You show the entire day, so its obvious what happened. If you look at what I posted, there are several instances where price did in fact make a lower low (ie. dipped below the previous low), but then came back up again and made new highs. So at first it looked like a reversal, and then that reversal failed and the original trend continued.So, have we a reversal or a pullback?
The secret is you will never know. All you can do is place a trade in an area that gives you a statistical probability that over time, you will make more money on trades that work than on trades that don't work. Where those trades are placed is where the hard work comes into play.
When you talk about specific examples, like your chart, now you really need to get into context. This may be a nice trend, which you know in hindsight, but if you had previous resistance levels that you were aware of, taking shorts would make sense. At the same time, if you knew that we just broke out of some sort of resistance, then it would make sense to think we are trending now and you could buy each of those pullbacks.
The secret for today was knowing that the high for yesterday was 1883, and once we hit this level and couldn't drop below, it made sense to think of a reversal there. So although as price was dropping down to this level throughout the morning and you could be thinking of going short on each pullback, once we hit this level, being on the lookout for a reversal trade is where the money was.
