This question matters more than most compliance conversations because it sits at the intersection of two genuinely complex domains — financial services law and automated systems architecture. Getting either one wrong is expensive. Getting both wrong simultaneously is the kind of thing that ends careers and triggers Section 912A breach notices before breakfast.

The direct answer is this: an API-based trade signal agreement must be structured so the fund manager retains demonstrable accountability for every execution decision, even when that decision is triggered algorithmically. ASIC's best interests duty under RG 175 doesn't pause because a webhook fired. The obligation follows the licence, not the latency.

CONCEPTThe fund manager's AFSL obligations apply to every trade signal received via API — automated delivery doesn't transfer legal accountability to the signal provider.
WARNINGDrafting an API agreement that treats signal ingestion as purely technical — not advisory — is the most common and most costly structural mistake Australian fund managers make.
KEY IDEABest interests duty requires a documented decision framework sitting between signal receipt and order execution — a human or auditable rule-set must own that gap.

Think of it like a sous chef arrangement. The signal provider is the head chef calling out dishes from the pass. But if the sous chef — the fund manager — plates something that poisons a diner, the defence "the head chef told me to" won't satisfy the health inspector. The sous chef has independent professional obligations. ASIC is very much the health inspector in this analogy, and they've read the menu.

In practical terms, the agreement itself needs several structural components. First, it must clearly classify whether the signal provider holds an AFSL or is operating under a carve-out — this determines whether their output constitutes financial product advice under the Corporations Act 2001. Second, the agreement should specify a documented filter protocol: the fund manager's process for evaluating each signal against the client's Statement of Advice, investment mandate, and current portfolio composition before any order is placed. Third, liability allocation clauses need careful drafting — courts and ASIC will look past boilerplate indemnities if the operational reality shows the fund manager was rubber-stamping signals without genuine oversight. For deeper grounding on the regulatory mechanics, fiduciary duty principles explain why accountability can't simply be contracted away, while the AFSL framework on Wikipedia outlines the licence obligations that underpin RG 175. The technical side of how these systems transmit instructions is well covered under application programming interfaces, which helps when briefing legal counsel who may be less familiar with the architecture.

The practical takeaway is simple: print the phrase "the API is a pipe, not a defence" and pin it above whoever reviews your signal agreements. Then build your compliance layer accordingly.
