Dislikedhm, yes, that's a good "guideline". I say guideline here, because I would say trend change is always a grey area. Sometimes it's easier to recognise a trend-change than other times. So, yes, a good guideline.
Anyways, everything in trading should just be a guideline, those hard rules almost always have lots of exceptions.
Yeah, the second rule / guideline is also important I think, it comes down to historical significance again. We need to see how people reacted in the past to "predict" how they could act in the future.
