Automated trading that refuses to let you fool yourself.
Most trading software sells a pretty backtest. Dawnstar is built to do the opposite — bake professional anti-overfitting rigor into the core and show you, plainly, when an “edge” isn’t real. Paper-by-default. Non-custodial. Yours to run.
Give independent traders institutional-grade honesty — the tools to tell a real edge from noise, and the discipline to act only on the difference.
The trading-software industry runs on hope: an up-and-to-the-right equity curve, a number with no error bars, a strategy that quietly falls apart the moment real money touches it. Dawnstar Development & Publishing exists to build the counterweight — software that measures its own uncertainty out loud, defaults to safe, and never asks you to trust a claim it can’t show. We would rather tell you “this isn’t real” than sell you a dream.
Six promises we build into the code — not just the copy.
These aren’t a marketing stance we can quietly walk back. Each one is enforced by how the software is architected, and every claim on this page is one we can demonstrate.
We never overstate an edge
Dawnstar surfaces the Deflated Sharpe Ratio, the Probability of Backtest Overfitting, walk-forward efficiency and Monte-Carlo bands on every result — even when the honest answer is “this is noise dressed as edge.” The whole system currently has no demonstrated edge, and we say so everywhere it matters.
Paper-trading by default
Out of the box it trades a simulated account. Real money requires two independent, deliberate gates plus your own live broker keys — there is no single switch that flips everything to real money by accident.
Non-custodial, always
Dawnstar is not a wallet, bank, or money transmitter. It never holds, receives, or moves your funds. Your money stays at the regulated brokers you connect; Dawnstar only sends orders through their official APIs with keys you control and can revoke.
The AI can only add caution
The built-in AI is a paid skeptic. Structurally, it cannot touch the trade path — it produces language, never decisions — and it refuses personalized advice or price predictions. It only ever argues for more caution, never less.
Your keys stay yours
Broker credentials are sealed in a local encrypted vault (Argon2id + AES-256-GCM, bound to your Windows account) and never leave your machine. We have no server that could see them, because there is no server.
Not financial advice
Dawnstar is a tool, not an adviser. Nothing it or this site shows is a recommendation to buy or sell anything, and past or backtested results never guarantee future results. You are responsible for every order it places on your behalf.
A complete, honest automated-trading workstation for your own desktop.
One native Windows app. It scores strategies with real statistics, connects to your brokers, and can run trading cycles on a schedule — with every safeguard on by default.
The Rigor Engine
The heart of Dawnstar. Probabilistic & Deflated Sharpe Ratios (Bailey & López de Prado), an empirical Probability of Backtest Overfitting via CSCV, walk-forward efficiency, and Monte-Carlo confidence bands — computed by the same C++ engine that trades live, so results match what actually runs.
The AI Skeptic & chat
An advisory-only assistant that critiques your backtests for overfitting and explains the statistics in plain English. It works fully offline as a heuristic, or with your own API key for a written adversarial review. It can only ever lower your confidence — never green-light a trade.
Encrypted vault
Broker keys are stretched with Argon2id and sealed with AES-256-GCM, DPAPI-bound to your Windows account and wiped from memory on lock or idle. One-click backup, and an honest reminder: there is no password recovery, by design.
Broker connections
US equities via Alpaca and forex via OANDA, through their official APIs — paper/practice by default. Coinbase is on the roadmap. We’re candid about limits too: there’s no supported Robinhood integration, because it would mean violating their terms.
Risk-first execution
Position and exposure caps, a daily-loss halt, a pattern-day-trader guard, an always-available kill switch, and idempotent order handling so a network blip can never double-fire a trade. Exits and de-risking are never blocked.
Backtest = live, one engine
The same code path runs your backtest and your live orders, so there’s no “it worked in the sim” gap. Every shipped binary is inventoried with a published SHA-256, and the build is open and documented — verify what you run.
Deliberately slow, in the order that keeps you safe.
Dawnstar makes going live take real, conscious steps — because the point isn’t to trade fast, it’s to trade only what you’ve actually validated.
Backtest with rigor
Run your strategy and read the scorecard like an allocator — if the Deflated Sharpe and PBO say it’s a curve-fit, stop here.
No moneyPaper-trade for weeks
Watch it run live-shaped on a simulated account. This is the point, not a formality — most strategies fail here.
SimulatedArm gate one
Deliberately enable live mode. Nothing happens yet — it’s one of two independent locks, each requiring a fresh confirmation.
Gate 1 of 2Arm gate two + live keys
Acknowledge the risk file and supply live broker keys. Only now can real orders be placed — with every risk cap still on.

Dawnstar Development & Publishing
We’re an independent software studio building tools for people who’d rather see the truth than a sales pitch. Dawnstar Trading is our flagship — but the standard behind it is the whole company: measure uncertainty out loud, default to safe, hold user data at arm’s length, and never ship a claim we can’t demonstrate.
“Dawnstar” is the morning star — the light that shows up at the edge of dawn. It’s the promise we build toward: clarity where the rest of the category sells fog.
Will this make me money?
We won’t pretend to know. Dawnstar has no demonstrated edge — it’s a tool for testing and running strategies honestly, not a promise of profit. Trading carries a real risk of loss. Anyone who guarantees returns is the exact thing this product exists to warn you about.
Do you ever hold or move my money?
Never. Dawnstar is non-custodial — not a wallet or money transmitter. Your funds stay at the regulated brokers you connect. It only sends orders through their official APIs using keys you control and can revoke at any time.
Why does Windows warn about the download?
The build isn’t yet signed with a publicly-trusted certificate, so SmartScreen flags an “unknown publisher.” That’s normal for an independent pre-certificate release and doesn’t mean the file is unsafe. Confirm it wasn’t altered by checking its SHA-256 against the value on the release page — in PowerShell: Get-FileHash .\Dawnstar-Setup.exe -Algorithm SHA256 — then choose “More info → Run anyway.” A publicly-trusted certificate is on our roadmap.
Is my data private?
Yes. There is no Dawnstar server. Everything — your keys, strategies, and trade history — lives on your own machine in an encrypted vault. We can’t see it because it never reaches us.
Which brokers are supported?
US equities through Alpaca and forex through OANDA, paper/practice by default. Coinbase is on the roadmap. Robinhood is not supported, because there’s no official API that would let us do it within their terms — and we won’t pretend otherwise.
Is this financial advice?
No. Dawnstar is software, not an investment adviser, broker-dealer, or fiduciary. Nothing it outputs is a recommendation, and you’re responsible for every order it places. Read the full disclaimer before connecting a broker.
