Your bot trades through one broker at a time, and you choose which one. The control is on the Strategies page, in the Broker card — the line at the top always tells you where your money is actually going:
Currently executing on TastyTrade
Every broker in the list runs the same strategies, the same filters and the same risk settings. What changes is whose account the orders land in, and what that account is able to do.
What you can trade where
| Broker | Trades | Notes |
|---|---|---|
| TastyTrade | Options (single-leg and spreads) | The default. The broker holds your bracket, so your stop and target rest at the exchange. |
| Robinhood | Single-leg options only | Uses Robinhood's Agentic Trading account. Your stop rests at the broker; the take-profit is watched by your bot. See Trading on Robinhood. |
| Plus500 Futures | CME index futures (ES, MES, NQ, MNQ, RTY, M2K) | Runs against a Plus500 US Futures account through the T4 platform, in simulation or live. See Plus500 Futures. |
| Paper | Options and futures | Simulated money, no broker account needed. See Paper Trading. |
Spreads, multi-leg exits and futures aren't available on every broker — the per-broker topics above say exactly what each one can and can't do, and your bot simply won't place an order a broker can't support.
A broker appears once it's set up — not before
The list isn't the same for everyone. A broker shows up in your picker only when both of these are true:
- Your bot has that broker's credentials. They live in your bot's own app settings (Config Vars), never in this app — nobody types a brokerage password into the portal. Until they're set, your bot doesn't offer the broker at all, so you won't see it.
- You hold the market it trades. Options brokers show for options customers, futures brokers for anyone who holds the futures market from the Marketplace.
Paper is always there, for everyone, whatever you hold — it's how you try a market before you pay for it.
If a broker is listed but greyed out with Credentials not configured, the credentials are missing or incomplete. Clicking it tells you exactly which ones, by name.
Switching
- Close everything on the broker you're leaving. If anything is still open, you'll get Cannot switch brokers, listing each open position. The Flatten All Now button closes them and retries in one step — it sells at the market, so use it deliberately.
- Click the broker you want. Some switches take effect immediately.
- Restart when asked. Others save your choice and show a Restart required banner, because the connection to the new broker is built when your bot boots. Hit Restart ATS now and give it 20–40 seconds; the banner clears itself when the new broker is live.
Until that restart finishes, the top line still names the old broker — and that's the truth, not a display lag. Your saved choice isn't trading anything yet.
What carries over, and what doesn't
Your strategies, alert sources, risk settings and killswitches are all account-wide — they follow you to the new broker untouched. Your trade history doesn't merge: pages with a Live / Paper switch keep simulated trades separate from real ones, and each trade is stamped with the broker that executed it, so a switch never rewrites what already happened.
Tip
The safest way to try a new broker is not to guess. Run it on Paper first to confirm the strategy behaves the way you expect, then switch — the settings are identical either way.
Note
If your account is paper-locked, the picker is read-only and says so. That's a permanent restriction on the license, not something a setting can undo — contact support if you think it's wrong.
