The AUSSIE200 fell away dramatically this week. On the weekly chart we can see a very clear and obvious Bearish Engulfing Bar that gave traders a chance to take part in this huge sell off.
Often you will hear traders talk about what the news made the market do etc. I am of the very firm belief that solid knowledge in Price Action is what a trader needs and that price will often give clues to large moves such as this.
