DomeHFT documentation

Everything to install DomeHFT, activate your license, connect your brokers and go live — safely and fast.

Overview

DomeHFT is a native Windows high-frequency arbitrage terminal. It surfaces cross-venue edges, routes orders in microseconds through a hardened order manager, and enforces risk before anything reaches the market — all on your own machine, with your keys and data local.

Your DomeHFT account is managed from your DomeTerminal account (shared across both products). You log in to the app with that account; your device is bound on first login.

Requirements

Item	Requirement
OS	Windows 10 / 11 (64-bit)
Account	Active DomeHFT plan (Solo / Pro / Desk)
Network	Stable internet; low latency to your venues recommended
Brokers/feeds	Credentials for the venues you connect (FIX, cTrader, LMAX, MT5, etc.)

Install & activate

Buy a plan from the pricing page. Your license is provisioned automatically after payment.
Download the signed installer from your account (Downloads section). Verify the SHA-256 checksum shown next to it.
Run the installer. It's code-signed, so Windows shows a verified publisher.
Launch DomeHFT and log in with your DomeTerminal account (email + password).
On first login, your device is bound to your license automatically. You're ready to connect.

The installer and every build are code-signed and carry a signed integrity manifest. DomeHFT verifies itself on startup and refuses to run if a file was modified.

Connect brokers & feeds

Open Connections and add each venue with its native connector. DomeHFT keeps market-data feeds and trade routes as separate, typed connections.

Connector	Type	You provide
FIX 4.4	Feed + trade	host, port, SenderCompID, TargetCompID, credentials
cTrader	Trade (FIX)	SenderCompID, username, password
LMAX	Feed + trade (FIX)	FIX session credentials
MT5 bridge	Trade	an attached MT5 terminal + the DomeHFT EA
CME MDP3	L2 feed	market-data access

Some venues are feed-only or require a vendor SDK. DomeHFT always shows a connector's honest status — it never fakes a live trade path it can't execute.

Run strategies

DomeHFT ships strategy families for cross-venue work — triangular, statistical, basket and cross-broker arbitrage — plus portfolio orchestration. Open a strategy tab, pick the venues and symbols, set the parameters, and arm it.

Backtest first. Replay signals and sweep parameters on historical microstructure before going live.
Watch the desk. The arbitrage desk shows spreads, routing latency and fills in real time.

Risk & execution

Every order passes the pre-trade risk engine — configurable gates on exposure, notionals and velocity — before it leaves. A kill-switch halts new orders instantly. Fills are reconciled against the broker by a single order-management state machine, so there's one source of truth for every live path.

Devices & licensing

Your plan sets how many devices you can activate at once:

Plan	Devices
Solo	1
Pro	2
Desk	3

Each activation binds to that machine's hardware fingerprint. Switching computers? Open Devices in your account and reset a device to free a slot. Your license key is visible in your account for reference and support.

Security

Device-locked activation — won't run on a machine you didn't license.
Signed & integrity-verified — startup check blocks a tampered install.
Encrypted at rest — credentials and tokens protected with Windows DPAPI, never plain text.
Local by design — broker keys and data stay on your machine.

Updates

DomeHFT checks for new versions and notifies you when an update is available. Download the latest signed build from your account; your license and settings carry over.

FAQ

Do I need to type a serial?

No — you log in with your account and the device binds automatically. Your license key is shown in your account for records.

Can I move to a new PC?

Yes. Reset the old device from Devices in your account, then log in on the new machine.

Will it run on another PC if I copy the installer?

It installs, but it won't activate beyond your plan's device limit — activation is bound to your licensed machines.

Are my keys private?

Yes. DomeHFT runs locally; keys and data never leave your PC.
