Frequently asked questions

Short answers about Mos Terminal: what it is, how the hard stop and the day breaker work, API key safety, pricing and the invite-only beta.

What is Mos Terminal?

Mos Terminal is a browser-based trading terminal for Binance USDⓈ-M perpetual futures. It puts up to eight live charts, symbol-tagged news and one-click orders on one screen, and adds risk controls that run on our server: a hard stop for every position and a day breaker. It is currently in an invite-only beta.

What is a hard stop and how does it work?

A hard stop is a loss limit in US dollars that you set once and that applies to every position. Our server watches your open positions around the clock, and when a position's unrealized loss reaches that amount, it closes the position at market. It checks the loss on live prices for a moment before acting, so a single stray print does not close your position. Because it runs on the server, it keeps working when your browser is closed or your laptop is asleep.

How do I set a daily loss limit in Mos Terminal?

Open the ARM panel and enter your hard stop amount; the same panel also caps the size of a single order and your total open size. When the hard stop closes a position, the day breaker switches on and blocks new positions until the next day (Istanbul time). Closing positions always stays allowed, and you can reset the breaker earlier with a two-step confirmation. Setting the hard stop to 0 turns it off.

Does Mos Terminal hold my funds or have withdrawal access?

No. Your funds stay in your own Binance account, and Mos places orders through an API key that you create. Mos refuses keys that can withdraw or transfer funds, so the key it uses can trade but cannot move money out of your account.

How are my API keys protected?

The key must be trade-only: withdrawals and transfers turned off, and access restricted to our server's IP address, so a leaked copy cannot be used from anywhere else. Saved keys are encrypted with AWS KMS. Mos re-checks the key's permissions regularly and locks new trading if they ever change; closing positions stays possible.

Which exchanges does Mos Terminal support?

Today Mos Terminal supports Binance USDⓈ-M perpetual futures. You connect your own Binance account with an API key. Other exchanges are not supported at the moment.

How much does it cost, and is there a trial?

There is one plan: 149 USD per month, with every feature included. During the private beta, the first applicants get a 14-day Early Access Pass with full access, free and with no card needed. Payments follow the Terms and the Refund policy.

How do I join the invite-only beta?

Request an invite on the Contact page: pick your approximate monthly trading volume and tell us how to reach you by email or Telegram. Seats open in small cohorts, and we contact you when one is available. Your invitation includes a one-time link to open the terminal.

Where does the terminal run?

In your web browser on Mac or Windows; there is nothing to install. You open it with the Launch Terminal button and sign in with a one-time code from an authenticator app on your phone. The risk controls run on our server, not in your browser.

How is a hard stop different from a stop-loss order?

A stop-loss is an order placed at a price level that waits on the exchange until the market reaches it. A Mos hard stop is a dollar amount: the server applies it to every position you open and closes any position whose unrealized loss reaches it, without a separate order for each trade. It also switches on the day breaker. Many traders use both, and our guide compares them in detail.

What happens if the hard stop is hit while I have other open positions?

Only the position whose loss reached the limit is closed. The day breaker then blocks new positions for the rest of the day, and pending limit orders you placed through Mos to open positions are cancelled. Your other open positions stay open, you can close them at any time, and each of them keeps its own hard stop.

Can I use Mos Terminal on my phone?

Mos Terminal is built for a desktop browser on Mac or Windows, and there is no mobile app. Your phone is still part of the setup, because you sign in with an authenticator app on it. Since the hard stop runs on our server, your positions stay protected even when your computer is off.

How do I get support?

Every member gets personal onboarding when they join. Members reach us on Telegram or by email. If you are not a member yet, use the invite form on the Contact page and we will get back to you.

Can a hard stop guarantee my maximum loss?

No. The hard stop closes at market, so in fast or thin markets the fill can be worse than your limit, and exchange or network problems can delay it. Treat it as a strong safety net rather than a guarantee, and size positions so that a worse fill is still acceptable.

Mos Terminal enforces a hard stop and a day breaker on our server for Binance USDⓈ-M futures, so your limits hold even with the browser closed. It is in invite-only beta.
