Choppiness of Intraday Charts for Global Macro Instruments

I have noticed that intraday charts for global macro instruments have become more inconsistent recently with lots of whipsaws, especially in recent years (2015). When I first traded in early 2011, these markets were not as choppy. What happened?

For instance, FDAX (DAX futures) can whipsaw around a range for about 2-3 hours at times, with many significant breakouts and pullbacks failing or getting faded at insignificant areas. In late-2013 to early-2014 when I first found success trading the DAX markets, things weren't like this. Pardon my lack of understanding of market dynamics, but what is causing these changes with lower time frame charts getting more choppy?

Also, would any stock traders here advise for me to make a switch to trading stocks? I started trading global macro due to the amount of leverage and low costs provided through CFD and Forex brokers. I am not sure about the world of stock trading, and if margin is offered today in 2015. I am looking forward to hearing the community's advice.

I am open to criticism, and I look forward to learning from those kind enough to reply.

Thank you very much!
