Self-hosted trading software
What self hosted trading software removes
Almost every trading product is a service. Your broker keys live in someone else's database, your positions are visible to their staff, and the logic deciding your trades runs on machines you cannot inspect. Self-hosting removes that entire category of exposure by not creating it: the software runs on your hardware, holds your keys locally, and talks to your broker directly.
What stops being your problem
Vendor breach
A breach at a hosted provider is a breach of every customer's brokerage credentials at once. If your keys were never on their systems, their incident is news rather than an emergency.
Vendor outage
Hosted logic means their downtime is your downtime, at whatever moment it happens. Self-hosted, our availability has no bearing on whether your desk trades.
Vendor solvency
Companies get acquired and shut down. Licensed software you already hold keeps running; updates stop, which is the honest trade, but the desk does not go dark.
Silent behavioural change
On a hosted service the operator can change how capital is deployed without asking. Self-hosted, nothing changes unless you apply an update.
Where the data actually sits
Credentials in the operating system keychain
Broker API keys go into the macOS Keychain, encrypted at rest by the operating system and never written to a configuration file. There is no vendor copy because there is no vendor server.
Market and account data stay local
Storage is a local database and research store on your machine. Nothing leaves it. For anyone whose holdings map to identifiable people, that removes a question rather than managing it.
Outbound only, to the parties you chose
The desk talks outbound to your broker, to regulators and to public data. It is not reachable from the network and there is nothing listening for inbound connections.
What self-hosting asks of you instead
A machine that stays on
One dedicated machine, a Mac or a Windows PC, always on, not used for anything else, with sleep and automatic updates disabled. This is the real cost of self-hosting and it is small.
Responsibility for the environment
Nobody else is watching the machine. Protection resting at the broker is what makes that survivable, because a machine being off does not leave a position unmanaged.
Your own judgment about when to update
You control updates, which means you also own the decision to apply them. That is more control and more responsibility at the same time.
Who self-hosting suits
Anyone who will be asked to answer for it
Allocators, trustees and compliance functions all ask where data sits and who can change behaviour. Self-hosted answers both without qualification, which is why funds and family offices tend to end up here.
Anyone whose holdings identify a person
Family office and private investor positions map to real people in a way institutional positions do not. Not creating the exposure is stronger than managing it.
Anyone who needs continuity guarantees
If your trading cannot stop because a supplier had an incident or an acquisition, hosted logic is the wrong architecture regardless of the vendor's reliability record.
Who it does not suit
If you want zero infrastructure responsibility and are comfortable with the trade, a hosted service is genuinely easier and we would not pretend otherwise.
Setting the machine up properly
Disable the things that interrupt
Sleep, automatic operating system updates and anything throwing a modal dialog are all hazards on a machine running unattended. Turn them off deliberately rather than discovering them.
Wire it, do not trust wifi
A dropped connection at the wrong moment is avoidable. Ethernet costs nothing and removes a class of problem.
Administer it remotely
Once configured you rarely need to sit at it. Screen sharing from your normal machine keeps the trading machine isolated from everything else you do.
Keep it doing one job
The single most effective thing you can do is refuse to use that machine for anything else.
What self-hosted does not mean
It does not mean unsupported
Licensed does not mean you are on your own. Support that reaches a person is part of what the license buys, and it matters more when nobody else is watching the machine.
It does not mean building anything
You install an application. Self-hosting here means the software runs on your hardware, not that you assemble a system from parts.
It does not mean no internet
The desk talks outbound to your broker and to public data. What it does not do is accept inbound connections or send your positions anywhere.
Common questions
- What is self-hosted trading software?
- Software you install and run on your own hardware, holding your own broker credentials locally and connecting directly to your brokerage, rather than a service where the trading logic runs on a vendor's servers. The practical difference is that the vendor's breach, outage and solvency stop being risks to your account.
- Is self-hosted trading software more secure?
- It removes a category of risk rather than managing it. Your broker API keys never sit in a vendor database, so a breach at the vendor cannot expose them, and your positions are not visible to their staff. In exchange you become responsible for the machine it runs on, which is why protective orders resting at the broker matter.
- What happens to self-hosted software if the vendor goes out of business?
- It keeps running, because it is already on your machine and does not check in with anyone to work. Updates stop, which is the genuine trade-off, and it is the main reason firms take a source license. With a hosted service the answer is that your trading stops when the company does.
