If I understand, you are saying when longer term, you spend additional time checking back over your positions and maybe the markets?
I'm not informed on your approach to the markets. Unless you're an algo trader, if you post an annotated chart I would. Harris's book on Trading Exchanges and Market Microstructure is the reference and quite good. This is a draft copy. There's a taxonomy chart on the net that has a visual representation. To update it with today's landscape, one would have to assimilate Michael Lewis's Flash Boys.

We can have a whole lot of debate on whether trading 5 minute chart is better than trading hourly charts. I mean to say that a pullback looks like a trading opportunity on a smaller timeframe while it is just noise from a higher timeframe perspective. Both approaches work well. Some of us may be more tuned to a specific time frame.
Problem with Day Trading as a 9-5, is sustainability. I would suggest you work a 4 day work week, not 5, while you get started.
Market is very volatile right now. When market calms down, you will have to switch to swing trading to get the same points.
I traded many things; investing, swing trading, day trading, trading stocks, options, futures spread trading Intermarket commodities ... I started investing and swing trading before the computer was available for home use. I gave up on investing and swing trading about 2 decades ago; It didn't work for me. I have been day trading since then. some day traders just trade for 3 hours a day. I spend about 6 hours a day. Some day trade for about 10 hours a day. So you have flexibility as to how long you'd want to trade. Anyway, go and experiment and see which best suits you.
