I think this comes from experience with the market you trade. You get to know its mood and sentiments over time. You know when news or the timing of things just puts people on the sideline and the chop ensues.
Using an indicator to tell you from a historical perspective what is happening now seems a bit silly when you really think about it. You have to be in tune with the market. This will come but it's a matter of time. I would get a good charting program and open a 100$ CFD account to keep it real, and then just put the time in until you inherently understand the market you trade. A windsurfer doesn't need an oceanographer to come out and do some measurements to see if the water he's in is choppy, it becomes obvious through experience.
