Databento / OPRA

Databento’s OPRA feed gives the OMS live prices for US equity options, so option positions are marked to market and show unrealized P&L. It is a price source only.

What it covers

Section titled “What it covers”
  • The consolidated top of book (NBBO) across the US options exchanges — Databento’s cmbp-1 schema.
  • Only the contracts you hold: the OMS subscribes to held option positions and adds newly opened ones mid-session.

You need a Databento account with live OPRA access, which is a paid subscription.

Credentials

Section titled “Credentials”

One API key. Enter it in the cockpit under Data feeds → databento-opra → Credentials (Test, then Save), then reload:

Terminal window
export OMS_ADMIN=$(sed -n 's/^admin_password = "\(.*\)"/\1/p' ~/.config/oms/oms.toml)


curl -s -X POST localhost:3001/admin/connections/reload -H "Authorization: Bearer $OMS_ADMIN"

databento-opra should report Registered.
