AUD/USD is like most of the majors: smack in the middle of recent trading ranges. Since prices first moved below their 10-day moving average last week after trading above it for a month, the shorter average has been falling and it is now within striking range of sinking below the 21-day moving average in the next few sessions. A bearish cross may prompt some long-liquidation from systematic traders, so it is worth keeping this in the back of you mind.
