For pure intraday traders, the daily pivot point is most valuable indicator by far... there is not even a close second to it.
Taking long trades into pullbacks with price action above the pivot OR short trades into lifts with price action below the pivot will keep intraday traders on the correct side of biggest price swings far more often than not.
Use the pivot as your 50-yard line, learn to persistently short below it and buy above it. That's where the easiest money is more often than not, and <i>more than not</i> is a profitable edge.
