What execution software can (and cannot) do: regulatory boundaries

Automated execution, portfolio management, and financial advice are different activities with different regulatory regimes. Where the line is drawn and why it matters.

Three activities, three regimes

In common language, "automated trading" covers everything, but from a regulatory standpoint activities are distinct. Financial advice - recommending instruments or trades to a specific client - is a reserved activity requiring authorization. Portfolio management - discretionary operation on client funds - is even more regulated. Instrumental execution of client-provided instructions is instead a technology activity.

Software that receives a client-selected signal, validates it against client-defined rules, and transmits it to the client's account at a client-selected broker is not advising or managing: it is executing. The difference is not cosmetic - it is what separates a technology provider from a financial intermediary.

Boundaries serious software does not cross

First: no fund custody. Money always stays in the client's account at their broker; the platform operates through trading credentials and cannot withdraw or move capital. Second: no proprietary signals framed as personalized recommendations. Third: no return promises - anyone promising returns on leveraged instruments is violating communication rules before even investment-service rules.

These boundaries protect the client, but they also protect the provider: a clear perimeter is what allows a service to exist sustainably over time.

What users should verify

From the user side, two checks always matter. First, the broker: it should be regulated in a serious jurisdiction, because funds reside there. Second, the execution platform: transparency on service limits, complete operation traceability, and credential encryption are baseline requirements.

As a rule, distrust anyone who deliberately blurs the three layers - signals, execution, management - because that confusion is almost always used to promise what cannot be delivered.
