Trading desk automation
Automating a desk is an operations problem
At one seat, automating a desk is a software choice. Across a floor it becomes an operations question: who can change what capital does, how that change is approved, how results are attributed, and what happens when the person who set it up leaves. Almost none of that is about strategy.
Firms that start from the strategy and retrofit the operations end up with something they cannot defend to a risk officer, an allocator or an auditor.
Which desk functions automate cleanly?
Continuous monitoring
Watching more instruments than a person can hold, at one standard, without fatigue. The clearest and least contested win.
Refusal and its record
A system that logs every declined candidate with a reason produces evidence a human desk never keeps, because nobody writes down the trades they did not take. That record is what makes the rest auditable.
Reconciliation and reporting
Rebuilding realised results from the broker of record rather than from intent. Mechanical, unending, and exactly what software should own.
Execution cost measurement
Measured from the desk's own fills and priced into later decisions, rather than discovered at the end of a quarter. At desk scale this is a line item that decides profitability.
What must not sit inside the software?
The limits that cap loss
A per-trader or per-book loss limit has to survive the trading application crashing or being restarted. Limits enforced where the firm can see and change them, with the software operating inside them rather than owning them.
The override
Someone on the risk desk must be able to flatten or halt without waiting for a trader, a vendor or a process restart. An override that requires a healthy application is not an override. Test it at speed before funding anything.
The record of who changed what
If any part of the software tunes its own behaviour, that is a change to a production system. What changed, when, on what evidence, and what would reverse it.
How does attribution work across seats?
Per seat, reconciled to the firm's books
When several autonomous seats share firm capital, attribution stops being a reporting nicety and becomes the basis of the payout. It has to reconcile to the broker's record rather than to what the software intended.
Configuration that outlives the person
When someone leaves, the firm keeps the seat, the record and the configuration. A licence tied to an individual creates an administrative problem at every turnover.
Change control across a floor
When the software updates it should not update some seats and not others by accident. Establish how a change rolls, who approves it, and whether a seat can be held back.
What does diligence ask about it?
Who can change how capital is deployed
And whether that requires a second approval and is logged. A vendor able to push behavioural changes without your sign-off is a finding that is hard to explain away.
Whether you can reconstruct a decision
Not the fills, which the prime broker has. The reasoning, including the declines, so that a bad process can be told apart from bad luck after the fact.
What happens if the vendor stops trading
If the system decides on a vendor's infrastructure, the honest answer is that the desk stops. If it decides on your own machines with your own keys, and you hold source, the answer is materially better.
Common questions
- What does trading desk automation actually cover?
- At firm scale it covers continuous monitoring, recording every decision including refusals, reconciliation to the broker of record, and measuring execution cost and pricing it into later decisions. What it should not cover is the limits that cap loss or the risk desk override, both of which have to sit outside the software.
- What should stay outside the trading software?
- The loss limits and the override. A per-trader limit has to survive the application crashing, and a risk desk must be able to flatten or halt without depending on the trading software being responsive. If either lives only inside the software, it is a suggestion rather than a control.
- How do you attribute results across automated seats?
- The decision record has to be per seat and reconcile to the firm's own books rather than to what the software intended. At a prop firm attribution is the basis of the payout, so a discrepancy between the software's view and the broker's record becomes a dispute with a trader rather than a reporting nuisance.
- How do you change-control software that changes itself?
- Treat any self-tuning as a change to a production system: what changed, when, on what evidence, and what would reverse it. Ordinary change control assumes changes arrive as releases, so a system that adapts from its own results needs a path that is not a code deployment.
