Which brokers does it work with?
Charles Schwab, including thinkorswim accounts, through Schwab’s official Trader API. It is not affiliated with Schwab.
Does it place trades on its own?
No. Order posting is off by default, and when you switch it on, every order is something you start and confirm yourself.
Does it store my Schwab password?
No. You log in on Schwab’s own page (OAuth). The access tokens OptionFlow receives are encrypted with a key derived from your own OptionFlow password.
Can I see history for trades I opened before joining?
Yes — up to about two years back, using licensed historical options data with Greeks rebuilt from the historical prices.
Why don’t my Greeks match my broker’s exactly?
OptionFlow calculates its own implied volatility and Greeks so its pricing stays self-consistent. Small differences between platforms are normal.
What does it cost?
Free during the beta.
How do I get access?
Access is invite-only for now. Use the “Request an invite” link and we’ll get back to you.
Does it work on my phone?
It’s designed for a desktop browser and built for wide screens — charts and grids can pop out into separate windows for multi-monitor setups.
