In one of her books binary/FX trader Anna Coulling says to importantly trade on volume & price. She talks as if the charts represent the volume of traders trading at any given price point. She goes on to describe the charts as a tug of war between buyers & sellers. She even talks about entering trading when certain world currency markets open or overlap in time, thus providing a greater probability of achieving trade volume.
My understanding is that the charts only represent the value of currency exchange rates at a particular time point in real world economies, and that the volume (number) of traders buying & selling binary options do not affect the value of charts at all.
Could you please comment on these seemingly conflicting statements?.
