Earlier quoted context omitted.
Sure, but 80 -> 28,000 -> 54,000 is a hell of a lot of slippage. Trading platforms can guarantee a maximum slippage on stops, and often even offer guaranteed stops (with an attached premium), so I don’t see why Google and Firebase can’t do similar. The way it works at present is ridiculous.
> Trading platforms can guarantee a maximum slippage on stops Yeah no, physically impossible. If nobody is selling at that price, there is no guarantee your sell stop will execute near that price. They can sweep the market, find the best seller price and execute. There might be a costly way to do it with microservices as I indicated, but your example easily falls apart.
Cloud providers would be taking way less risk interacting with their own services than a broker does interacting with the market. Perhaps they would be more at risk from bad actors, but it shouldn't be significant: they could reserve this behaviour for people who have already spent, say, $100 with them so you can't abuse it at scale.
