The S/R I use myself is the simplest: swings high and low by prices.
Obviously historical S/R doesn't always become future S/R, but it does often enough to be highly significant.
I always envisage an increased probability of historical S/R becoming future S/R if it's (a) recent and/or (b) multiple.
I always look at S/R levels as "very thick, approximate lines" or "zones" rather than ever expecting them to be absolutely accurate.
In some markets, with a daily close (this doesn't apply so much to the futures I trade, where realistically the daily close is more or less that of an underlying rather than that of the futures themselves) I regard "the close" as a possible area of future S/R, too. For example, if trading the Dax index, I'd always know the previous day's "Frankfurt close" figure, in case it turns out to be relevant. Years ago, I used to trade the FTSE-100 and FTSE-250 indices, for a while, and was continually impressed by what a significant figure the "London close" often turned out to be. I haven't really seen this discussed in any books or forums or anywhere, but I do think there's something real behind it. That said, it may be less significant now than it was a decade ago. I don't know.
My attitudes and beliefs about almost all trading matters are only evidence-based ones, so I have almost no respect at all for, or interest in, any other kind of "pivot points" at all (doubtless
many people will disagree with me about that, of course: nothing new there
) and I've never seen anything other than anecdotal evidence for them, myself. But there you go: thousands of people trade according to phases of the moon, "Elliott waves", "Fibonacci numbers", astrology and probably homeopathy, too.
