```
usage: fib [-p PERIOD] [--start START] [--end END] [--export {csv,json,xlsx}] [-h]
```

Calculates the fibonacci retracement levels

The fibonocci retracement works by looking at a minimum and maximum point.  Between these values, there is typically support/resistance at
23.5 %, 38.2%, 50% and 61.8%.  Those values follow the golden ratio from the fibonocci sequence.

The `--start` and `--end` flags allow the user to select dates for the min and max points as your retracement levels.  Both flags are required if using.

```

  --end END             Ending date to select (default: None)
  --export {csv,json,xlsx}
                        Export dataframe data to csv,json,xlsx file (default: )
