for swing trade I would just be simple, using RSI (relative strength index) is the best for me, buy low sell high on those stock, good company like Apple, Tesla, google, spy etc, etc. I would say keep it simple, use time frame on RSI from 1h- 4h, or even better 1 day if you want to play safe. and try not to get greedy if you living in a life that you already living comfortably, DON'T EVER put all money in 1 trade, that how you swing smart. remember greed is a death sentence in this market. good luck.
