The type of set-up I am looking for is, to me, a continuation. But to some people the little down move I am aiming to hover above may be something else. In ticks my pullback could be a reversal, the whole downtrend, base and breakout into an uptrend could also be a reversal. However, looking at a bigger picture this reversal could just be one part of a low volume pullback after an upbreak from an extended base. Is this what is meant by forests and tress?

I wasn't going to re-enter this particular fray, but since you've made the effort to answer sulong's original question, congratulations are in order. All other considerations flow from the ability (and the willingness) to distinguish between a retracement and a reversal. If one hasn't done that, then he's going to be swimming with ankle weights. In a heavy robe. Tied to the pier.
You've made an excellent start by defining the context, and I'm assuming that if this particular setup were not to occur off a base at potential S (note I said "potential") after a downtrend, then you would not consider it valid.
However, you're getting tangled up in the politically-correct definitions of reversal, retracement, pullback, continuation, trend, breakout, etc. I suggest that you avoid this since these are all only labels used to describe what it is you're seeing in the charts. What matters is what you see, not what you call it, at least until you want to discuss it with somebody else, in which case you simply provide your own set of definitions. In other words, you decide the rules of play. If someone wants to talk to you, they learn your dialect.
So.
You say "the type of set-up I am looking for is, to me, a continuation". Note the words "to me". And if this is how you want to define "continuation" in your own mind in order to sort all this out and make sense of the tactic set you're trying to develop, then that's fine. But first you need to think about what it is that you want to see continue. I assume that you mean the direction in which you want to see price move, in which case, you're going to have to think about the context.
For example, if you consider the up and down movements within a trading range to be uptrends and downtrends, then the bounces off S and R might be considered reversals. If the subsequent move is a trend, then any counter-trend movement is a retracement, and any resumption of the trend is a continuation. However, if the movements up and down within a trading range are not trends but just bounces back and forth, then any entry you make is part of the previous reversal and need not have anything to do with retracements and continuations, depending on how you're defining all these terms.
What difference does all of this make? Probably none, if you're a scalper. But if you want more than that, you're going to have to consider probabilities, factor in your price targets, the width of your stops, your win:lose and profit:loss ratios, the strength of your initial setup, etc. For instance, if you can enter the trade very near S, and R is enough of a distance away to make the whole thing worthwhile, that will be more attractive than an entry made halfway through the trip from S to R, much less an entry made very near to R, i.e., your target (perhaps).
On the other hand, if you decide that trends take place only outside of ranges and that retracements take place only after price has broken out of the range, a new set of possibilities is available to you, not the least of which is that you have no set price target. You may decide that that "retracement" that you're buying after the bounce off S is just a higher low and of no particularly cosmic significance. If price wends its way toward R, fine. If not, you've planned for that contingency. But by not thinking of the move as a "trend", you avoid some of the usual pitfalls, such as confusing trend with chop, and getting lost in increasingly smaller up and down movements.
There's more, of course. But this is something to chew on over the weekend.
