Signed Signals — Non-Custodial EST. 2026 · VOL. I
Factor-ranked equities · traded from your own machine

Your broker.
Your keys.
Zero custody.

Rebalx publishes a signed strategy signal very rarely. An app running on your machine — keeper of the only copy of your trade-only API key — verifies the signature and places the orders in your brokerage account. The key never leaves your computer; neither your money nor your credentials ever pass through our hands.

§ 01

Boring factors, on purpose.

No sentiment scraped off social media, no tea leaves. A composite score built from factors the academic literature has priced for decades — blended, ranked, and traded sparingly. The exact recipe is part of the subscription, not the brochure.

Value
Cheap relative to fundamentals. What you pay for each dollar of the business.
FACTOR 01
Momentum
Relative strength over the trailing window. Trends persist longer than they should.
FACTOR 02
Quality
Profitability and balance-sheet discipline. Survivors compound; stories don't.
FACTOR 03
One composite ranking
Names that qualify are bought; names that fall away are sold. Almost nothing happens in between — and that is the point.

Selection was made on risk-adjusted return, not raw total return — the momentum-only variant earned more but with twice the drawdown. The chosen composite carries a Deflated Sharpe Ratio of 0.998, correcting for the fact that eight variants were tried; above 0.95 indicates the result is unlikely to be a lucky draw. These are backtested figures, not live performance, and past results do not guarantee future returns.

§ 03

The custody ledger.

Most services ask for trust first and explain later. We'd rather state plainly what sits on each side of the line.

Matter
Rebalx
You
Your funds
Never held, never seen
Sit at your broker throughout
Your API key
Never received — it exists only in your keychain
Issued by you, deleted by you
Withdrawal permission
Moot — we hold nothing, and the app refuses keys that carry it
Switched off by you, at the broker itself
Order execution
Nobody at Rebalx touches an order — your local app places every one
Watched live in your broker's own app

A signed file arrives very rarely. Your app verifies the signature before a single order moves — forged, stale, or tampered, and it does nothing at all.

§ 04

Set once. Runs without you.

(i)

Issue a trade-only key

Create an API key at your broker with withdrawals switched off at the source. Paste it into the Rebalx app on your computer — it is sealed into your operating system's keychain and never leaves the device. A key carrying broader rights is refused on the spot.

(ii)

Then it runs without you

A resident process waits for the next signed artifact and rebalances your account when it lands. Asleep, offline, rebooted — whatever was missed executes the moment your machine wakes. One install, then nothing to babysit.

(iii)

Every move stays yours

Each fill lands in your regular broker app the moment it happens. Leave whenever you want — delete the key and there is nothing left to revoke, because nothing was ever stored anywhere else. Your money never spends a night anywhere else.

§ 05

One monthly fee. Not a share of your gains.

₩10,000/ month

One flat monthly subscription — the same whether your account is $1,000 or $1M. Cancel any time; access continues until the end of the paid period. If the strategy repeats its backtest, the fee is a rounding error. The table above is the only promise we make.

  • A local app that trades your brokerage account — under your own key
  • Trade-only enforced — withdrawal-capable keys refused at setup
  • Every signal cryptographically signed and verified before any order moves
  • The complete methodology, disclosed to members in full

§ 06

Questions, answered directly.

Do you ever have access to my money?

No — structurally, not just by policy. Your API key is created at your broker and lives in your own machine's keychain; it is never uploaded or transmitted anywhere. We have no credentials to misuse and no assets to hold — funds sit at your broker start to finish.

So where does my API key go?

Nowhere. Into your operating system's keychain — on your computer, encrypted at rest, readable only by the app. On setup the app reads your key's permissions back from the broker to confirm withdrawals are switched off; a key that can cash out is refused outright. Want us gone? Delete the key. There is nothing server-side to revoke, because there was never anything server-side.

Which brokers are supported?

Crypto-linked equity venues first (OKX, Binance), followed by regional brokers — Korea, Thailand, and Singapore (Interactive Brokers). Each broker is one adapter; the account interface was designed for them to be added independently.

How often will it trade?

Deliberately rare — every extra trade is a cost, often a tax, and the evidence behind the ranking works on months rather than minutes. Members alone get the exact frequency and dates; between turns, doing nothing is the strategy.

Is this investment advice?

Rebalx sells software and signed signals. The app on your computer directly executes the fixed, rules-based strategy you selected and subscribed to in your own brokerage account, using a key that never leaves your machine. Rebalx does not hold customer assets or provide personalized investment advice, and does not decide or place any orders on your behalf.

The market opens every day.
You never have to touch it.
