I day trade mostly with some swing trades. RSI indicator from tradingview to watch on multiple similar stocks, indices, and etfs. For example, my bae is NVDA. I'll watch SOXX, SMH, Nasdaq, and a few more big boy semiconductors who move in tandem. If the past few days the S&P has kinda been down, then the first hour or two RSI is strong with its buy pressure i'll dump in heavy for an hour or two, gain 1% and dump it all the same day. 1% or 2% gain is a fat success in my book for one day. I trade with 100k and use 50k for the day trades to not get into a violation for free riding. I love that stocks settle only 1 business day now.
