As Senior Trader the most important things I do are spotting and trading opportunities. At the same time I have to keep track on what our junior traders do and guide them. What I like about this work is that you see immediate results of your actions. At the end of the day you see what decisions and positions paid off. My job is most challenging when the market crashes, but even on quiet days no day is the same because of company related news, macro events or trading interests in the market. All the time you have to be sharp and see opportunities before others see them.
