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?
I may be able to write up a quick PHP implementation of the EMT volatility bot, and people could deposit their devtome DVC and the bot could trade their DVC online. Shares of the trading profit could be sold as well, which would give Hunterbunter another six shares too!
