cqr-fundflows 0.2.0

Compiled Bloomberg BQuant fund-flow analytics dashboard

CQR Fund Flows

Compiled Bloomberg BQuant dashboard for fund-flow analysis.

Supported environment

• Bloomberg BQuant
• Windows 64-bit
• CPython 3.11
• Bloomberg's bql module already available in the environment

Installation

python -m pip install cqr-fundflows

Usage

Run in a BQuant notebook:

from cqr_fundflows import launch_dashboard

launch_dashboard()

Only launch_dashboard() is part of the supported public API.

Access control

There is no licence key to paste into the notebook. At import time, the compiled extension reads Bloomberg BQuant's protected UUID environment variable and asks the CQR HTTPS authorization endpoint whether that Bloomberg USER ID has an active Fund Flows entitlement.

Access is granted only when all of the following are true:

• the client account exists;
• its professional email address has been verified;
• CQR has manually marked the Fund Flows entitlement as active;
• the entitlement has started and has not expired.

The check fails closed when the UUID is missing or when the authorization service cannot be reached. No client password, private API credential or service-role key is included in the Python package.

See ACCESS_CONTROL.md for the one-time Supabase and website deployment.

Distribution model

The PyPI release must contain the compiled Windows wheel only. Do not publish a source distribution (.tar.gz), because it would disclose the Cython source. Keep the source repository private.

Local Windows build

py -3.11 -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip build twine
python -m build --wheel
python -m twine check .\dist\*

The expected output is similar to:

cqr_fundflows-0.1.0-cp311-cp311-win_amd64.whl

Limitation

Cython compilation makes direct inspection more difficult, but it is not an absolute protection against reverse engineering.
