Frequently Asked Questions

Quick answers about RSA, billing, brokerage linking, and your account.

Product & getting started

What is OneArbitrage?▼

OneArbitrage is subscription software (SaaS) that helps you run our reverse stock split arbitrage (RSA) on Robinhood accounts you link, when you choose to use it.

We are not a broker-dealer. Your account and assets remain at your brokerage. See our Terms for how the service is described.

Who is eligible to use OneArbitrage?▼
Today OneArbitrage requires Robinhood. You need to be able to open and maintain a Robinhood account. Robinhood usually requires identity verification (for example, SSN or TIN) and a verifiable address; exact rules are set by Robinhood, not OneArbitrage.
How do I create an account?▼
Download the OneArbitrage app from the App Store or Google Play. New accounts and sign-in happen in the app.
Do I need to install an app?▼
Yes. OneArbitrage now runs entirely in the iOS and Android apps. Download it from the App Store or Google Play.

Sign-in & account

How do I reset my password?▼
Password reset for the web dashboard is no longer available. Download the mobile app and recover your account there.
How do I delete my account?▼

In the mobile app, open Settings, scroll to Delete account, type DELETE MY ACCOUNT, and confirm. We remove your login, cancel Stripe billing, and delete product data we store for you, subject to the Privacy Policy and any law we must follow. If you subscribed through the App Store, cancel that subscription in your Apple ID settings; deleting your OneArbitrage account does not stop App Store charges. This does not close brokerage accounts you hold at Robinhood or other brokers. You can also email support@onearbitrage.com if you need help.

Will you delete an account I never used?▼

If you create an account, never subscribe, and do not use the app, we may email you twice with the date we will delete it. Signing in before that date keeps the account. We leave the account in place if you have ever subscribed, if you still have an open position, if you already completed the free first trade, or if a referral payout is still unfinished. Deletion removes your OneArbitrage login and the personal data we hold. Your Robinhood account stays open. If you had linked Robinhood, a later OneArbitrage account that links the same Robinhood identity is treated as if the free first trade was already used. See our Privacy Policy and Terms.

Brokerage & RSA

What is reverse stock split arbitrage (RSA) at OneArbitrage?▼

RSA is the automated workflow our subscription software runs on brokerage accounts you link and choose to use with the product. It is built around reverse stock split corporate actions: calendars, notices, broker cutoffs, cash in lieu of fractions, and other execution details that vary by issuer and firm.

We ran similar steps manually before we automated them in software. OneArbitrage does not pick securities for you or tailor recommendations to your situation. See the RSA guide for a plain-language explanation of how it works.

What is a reverse stock split?▼
A reverse split is a corporate action that reduces share count and raises the quoted price per share so that, before fees and taxes, the economics are usually intended to line up with what you held before. Issuers and brokers can treat fractional shares differently (including cash in lieu). For a longer walkthrough in our words, see the RSA guide. For independent background, see the SEC’s investor glossary entry on reverse stock splits.
Does every reverse split or similar corporate action produce a profit?▼
No. Outcomes depend on issuer documents, broker processing, timing, and taxes. Some actions pay cash in lieu of fractions; others may not play out the way traders hope. A subscription pays for software that automates reverse stock split arbitrage (RSA) on brokerage accounts you link and control.
Where can I read more from OneArbitrage?▼
Start with the evergreen RSA guide for how reverse stock splits and fractional handling relate to the product. Visit News for time-stamped announcements and updates.
How do I link my brokerage account?▼
In the app, connect Robinhood through the in-app connection flow. We never ask you to share brokerage passwords in email or chat. On the mobile app, reconnect may open Robinhood login in an in-app browser so we can receive session tokens Robinhood issues after you sign in (including a refresh token). We do not store your brokerage password.

Subscription & billing

How much does membership cost?▼
Your first successful trade is free. After that, membership is $5/week until you cancel; tax may apply. On Android, billing runs through Stripe. On iOS, it is an auto-renewable subscription through Apple, at the price shown in the App Store at purchase. No card is required to start.
How do I pay or update my payment method?▼
Subscriptions renew weekly until you cancel. If you pay through Stripe, manage your payment method in Settings in the mobile app. If you subscribed through Apple, manage or cancel in your Apple ID subscription settings.

Earnings & taxes

Can I compound my earnings in OneArbitrage?▼

Not inside the product today. OneArbitrage does not automatically sweep RSA cash into new positions for you. When a workflow step produces cash, it stays in your linked brokerage account’s cash balance until you trade, transfer, or withdraw using your broker’s tools.

We may add an optional way later to move idle cash into stocks or ETFs from the app. It is not available yet, we have not announced a date, and until then nothing in OneArbitrage replaces you choosing reinvestment at your broker.

Do I need to file or report taxes on RSA profits?▼
Yes. Profits that show up in your brokerage account are generally yours to report. Your broker supplies statements and official tax documents for activity on your account. Use your broker’s materials and, if needed, a qualified tax professional.

Referrals

How do referrals work?▼

Invite links often add ?ref= plus a code. We may keep it in session storage for that visit and record it once when your customer account is first provisioned; we do not change codes on accounts that already exist. For binding rules, see our Terms. Ask whoever invited you for a short summary.

How do referral commissions work?▼
For each person who uses your link and keeps a paid subscription, you earn 10% of qualifying payments (renewals included), subject to cleared invoices, program rules, Stripe processing, and cancellations. See our Terms and Referrals in the mobile app for your invite link, code, and reward status.
