Ground rules for your brokerage link.

  • Guided reconnect when your broker needs fresh authorization.

  • $5/week after your first successful trade; no card to start; cancel anytime from Settings.

Proof, not promises

We ran it by hand. Then we automated it.

How to read this chart

This chart shows dollars made, grouped by the month each trade closed. By hand through April 2026, then with OneArbitrage from May 2026. The vertical line marks that switch. This reflects how we ran our own account, not a promise of what you will earn.

How it works.

From zero to “it’s running” in four moves.

  1. Get the app

    Download OneArbitrage on the App Store or Google Play, then sign in or create your account there.

  2. Connect your brokerage

    Sign in on Robinhood's site. We never see your password. No card required.

  3. Your first successful trade is free

    Trades run in the background. The first winner costs you nothing.

  4. Keep earning for $5/week

    The app asks once after that first win. Pass and new buys pause while open positions still close.

Why members say yes

Three reasons people say yes.

Less jargon. More of what actually matters: your money, your time, and straight answers in the product.

  • Three years tested first

    RSA on a linked brokerage: years of hands-on runs, then the same workflow automated. The cumulative log is charted below.

  • Set it up once, then step back

    Link your brokerage and finish a short setup in plain English. After that, RSA runs in the background, so you spend less time watching deadlines, not more.

  • You keep what you earn

    One flat $5/week through Stripe after your first successful trade; OneArbitrage never takes a cut of your gains.

Reverse stock split arbitrage, in plain English

How reverse stock split arbitrage works.

1 share before the split, a fraction after, then a round-up when allowed. OneArbitrage automates that on the brokerage accounts you connect.

  1. Buy 1 Share

    You buy 1 share of a stock facing a 1-for-25 reverse split.

    Investment

    -$0.35

  2. The Split Happens

    Your 1 share becomes a fraction when the split executes. A round-up (when the issuer allows it) turns that fraction into 1 full share. The quote moves to $8.75 ($0.35 × 25).

    Position

    1. 1 share
    2. Reverse split
      0.04 share
    3. Round up
      1 share

  3. Sell For Profit

    After the round-up posts, you hold 1 full share. OneArbitrage sells it in your linked account to lock in the gain.

    Profit

    +$8.40

    2,400% return on 1 share
