Order reconciliation
Controls should be placed where they can actually prevent or detect the relevant failure. A visual warning does not enforce a quantity limit if another path can submit orders. Test all authorized entry paths.
Duplicate prevention
A stop or disable mechanism needs a precise scope: new entries, order submission, strategy evaluation or all activity. Disabling new entries does not necessarily cancel working orders or close positions. State these differences clearly.
Access management
Permission separation reduces accidental activation. Research tools, monitoring views and execution services can require different capabilities. A read-only audit should not obtain trading authority merely for convenience.
Audit records
Control state must survive or be reconciled after restart where required. A local toggle that resets to enabled can defeat an intended halt. Verify persisted state and startup behavior explicitly.
Worked example
An operator disables a strategy, but a previously submitted limit order remains working and later fills. The disable action stopped new signals, not existing venue instructions.
Try it yourself
Write a control description that distinguishes disabling new decisions from cancelling orders and closing positions.
Show the worked solution
Define each action separately, identify its permissions and acknowledgements, and show residual exposure after completion. Avoid a single reassuring label that conceals which states remain active.
Apply this to your course project
Run an incident drill with reconciliation and a documented shutdown.
Keep the calculation inputs, assumptions and decisions with your work. Practical exercises are self-reviewed; the scored knowledge checks assess the questions shown, not an independent certification of practical competence.
