> Note that ETF Holding data, corporate action data, and possibly factor model data would be required to reproduce Double’s Direct Index strategies. Unfortunately this data is not generally free and would require a fair bit of work to get Oracle working.

It would be interesting to have an open source direct indexing system with plugins for different brokerages. A CLI tool that provides recommended trades and an option to accept or cancel would be perfect.
