Automated trading
Automation eliminates emotional mistakes and replaces them with technical ones. It's useful for discipline and doesn't solve the problem of actually having a viable strategy.
A program sticks to the rules, even at night, even after three losses. That's the real advantage over a human, and it's not a small one.
What automation can't do: make a bad strategy good. A program just executes a negative expected value more reliably. The question of strategy therefore still comes before everything else.
New sources of error come with it. Dropped connections, wrong order sizes from a typo, an interface that changes, a program that double-buys after a crash. Such mistakes happen fast and at scale.
And a warning about purchased bots: if someone's selling a program that reliably makes money, ask why they're selling it instead of using it themselves. Nobody has convincingly answered that question yet.
The benefit of automation lies in eliminating the gap between a defined and an executed strategy. Since a meaningful share of the documented return gap for retail investors comes from exactly such gaps, this effect is quantitatively significant, regardless of the strategy's own quality.
The operational risks introduced require their own safeguards: caps on maximum order size and daily count at the system level, reconciling actual positions against the expected state, defined behavior on connection loss, and a manual kill switch. Without these, a single failure can exceed months of gains.
Economically, the incentive structure of sold systems deserves scrutiny. A provider with a genuinely viable strategy would have an incentive to manage capital rather than sell software, since a working strategy's earnings scale with capital deployed, while software sales only scale with customer count. The sale itself is therefore a signal about where the real revenue comes from.
Summary
- Automation solves the discipline problem, not the strategy problem.
- Technical failures act fast and at scale.
- Anyone with a working strategy wouldn't be selling it.
Did you get it?
Where does automation's real benefit lie?
In eliminating the gap between a defined and an actually executed strategy.
What safeguards does an automated system need?
Caps on order size and count, position reconciliation, defined behavior on connection loss, and a kill switch.
Why is selling a trading system a warning sign?
Because a working strategy's earnings scale with capital, while software sales scale with customer count instead.
