§ 01

Doing it yourself is a chore. Handing it over is a risk.

Do it yourself

Endless homework

Research, spreadsheets, and the discipline to rebalance on schedule — every time, without flinching. Most people skip it the moment markets get loud.

Hand it over

Someone else holds it

Your money sits with someone else, often for a percentage of your assets every year, and you find out what they did after the fact.

Rebalx

Rules, run by you

A rules-based strategy, executed by an app on your own computer, in your own account. A flat monthly fee. Watch every trade, stop any time.

§ 02

Three steps. Then it runs on its own.

(i)

Subscribe and install

Pick the plan, download the app for Mac or Windows, and sign in with your Rebalx account.

(ii)

Connect a trade-only key

Create an API key at your exchange with withdrawals switched off and paste it into the app. It is stored in your computer's keychain and never sent to us. Keys that can withdraw are refused. (Exchange key setup guide)

(iii)

That's it

The app waits for each new signed signal, checks it, and rebalances your account. Asleep or offline when it arrived? It catches up when your computer wakes. Every trade shows up in your broker's own app.

§ 03

Proven, not trending.

We don't trade on hype or gut feel. A handful of factors, proven over decades, score every stock and roll up into one composite score that ranks the list — and we trade only on the rare occasion that ranking changes.

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, and past results do not guarantee future returns.

§ 05

Your money never passes through us.

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.

§ 06

One monthly fee. Not a share of your gains.

$9.90/ 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.

Illustration · typical wealth management vs Rebalx · a $50,000 account over one year
Typical wealth management (1% of assets)$500.00
Rebalx ($9.90 × 12)$118.80

An illustration based on the "1% of assets" fee structure common in wealth management, not a quote from any specific provider. A percentage fee grows with your balance; Rebalx stays $9.90 regardless.

§ 07

Frequently asked questions

What do I need to get started?

A Mac (Apple Silicon) or Windows PC that you keep on regularly, an exchange API key, and the Rebalx app — that's all you need. Setup takes a few minutes.

Can I cancel any time?

Yes. Cancel from your account page; access continues until the end of the paid period. Your holdings stay in your exchange account either way — delete the key and the app stops trading.

Do you ever have access to my money?

No — structurally, not just by policy. Your API key is created at your exchange 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 exchange start to finish.

So where does my API key go?

Only on your own computer. It's stored encrypted, and only the app can read it. Keys with withdrawal permission are refused right at registration. Want out? Just delete the key — there's nothing on our servers to begin with.

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 exchange 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.

Let the rules do the work.
