Thats why profesional trader which living from trading. They dont wacth chart whole day. They only take 2-3 hours to analyze market and making decision at what price they want to enter market. And then they set the stop lost after calculating the risk factor. They wont use very big matgin. They have good risk management base on their money.
Most that I know use most of their time in taking analysis and watching the market. But that's for sure that they're making their decision before entering the market firmly.
They don't buy because of the hype but instead, they're taking those moments to sell while the hype is there and AFAIK, they're percentage based in taking profits.
Pro traders are smart people, they know what they are doing, and they'll make decisions wisely that give them more profit than suffering losses. Actually, they keep an eye on every market change, yeah, they are taking their time to watch the market, not on social media, and probably they don't watch the news. I'm not going to say that they are stress too much, it couldn't be as they are enjoying what they do.
What makes an unhealthy life is when we have a lot of problems and we never know how to solve them, that gonna kills us.
