Hello, I’m exploring creating a trading app that allows users to copy portfolio’s from professionals (like Etoro’s CopyPortfolio feature). Would like to charge a fee to provide some benefit to professionals to share their portfolio. Does Alpaca allow a developer to charge a fee (fixed amount or %) from their users’ portfolio and move money to the developer account? Thanks ---

I am wondering about this as well. Is it at all possible to create a trade platform to serve as the middleman with alpaca as the broker and create a true multi tenant trading platform whereby alpaca only serves as the API and order filling entity ---

I would imagine this is covered in the TOS and a lawyer could answer this question
