Programmatic trading
Trading where software places the orders. It describes the execution layer, not how the decision was made.

What it is
Programmatic trading is trading where a computer sends the orders, instead of a person clicking a button.
It answers one question only: how did the order reach the exchange.
The distinction that matters
| Layer | Question | Term |
|---|---|---|
| Decision | How did you decide what to buy? | Quantitative trading |
| Execution | How did the order get placed? | Programmatic trading |
The two are independent, and both combinations exist:
- Quant, not programmatic — a model ranks stocks every Sunday, you place the orders by hand on Monday
- Programmatic, not quant — a standing instruction: “sell if it falls 5% from here”. No model, no signal, still a program
Calling one the other is how a product gets to sound more sophisticated than it is. “We use programmatic trading” can mean nothing more than an automated order type.
What the regulator means by it
In China the umbrella term in the rulebook is programmatic trading, not “quant”. The CSRC’s 证券市场程序化交易管理规定（试行） was published on 2024-05-15 and took effect on 2024-10-08, and its text explicitly glosses the subject as “programmatic trading (what the market usually calls quantitative trading)”. The futures-market equivalent took effect on 2025-10-09, and the exchanges’ implementing rules on 2025-07-07.
So in a regulatory sentence, the two words are used as one thing. In a technical sentence, they are not. Know which sentence you are in.
Why it matters for AI quant
When someone says “we do quantitative trading”, ask which layer they automated. If the answer is only the clicking, they have built an execution tool — which is useful, and is not an edge.
The standards take the same position: what makes a claim checkable is the decision rule and its failure condition, not the fact that a machine was involved.
