There is no 'lucky person in trading, they have worked for it, they lost a lot before they will finally analyze the market, they have been stressed, depressed, most of the time they have lack of sleep, if they have predicted the market right, it is because they have studied it well, they did their best for them to be able to earn and to become successful in trader, so kudos and thumbs up to them as it is not that easy.
