Tradier
Connected
Connects live US equity options quotes and chains to this interface.
Get a free access token at tradier.com/products/developer
— your token is under Account → API Access in the Tradier dashboard.
Security & privacy
A Tradier access token is a read-only market data credential. It lets us stream live bid/ask quotes and option chains to your screen. It cannot place orders, access your cash balance, or make any changes to your Tradier account — market data tokens simply don't carry those permissions by design.
Your token is encrypted with AES-256-GCM before storage and never appears in logs or responses.
Recommended planTradier Developer — Free No deposit or trading activity required. Full real-time options data API access.
If you already have a Tradier brokerage account your existing token works here too — no separate developer account needed.
Massive
Connected
Connects US equities and options data via Polygon.io — the engine that powers Massive.
Sign up at massive.com
and copy your API key from the dashboard. A Polygon.io key works here directly too.
Security & privacy
A Polygon.io / Massive API key is a data-only credential — it has no connection to any brokerage account and no ability to initiate trades or access funds. It exists solely to query market data. Encrypted with AES-256-GCM before storage.
Recommended planPolygon.io Starter — $29 / month Real-time US equities data. Options add-on — +$29 / month Required for live options chains.
A Free tier is available with 15-minute delayed data — enough to test the interface before committing.
Tastytrade
Connected
Verifies your Tastytrade
brokerage account to unlock the live US options data feed.
Tastytrade's login API blocks browser-based requests from third-party sites, so you generate the session token yourself and paste it here.
Run this in your terminal:
Security & privacy
Your session token is used for a single verification request to confirm you hold an active Tastytrade account — then immediately discarded. We never store your Tastytrade password or session token. Only the fact that verification succeeded is recorded (provider = "tastytrade"). Session tokens expire in ~24 hours regardless.
Account costTastytrade brokerage — Free to open No minimum deposit. Real-time US options data is included with any active account.
Interactive Brokers
Connect via the free
IB Client Portal Gateway
running on your own machine. Your credentials never leave your computer.

3. Accept the self-signed certificate:
4. Open root/conf.yaml inside the gateway folder and add under cors: origin.whitelist: [https://option.watch]
Security & privacyWe never see your IBKR credentials. All authentication happens inside the IB Client Portal Gateway running on your own machine.

Your username and password stay local and never leave your machine.
Account costIBKR Lite — Free No minimum deposit. IB Client Portal Gateway is free to download and run. Real-time US market data is free for accounts generating ≥$10/month in commissions, otherwise ~$10/month.
Binance
Connect your Binance account to trade European-style crypto options. Generate an API key at Account → API Management — enable Enable Options permission only.
What is an API key and secret?
An API key is like a username for automated access — it identifies your account to the exchange. The API secret is a cryptographic signing key, similar to a password, used to prove each request genuinely came from you. Together they allow this interface to submit and cancel options orders on your behalf.
We only execute orders you explicitly place in the interface — no autonomous trading, no background activity.
Keys are encrypted with AES-256-GCM before storage and never appear in logs or API responses.
We cannot withdraw funds — withdrawal permission must never be enabled on a key used here.
If you ever suspect a key is compromised, revoke it immediately on the exchange and generate a new one.
When creating your API key
Enable Options trading permission only. Never enable Withdrawal. Restrict the key to trusted IP addresses if the exchange supports it. Store your secret safely — exchanges cannot recover it if lost, only regenerate.
