I think the difference here is one is talking about not trading during crazy times of crypto world itself and one talks about not trading during your best hours. Sometimes, people are not on their best case mentally, you might be tired, you might be angry at something, basically you might be either emotionally or physically in best shape and that means you are not in the best time of your life to trade, trades during those times usually end up being filled with emotions and result with bad results
One shouldn't let external emotions affect his trading, be they good or bad
It is a lot easier when you follow a certain strategy as in that case you can bravely ignore bad or good moods, dangers as well as pleasures, and do your thing (in this case trading) as good as ever. Otherwise, your trades will still be negatively affected regardless of your mental state, whether you are in a good mood or shape. Your "best time" may easily turn out overconfidence, resulting in as bad results (if not worse at all)
I agree with you guys and think that emotions shouldn't take precedance over cool head. Also you should determine the enter and exit point properly. Just don't give up if you lose. If you are a beginner it's hard to control your emotions.But without self-control you won't gain a profit.Also it'd be good to use support and resistance in trading. Recently i have read an article provided by Monfex where they state "A good rule of thumb is to set your stops at support since if the price falls to consolidate at the break and fall back to the resistance, you now know that there was no demand at that price and that supply is growing.". Do you guys agree with it ?
