I'm trading breakouts at the open on both GBP/USD and EUR/USD using the london forex open system which has always been a pretty reliable indicator of early morning movement. However I've noticed that recently that the market has really struggled to make up it's mind which way it wants to head after the bell.
I think it comes down to the fact that each piece of news is being seized upon at present with a view to a solid trend forming. I did read an article a while back which drew a curve showing volatility increasing over time in markets as a natural cause of news flow and increased manipulation.
