Looking to perfect (2) strategies - dip buying into clear support levels 15-30min after market open & swing trading reverse split pumps.

This morning, I was looking for a clear dip buy into morning resistance on premarket runners.  The (3) stocks I was looking at was ONVO, LGVN, HUBC.  I need to do a better job of making clear watchlists and watch (3) stocks maximum at market open for potential dip buys into clear prior resistance.

I went with ONVO, which had a catalyst/ PR of positive mid stage results in their phase 2 clinical trial.  I liked the catalyst and thought the stock could DNR for a 10-25% run.

LGVN did a PR last week to complete and offering then is PRing again this week.  A pump and dump and pump.  But even with the shadyness of the company, the stock ripped from testing premarket low at $2.21 up to market high of $3.41 (50%+) and could have easily hit my 10-15% profit target.  Good entry would have been first 5 min of market open and could have had a tight stop loss with clearly defined risk/reward.

HUBC retested premarket lows from 30-45 min after the open and ran up 25% from bottom to top.

I took a small swing position for a lesson on MYSZ stock split news, trying to understand how to get good entries on stock split pumps, hoping for a company PR sometime this week.
