Why every prop desk needs a state machine
Risk officers spend most of their day in two states: enforcing rules manually, or wishing they were. A small piece of well-designed software removes both.
The workload audit
We surveyed eighteen prop desks across four jurisdictions last quarter. The senior risk officers' time broke down, roughly, like this: 60% mechanical enforcement (watching positions, intervening when limits are approached), 25% incident response, 15% policy work and reporting.
The 60% is what should not exist. Mechanical enforcement is, by definition, mechanical. A human in the loop does not improve the decision; it only adds latency and human error.
What the state machine replaces
ACIE replaces the 60%. A risk officer configures the policy, drawdown caps, position-size limits, cooldown windows, once, and the state machine enforces it on every order. The officer's time moves to incident response and policy work, both of which actually benefit from human judgment.
The job of the risk officer is to design and review policy, not to enforce it order by order.
Why most desks haven't done this already
The honest answer is that purpose-built governance infrastructure has not existed. Most desks have stitched together broker-level limits, spreadsheet-based daily checks, and a Slack channel where the risk officer manually approves anything unusual. Each piece works in isolation; together they leak.
ACIE replaces the stitching with a single layer that sees every order across every venue. That is the difference.
