The Aussie is one of the main currencies to watch over Chinese GDP data

Bloomberg's economic market impact monitor is a handy guide to gauge the price action in various instruments over data points. You may have seen me run it for NFP.

I've thrown Chinese GDP and the aussie at it and here's the response for the last 4 releases over the first 5 minutes and first 60

Chinese GDP vs AUDUSD over 5 minutes

Over 60 minutes

It's not a definitive signal of any kind, and we have to take into account which way the market is leaning into the event. At the moment that lean isn't towards China coming out with 8% growth ;-)

Just for kicks, give me your guess for the pip size of the first 5 minute candle in AUDUSD following the release. I'll go 110 pips
