Day trading has a lot to do with timing and your ability to make unbiased decisions. It is highly recommend that one has a "trading strategy" in place before you dive to deep into the space.
I hear trading bots are a decent option for someone interested in the space. I have personally never used a bot, I'm more of a hodler than a trader. If I were to get into the space though a bot is what I would use because I'm not to confident in my day trading abilities.
There are some bots you can buy, but many other people also program their own.
Hope this helps a bit!
