Stock market trading systems, so I don't have to watch screens, also backups and also constantly improving monitoring for smooth operations
PS: anyway, sorry for digressing away from the topic of the HN thread lol
I was writing that script for Amibroker platform (https://www.amibroker.com) but I believe the market leader is probably something like MetaTrader (https://www.metatrader4.com). Also, for developers or software engineers familiar with Python, Quantopian might be something you'll enjoy using (https://www.quantopian.com).
