The pair with a real Asian session
Australian data prints during the Asian session, and the Aussie is the major most sensitive to Chinese data and commodity demand — both of which land while London is asleep. So AUDUSD's Asian range is frequently a genuine directional move rather than the consolidation you see on the euro or cable.
That has a direct consequence for anyone testing session-based rules: "trade the London open break of the Asian range" is a very different proposition here, because the Asian range on the Aussie is not automatically a range. Backtest it with session boxes on and check that assumption before it costs you.
Commodity currency, macro-driven
The Aussie behaves as a risk-on proxy: it strengthens when equities and commodities do and falls hard when they don't. Practically, that means AUDUSD trends can be persistent and macro-driven rather than technically self-contained, which suits trend-following rules and frustrates pure mean-reversion ones.
It's also generally a lower-volatility major than GBPUSD, which changes stop sizing rather than strategy — size each test through the position size calculator and check the pip value with the pip calculator so your R values are real.
Frequently asked questions
Can I backtest AUDUSD for free?
CRTLAB is free to try. You get AUDUSD across the full archive, with every tool the product has, for your first 10,000 candles of replay — roughly two hours of stepping through a chart, no card needed. After the sample, unlimited replay is $14.99 a month, cancel any time. The Asian session is where this pair does most of its work, and the archive covers it in one-minute detail rather than skipping to London.
Should I backtest the Asian session on AUDUSD?
Yes, and separately from London and New York. It's the one major where the Asian session frequently produces the day's directional move rather than a consolidation range.
How does AUDUSD compare to EURUSD for backtesting?
Lower typical volatility, a more meaningful Asian session, and stronger sensitivity to commodities and Chinese data. The same technical rules produce genuinely different numbers — running both is the cheapest way to see which your method fits.
