## 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.
|
||||

|
||||
|
||||
- Compute the max pain point based on open interest data using
|
||||
deribit's api.
|
||||
[commit](https://pikers.dev/pikers/piker/commit/0d9d6e15ba0edeb662ec97f7599dd66af3046b94)
|
||||
|
||||
### 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.
