Most difficult to trade: S & P 500 index and E-MINI S&P 500 markets

Below are the charts of S & P 500 index ($SPX) and E-MINI S&P 500 (ES 1!).

SPX choppy trading very difficult how to trade quote chart
S&P 500 index ($SPX), 15 minutes chart
es chart volatile market manipulation futures quote chart impossible to trade
E-MINI S&P 500 (ES 1!), 60 minutes chart
I have been tracking these markets for the past 2 years and still find them to be so difficult to trade and analyze.

I lose my confidence in trading and at the same time the choppy trends in these markets pushes me to find a method, which can give consistent returns in such challenging conditions and scenarios.

If you have a system or currently developing one, do back test it with the market data of these two indexes.
Have fun :)
