These "tricks" you've listed really aren't "tricks", they're pretty much just generic trading advice. Not to mention these "tricks" shouldn't apply to every situation. It hugely depends in many factors.
I was going to say exactly that, this are not tricks, rather basic guidelines which are very common, and over emphasized.
A trader has to be flexible, especially when handling different currencies. Tricks oe strategies do not apply for every coin or token as they are all unique.
As a trader look for the strategy that works for you and stick to it.
