Bots are generally closely guarded secrets because they're so powerful. They take away the emotions of trading, so you can set a strategy and just let it go
I am seriously uncomfortable with the entire thing, to write for Devtome forces me to become a currency trader, something I wouldn't do in any other environment to get paid for my work. I suspect a lot of newcomers are going to be challenged by it as well so a bot would be awesome and might make this just a little less traumatic for some of us

If you are able to make one for commercial sale, would it ever be affordable for a writer or developer being paid in DVC?
The thing with markets is you'll never know if you're actually taking advantage of fear or if you're simply providing liquidity (ie someone is genuinely purchasing/selling them for an intended use). It's a bit like how some countries have the practice where there's only one real bullet in a firing squad, so no individual shooter knows if they were the one that took the life.
I think though, that real success in trading means actually hoping and even being a bit delighted by fear/negative forces to help with that success. In the end, those who might not be as hard-nosed or cant afford to lose so they react to fear, are always going to be the losers. (IMO)
