Nothing new here.
Bottom line: How can one survive (no, profit) at a year of the two sideways and trending markets? You can't see what's going to happen before it occurs.
The answer is: Run two distinct egies on two distinct accounts... one which works in trending, and one which does well in sideways.
Trade both with high leverage, and try to compound the crap out of one of both accounts.
When it happens to be quite choppy or good trends, an individual will outshine the other with some sort of exponential parabola. An individual can get crushed while the other is making a killing.
Nownothing lasts forever, so at any stage you want to take everything off the table and begin over.
The Risk: several flip flops between trending and sideways markets should cripple both accounts. However, you knew that before you began, right?
Constantly open to debate and agreement-- what could you do in this crazy game we are in?
