I'm starting to dip my toes into the idea of day trading a bit. I think a good place to start is by watching the sectors. Should give me a good idea of where to start looking for specific stocks. I go into ToS and there's way more sector indices to watch. I was hoping to use these to narrow down what I have to look at but there are a lot of these too! There are S&P, NASDAQ, DOW and NYSE sector indices. Are any of these not worth watching and using to narrow down my search for opportunities? Diving into this world, it's so vast it's very overwhelming. Trying to do what I can to shrink it down to something more digestible and tangible. Any other advice/suggestions in regards to this would really be appreciated!
