-## Max Pain Calculation for Deribit Options

-This feature, which calculates the max pain point for options traded
-on the Deribit exchange using cryptofeed library.
-
-- Functions in the api module for fetching options data from Deribit.
-  [commit](https://pikers.dev/pikers/piker/commit/da55856dd2876291f55a06eb0561438a912d8241)

-### How to test it?
-
-**Before start:** in order to get this working with `uv`,  you
-**must** use my [`tractor` fork](https://pikers.dev/ntorres/tractor/src/branch/aio_abandons)
-and this branch: `aio_abandons`, the reason is that I cherry-pick the
-`uv_migration` that guille made, for some reason that a didn't dive
-into, in my system y need tractor using `uv` too. quite hacky
-I guess.
-
-1. `uv lock`
-
-2. `uv run --no-dev python examples/max_pain.py`
-
-3. A message should be display, enter one of the expiration date
-   available.
-
-4. The script should be up and running.
