**Full Changelog**: https://github.com/DaveSkender/Stock.Indicators.Python/compare/1.2.0...1.2.1

New feature:

- allow the use of a custom generic quote class with IQuote interface - 179

This allows you to use your own historical quotes class so you can avoid having to transpose to the provided `Quote` class. You may still use the provided `Quote` class; however, this will give you an additional option. See [Using custom quote classes](https://daveskender.github.io/Stock.Indicators/docs/GUIDE.html#using-custom-quote-classes) in the guide for more information.

Special thanks to MithrilMan for this contribution.

Minor bug fixes:

- fix: divide by zero error when using atypical or bad historical quotes data. Null result values for incalculable dates are now returned instead of thrown error. 188

Chores:

- add bad test data and corresponding unit tests to cover more unusual data scenarios

Minor breaking change (for few users):

- Replaced `PrepareHistory` with optional `ValidateHistory` method. The former is no longer needed to improve performance in high-frequency operations.

Chores:

- Removed internal indexes - 180

Resolved issues:

- Bollinger band divide by zero when the standard deviation is zero - 183
- Error when resizing and reusing historical quotes between calls - 170

- refactor: replace custom BadParameterException with standard ArgumentOutOfRangeException - 177
- revert bug fix that was introduced in version 1.0.6 since it created a scenario that would have corrupted history data if its length were manipulated and reused - 181
