Deploy paper¶
Paper trading runs strategies through the daemon against the in-process PaperBroker — no network calls, no real money, deterministic fills. It's the right environment for:
- End-to-end smoke testing before going live
- Long soak tests on a strategy you've backtested
- Multi-strategy resource and behavior validation
Prerequisites¶
qktinstalled and onPATH(see Quickstart step 1)
Run a single strategy¶
# Start the daemon. The control plane binds an ephemeral port on 127.0.0.1.
qkt daemon &
qkt deploy momentum.qkt --as momentum
qkt list
qkt status momentum
qkt logs momentum --follow
Stop one strategy without stopping the daemon:
Stop the whole daemon:
Run many strategies at once¶
Drop .qkt files into a directory, start the daemon with --load-dir, every file auto-deploys:
This is the same convention the Docker compose stack uses (it mounts ./strategies at /strategies inside the container).
Inspect logs¶
Per-strategy log files live at ${QKT_STATE_DIR}/logs/<name>.log. The default state dir is ~/.local/state/qkt/.
The CLI streams them via the daemon's HTTP control plane:
qkt logs momentum --lines 200
qkt logs momentum --follow
qkt logs momentum --since 2026-05-10T10:00:00Z
Logs are tagged with [strategy] so when multiple strategies log to stdout you can tell them apart. See logging for the MDC keys and pattern conventions.
What you can't do on paper¶
The paper broker doesn't simulate:
- Spread or slippage
- Partial fills
- Network latency
- Broker-side reconnection
- Position drift across restarts
For any of those, deploy to MT5 against a demo account (Deploy MT5).
