Controls & Evidence — deterministic controls, defensible decisions

THE CHECKS

Pre-trade controls, every trade
Low latency. Try it below

Send a trade in any format — broker shorthand, a voice transcript, Bloomberg/Reuters codes or structured API. Neith normalises it, runs its deterministic controls at once, and explains anything unusual in plain English.

In production Neith reads trades automatically at the point of capture — no copy-pasting. This box illustrates the shape of what Neith flags; real checks run server-side against your desk's thresholds.

PRE-TRADE CONTROL CATEGORIES

Every flag is explained in plain English and written to the record — advisory only, so the trader or broker always makes the final call.

THE RECORD

Every action recorded
One button to the report

Every advisory, flag, human response and threshold change is written to an append-only log the moment it happens — then exported as a regulator-ready pack in one click.

A dismissed pop-up alert once turned a mis-keyed order into a $444bn basket — £61.6m in FCA and PRA penalties. Nothing recorded that the alert had been ignored.[2]

WHAT NEITH RECORDS — EVERY TIME

EVENT

Every trade seenClear or flagged, no exceptions. Fully referenced and timestamped.

CHECKS

Every control that firedEach control, with the rule and threshold it evaluated against.

REASON

Why it was flaggedThe plain-English advisory shown to the trader, stored verbatim with the rule that produced it.

HUMAN

What the human did nextWho saw the flag, what they decided, and when. Evidence of a judgement made — which is what SM&CR attribution protects.

CONFIG

Every threshold changeWho changed which limit, when, from what to what. Your configuration history is itself an audit record.

GAPS

Every gap in coverageIf Neith was unreachable, the window is logged explicitly. A silent gap is never presented as a clean period.

Append-only and tamper-evident. Nothing is edited, overwritten or deleted — not by your team, not by ours — and any tampering is detectable.

COMPLIANCE REPORT — ONE CLICK

Pick a period. Press the button. You get a complete, regulator-ready pack — no data pull, no spreadsheet assembly, no ticket to IT.

The same record shows which rules fire, which get waved through, and which are overridden so often they are noise — so you can tell a miscalibrated control from a delinquent desk.
