Agentic trading software you own and run
Two very different things share one name
Search for agentic trading software and you will find two products wearing the same label. The first is a feature inside a brokerage. You open an account there, switch on an agent, and it trades within that firm's walls. The second is software you license, install and run yourself, pointed at whatever brokerage account you already have.
They are not competing versions of the same thing. They differ on who holds the software, who holds the account, and who can change either one.
What each model actually gives you
What a brokerage service gives you
Convenience, mostly, and it is real. There is nothing to install, nothing to keep running, and the broker has already solved the connection between the agent and the account. For someone who wants to try the idea, it is the shortest path.
What you give up is control of the arrangement. The agent runs on the broker's terms, on the broker's schedule, inside the broker's account. If the feature changes, is repriced, is restricted to certain assets, or is withdrawn, that is not a negotiation. Your strategy lives inside somebody else's product decision.
What licensed software gives you
The software sits on a machine you control and connects to a brokerage account that is already yours. Nobody is between you and your broker. If the vendor disappears, the software you have keeps running, and with a source licence you can keep maintaining it.
It also means the software can be more opinionated than a broker feature is allowed to be. A brokerage has to serve every customer and stay inside its own compliance posture. Licensed software can enforce a strict discipline, refuse trades aggressively, and stop for the day, because it only has to answer to the person who licensed it.
Your account, your keys, your machine
The practical test is where your credentials live. In a brokerage service the question does not arise, because the broker is the service. In licensed software it matters a great deal, and the right answer is that your API keys stay on your machine, in the operating system's own credential store, and are never transmitted to the vendor.
The same goes for your trading record. A local database on your own machine means your positions, decisions and results are not sitting in a vendor's cloud, and there is no third party to breach.
When a service is the better answer
If you want to trade a small amount, are curious rather than committed, and would rather not run software, use the brokerage feature. It is cheaper and faster and there is no shame in it.
Licensed software earns its cost when you intend to run something continuously, when you need the record for your own reporting, or when you cannot accept that a third party can change the rules underneath you.
What running it yourself asks of you
Questions to ask before you commit
Does it use my existing brokerage account, or does it require a new one? Where are my credentials stored? Where does my trading history live, and can I export it? What happens if you go out of business? Can I run it against a paper account first, and for how long? Is the source available under any tier, and what does that licence permit?
The answers separate a licence from a subscription with extra steps.
What running it yourself actually asks of you
A machine that stays awake and connected, and a willingness to look at it. Licensed software is not maintenance free. It needs a computer that does not sleep, an internet connection that mostly stays up, and someone who notices if it has stopped.
None of that is demanding, but it is real, and it is the honest trade against a brokerage service where the broker handles all of it. If nobody in your setup is going to check on a machine, buy the service.
The question of who can change the rules
With a service, the terms can change and you will be told afterwards. Assets can be restricted, limits imposed, the feature paused. With a licence, the software you have keeps behaving the way it behaved yesterday.
For someone experimenting, that difference is academic. For someone who has built a routine around it, or who is answerable to somebody else for the results, it is most of the decision.
Making the decision
What the record is worth
Software that has been running for a year holds something a fresh installation does not: a history of its own decisions and what came of them. That record is the reason switching costs are higher here than the installation effort suggests.
It is also the reason a local datastore matters. If the record lives with a vendor, leaving means leaving it behind.
A reasonable way to decide
Run the thing on paper for a month before paying for anything beyond an evaluation. Judge it on how it behaves rather than what it earns, because a month is far too short to say anything about earnings and quite long enough to reveal whether the software is careful.
Common questions
- Do I need a new brokerage account?
- No. Licensed software connects to an account you already hold. That is the main practical difference from a brokerage feature, where the account and the software are the same product.
- What happens if the vendor stops trading?
- With a licence to run, the software you have keeps working. With a source licence it also stays maintainable. Without either, its lifespan is the vendor's lifespan.
- Where are my API keys stored?
- In the operating system's own credential store on your machine. They should never sit in a configuration file and never be transmitted to the vendor.
