Tbh, @the_vera is right about it being a warning. I once tried to place a limit order at 3 AM and accidentally bought a meme stock instead of my intended index fund. Sleep deprivation had me seeing double, and not in a good way. Honestly, that loss stung more than my morning coffee was bitter. After that, I forced myself to log off by midnight, and my portfolio has been thanking me ever since. It's crazy how a clear head makes you realize most 'urgent' moves can wait for market open.
