Do not rely on luck, I have seen some traders relying on luck hoping to make some bucks, but it will never end up well if you do that. Try to find the analysis in your trade, read the chart, view the pattern and see what analysis is talking about.
Traders should never rely on luck actually. The price movement is a regularity which implies that the price is moving accordingto particular events in the economy of certain countries or in world economy. Moreover, traders should never think that forex traing or crypto trading are easy, and you can earn there fast money. It's not like that at all and if you will think this way you will never face goo sums of money. To my mind, all traders from time to time think that getting money is an easy process, nevertheless, it lets them down a lot.
I think that you have to be rational and rely only on the results of your nalysis and your personal knowledge and skills.
Absolutely, but anyway stop loss matters a lot in case we speak about not only new traders, but professional as well. No doubts, when you're already a professional trader you feel like you can capture the whole world, you feel superpower, nevertheless it's also a serious mistake.
I personally believe that when you feel like you own superpower, it's time to take a break from trading for a while, because such behavior can easily lead you to huge losses. To my mind, the best option to avoid overtrading is to comply with regimes of relaxing and working. Actually it's suitable for any kind of activity.
