Yummyfajitas, that's exactly why I do not want human input. Also, I'm not trying to make money on every bet, but to make more money in my winning bets (less fees) than I lose in my losing bets.
What I'm trying to convey is that you do have human input even for a pure algo strategy. If you acknowledge it exists, attempt to minimize it and manage what remains, you are far less likely to have it cause you problems.
