Questions, answered

A few things worth knowing.

Where does my investment money stay?
Your cash and securities remain in your separately held brokerage account. SquaredQ provides signals, execution software, monitoring and technical support. Subscription payments to SquaredQ are separate from capital held at your broker.
Does SquaredQ accept deposits or process withdrawals?
The documented execution software does not implement withdrawal or transfer functionality. Deposits, withdrawals, transfers and account funding are handled through your broker. Never send investment capital to someone claiming it is required to activate a strategy.
Do I connect using OAuth?
No. Alpaca, Webull and Public connect using API credentials. Interactive Brokers connects through Trader Workstation (TWS) or IB Gateway in your dedicated execution environment. SquaredQ does not use OAuth for these connections. Follow your broker’s in-app guide and enter API credentials only in the designated MyAlgo setup interface.
Can I use paper trading?
The documented Alpaca connection offers paper and live modes, and Webull has sandbox and live environments. Public is documented as live only. Other test-account availability and required settings depend on your broker and the current app configuration.
