I Missed a Huge IPO Opportunity, Feeling Dumb Right Now :(

First off, please don't take anything I say seriously or as financial advice. As always, this is on an opinion based basis. That being said, imagine having a chance to buy a stock at a $13 price point and doing a sell of for $42 within a day's time period. Had the chance to do that, and didn't. Didn't even get the stock. When you see a stock going down few hours Post-IPO, it is because many people are putting sell orders quick for profits and lots of activity happening during those time periods. Unfortunately, it can mess with your confidence and your judgement where you miss a great buy opportunity. I seen the stock's symbol from TradingView. It had hype. Now, I feel sick :(
