The logic:
- If you can’t tell a machine how to perform your strategy, then you simply don’t have a strategy. Strategy = clear rules. No clear rules = no strategy.
- If you do have a strategy, but insist on performing it yourself, your emotions will inevitably get in the way, sooner or later. Automation is the best way to prevent it.
- Most strategies can’t be reliably back-tested manually. No reliable back-testing = loss.
