, used in combination:
- Support/resistance, set the stop just beyond the most recent swing high (for short positions) or swing low (for long positions). The trade thesis is broken if price clears that level.
- ATR (Average True Range), set the stop at 1× to 2× the 14-period ATR away from entry. ATR scales the stop to current volatility, so the stop’s wider in fast markets and tighter in quiet ones.
- Fixed pip distance, simpler, less adaptive, but works for systematic strategies. Common defaults: 20 pips for scalping, 50 pips for intraday, 100+ pips for swing.
The structure-based stop is usually the most defensible because it ties the exit to a price level that genuinely invalidates the trade idea. ATR-based stops are second. Fixed-pip stops are third because they ignore volatility, but they’re easy to backtest.
Common stop-loss mistakes
Stops too tight (whipsaw)
Setting a 5-pip stop on a major pair where the spread alone is 1 pip and intraday noise is 8 to 12 pips guarantees you’ll get stopped out on flow that has nothing to do with your trade idea. The “whipsaw” pattern: stop hit, market reverses immediately, trade thesis was actually right, you’re not in it.
The fix: stop distance should always exceed the natural noise level for the pair and timeframe. If the 5-minute ATR on EUR/USD is 8 pips, your stop has to be wider than 8 pips or you’re paying entry costs to be stopped on noise.
Stops too wide (oversized loss)
The opposite problem. The stop sits 200 pips away because “the trade has room to breathe”, but the position size wasn’t reduced to compensate. Now a single losing trade is 8% to 15% of account equity. Three of those in a row and you’re in serious drawdown.
The fix is the position-sizing formula above. Wider stop, smaller position. Always.
Moving the stop further away from price
The cardinal sin. Trade goes against you, stop’s about to hit, you move the stop further out “to give it more room”. You’ve now turned a defined-risk trade into an undefined-risk trade. The original trade thesis was invalidated, but you stayed in.
The fix: never move a stop further from price. Move it closer (to lock in profit, or break-even after the trade has moved your way), but never further away. If the trade idea has changed and the new stop is genuinely justified, close the trade and re-enter with new parameters from a clean basis.
Not having a stop at all
The “I’ll just watch it” approach. Discussed above, but it bears repeating. ASIC-regulated retail accounts have negative balance protection and the 50% margin close-out as backstops, but those are catastrophic-loss safeguards, not normal trade management. The close-out triggers when account equity falls to 50% of margin used, by which point the account has already taken a substantial drawdown.
How ASIC’s 30:1 cap interacts with stops
Australian retail traders are capped at 30:1 leverage on major forex pairs under ASIC’s Product Intervention Order (in force since 29 March 2021, made permanent).
The 30:1 cap doesn’t reduce the importance of stops. If anything, it makes stops more important. Here’s why.
Under the cap, the position size you can open relative to your account is large but not extreme. On a AUD 1,000 deposit at 30:1 leverage, you can open up to roughly AUD 30,000 of notional EUR/USD exposure. A 50-pip move against you on that position, without a stop, is roughly AUD 230 of unrealised loss, which is 23% of the account.
The 50% margin close-out kicks in only at the regulatory threshold, not before. By the time it triggers, you’re already deep into drawdown territory. A real stop, set at a price level that invalidates the trade thesis, fires much earlier and at a much smaller loss.
ASIC’s protections are floor-level. Your stop is the operational tool. Don’t confuse the two.
