    You can never predict the stock market, because the market depends on a lot of outside influences you might not know about. Maybe some disaster wipes out the only supplier for a critical part of your top performing stock tomorrow, so he cannot deliver goods anymore. Maybe a single big investor dumps all his stock overnight, sending the value down. Maybe some law or sanction is passed that changes how the company must operate. Maybe some other trading bot decides to buy or sell a huge number of shares.

    No computer or AI can account for all of the outside factors and accurately predict the outcome each time. Each “Trading AI” is just snake oil that lives of your fees and commissions. If it was working as advertised, they would not need your money, but could make infinite riches by just trading their own stocks.













  • You never worked on old code. It’s never that simple in practice when you have to make changes to existing code without breaking or rewriting everything.

    Sometimes the client wants a new feature that cannot easily implement and has to do a lot of different DB lookups that you can not do in a single query. Sometimes your controller loops over 10000 DB records, and you call a function 3 levels down that suddenly must spawn a new DB query each time it’s called, but you cannot change the parent DB query.
