  • This question is too broad to answer, in my opinion. It would require a dissertation on Smart Contracts, DAOs, HFT and how to design/create software. It's not obvious to me that a trading bot would need even a contract or a DAO or what their roles would be. Many trading bots exist without Smart Contracts. – Rob Hitchens - B9lab Feb 4 '17 at 19:09
  • @eth: I have narrowed the question by making it "binary," and wonder if can be re-opened in its current form. – Tom Au Feb 5 '17 at 11:25
