What Is Drawdown in Forex Trading (Australia, 2026)

Summary, drawdown for Australian retail traders

The five-line version:

• Drawdown is the percentage decline from your account’s peak equity to its lowest subsequent point, before a new peak is set
• Maximum drawdown is the largest such decline over the life of the account
• Current drawdown is the live distance from the most recent equity peak
• Recovery maths is asymmetric: a 25% drawdown needs a 33% gain to recover, a 50% drawdown needs 100%, an 80% drawdown needs 400%
• ASIC’s 50% margin close-out rule caps how far an ASIC-regulated retail account can draw down before positions are auto-liquidated, so you can’t normally drift quietly to zero

Drawdown matters more than win rate. A strategy that wins 70% of the time but takes a 60% drawdown when it goes wrong is worse than a 45% win rate strategy that caps drawdowns at 12%. The first one blows up the account. The second one survives to compound.

What drawdown actually measures

Drawdown is a peak-to-trough metric. You start tracking from the last equity high. The drawdown is the percentage fall from that high to the lowest equity point that follows, measured before the account makes a new high.

Once a new equity peak is hit, the drawdown clock resets and the previous figure is logged as a closed drawdown.

Two flavours matter:

• Maximum drawdown (MaxDD), the worst peak-to-trough decline the account has ever recorded. This is the headline strategy stat.
• Current drawdown, how far below the most recent peak the account is sitting right now. If you’re at the equity peak, current drawdown is zero.

You’ll also hear “average drawdown” and “drawdown duration” (how long the recovery took). Both useful, but MaxDD is the one that gets quoted.

A worked AUD example

You start with AUD 10,000. Here’s how a typical year might play out:

The maximum drawdown for that year is 25%, recorded at month 4. Even though the account finished up 20% on the starting balance, the worst point along the way was a 25% loss from the AUD 10,000 starting peak. That’s the number a fund-of-funds or prop desk would care about, because it tells them how much pain the strategy can produce on the way to the result.

Why drawdown matters more than win rate

Win rate alone is a vanity stat. Two strategies can have the same win rate and produce wildly different drawdown profiles. The one with the smaller MaxDD is almost always the one you want to run.

The reason is the recovery asymmetry. Losses compound against you faster than gains compound for you. The percentage gain required to recover a drawdown is always larger than the drawdown itself.

The maths: if your AUD 10,000 account drops 50% to AUD 5,000, you don’t need a 50% gain to recover. You need to double that AUD 5,000 back to AUD 10,000, which is a 100% gain on the new lower base. That’s why traders talk about drawdown being “the killer”. It’s not just the dollar loss. It’s the size of the win you now need to climb back.

This is why professional risk management aims to keep MaxDD under 20 to 25% even when the underlying strategy could comfortably run hotter. Once you’re 30% down, your required recovery is 43%. At 40% down it’s 67%. By 50% the strategy needs to literally double the remaining capital to break even, which most strategies can’t do without taking risks they’d never take from a fresh start.

Acceptable drawdown by trading style

There’s no single “right” drawdown number. Acceptable depends on the strategy’s holding period, the leverage used, and the trader’s tolerance for variance. Rough industry benchmarks for an ASIC-regulated retail forex account:

Intraday strategies should rarely take big drawdowns. Their edge is supposed to be tight stops and high trade frequency. A 20% drawdown on an intraday strategy usually signals one of three problems: stops too wide, position size too big, or the edge isn’t there.

Swing trading can absorb wider drawdowns because the strategy is held through more noise. 15% is normal. 25% is the upper end before risk parameters need a review.

Position and trend-following strategies routinely produce 25 to 30% drawdowns even when the long-run performance is strong. That’s the price of holding through countertrend moves.

Drawdown and ASIC’s 50% margin close-out rule

This is the AU-specific bit that doesn’t apply to traders in other jurisdictions.

ASIC’s Product Intervention Order (in force since 29 March 2021 and made permanent) requires retail brokers to close out positions when account equity falls to 50% of the initial margin used across open positions. It’s regulatory, not broker discretion.

What this means in practice for drawdown:

You can’t quietly drift from a 60% drawdown to an 80% drawdown to a 100% drawdown on an ASIC-regulated retail account. The close-out rule kicks in and liquidates positions before the account can fully bleed out. Combined with mandatory negative balance protection for retail clients, you can’t normally lose more than the cash you deposited, even on a wild gap move.

Worked example. You deposit AUD 5,000. You open positions using AUD 1,000 of initial margin. Unrealised losses cut your account equity to AUD 500 (half of the AUD 1,000 of used margin). The broker must start closing positions, beginning with the largest unrealised loss.

The close-out rule effectively caps the drawdown that an unmanaged retail position can produce. It doesn’t replace position sizing or stop-losses, but it stops the catastrophic wipeout scenarios that pre-2021 retail accounts could fall into. See our leverage guide and stop-loss guide for how the close-out interacts with normal trade management.

Tools to track drawdown on an Australian account

The good news: you don’t need to calculate drawdown manually. Most platforms and third-party analytics tools track it automatically.

Third-party analytics

• MyFXBook, connects to MT4/MT5 accounts via investor password, tracks drawdown, win rate, profit factor, and most other strategy stats. Free for personal use. The standard tool for traders running EAs and wanting verified track records.
• FX Blue, similar feature set to MyFXBook, with a slightly cleaner trade-by-trade visualiser. Also free.
• TradingView’s strategy tester, backtesting drawdown on a Pine Script strategy, useful before you go live.

Broker analytics tools (AU)

Several ASIC-regulated brokers ship their own analytics dashboards:

• Pepperstone, Pepperstone Insights (Smart Trader Tools add-on for MT4/MT5) tracks drawdown, win rate, hour-of-day performance, and pair-by-pair P&L
• IC Markets, client portal includes a basic equity curve and drawdown chart per account
• CMC Markets, Next Generation platform’s account analytics tab tracks drawdown by month and instrument
• IG Markets, IG Academy and the Performance Analytics tab inside IG’s web platform
• FP Markets, MyFP Markets dashboard with trade-by-trade analytics

If you’re running a strategy seriously, set up MyFXBook on day one. The history is much harder to reconstruct after the fact.

Position sizing to keep drawdown under control

Drawdown isn’t something that happens to you. It’s the result of position sizes you chose. Under ASIC’s 30:1 cap, retail forex traders can still over-size dramatically if they’re not careful.

The standard professional rule is risk no more than 1% to 2% of account equity per trade. On AUD 10,000, that’s AUD 100 to AUD 200 of risk per trade. With a 30-pip stop on a major pair (where each pip on a mini lot is roughly AUD 1.50 at AUDUSD 0.65), that’s a position size of about 2 to 4 mini lots maximum.

The same maths in reverse. If you want MaxDD under 20%, and you can reasonably expect 5 to 8 losing trades in a row at some point in any strategy’s history, the per-trade risk needs to be 2% or less. Risking 5% per trade with the same losing streak puts you at 25% to 40% drawdown. That’s the territory where the recovery maths starts hurting.
