I have the pivot points (up to 4 deep) on my chart but IMO the previous day(s) reversals, high, low and close are better 'pivot points'.
That may well be the case and shouldn't be too difficult to test. If you wanted to test it and produce hard empirical figures from it then you could use the same methodology that I used for testing the pivot points: i.e. there are 2 undisputed resistance and support points during the day which are the high and low (assuming that we don't close on the high or low). Measure how often these two points are within a certain number of ticks of one of your premeasured support/resistance lines - no matter where you get them from.
