A good Argentinean company to invest in is Mercado Libre, the country's leading e-commerce and online payments company, but you peasants should know investing is for those with substantial funds, not 'normal people'.
When I used E*trade it would do that on the busiest down days like during March 2020 or any time S&P opened something like -2.5%. So it seems more like their back end isn't good enough. Maybe that's why they were bought by MS
Gamestop's story is over. They aren't even trying anymore. At least initially they pretended they were expanding e-commerce and doing an NFT market. The only thing they can sell is stock to apes.
