Where this applies
United States, FINRA member broker-dealers. The rule says each associated person who is primarily responsible for the design, development or significant modification of an algorithmic trading strategy relating to equity, preferred or convertible debt securities, or responsible for the day-to-day supervision of such activities, shall be required to register as a Securities Trader; the regulatory notice adds that if a firm directs a third party to significantly modify a strategy, that direction must also be by a Securities Trader. It names who answers for a strategy; it does not govern how strategies are researched.
What this means
In the US, the person who designs a trading algorithm has to be a registered, named individual. However much of the research an AI does, someone registered answers for the strategy.
What it does not yet show
A US rule for broker-dealers in certain securities; it does not measure how strategies are built.
What you can check
Open FINRA Rule 1220 and find "primarily responsible for the design, development or significant modification of an algorithmic trading strategy".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
