It seems like he wanted a bot that works. To me that sounded like he just wanted a bot. He didn't say anything about algorithms. It's a bit like buying a racecar, to win races you need a driver that's good at the track, and likweise for the bot, you need to have algorithms that are actually profitable.

So perhaps what he wanted was just a bot, and then he wanted to add his own rules for how it should do trading ?
