All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.2.0] - 2025-11-07

### Added
- Add basic security policy (`SECURITY.md`)
- Add Elixir `1.18` and `1.19` to CI
- Added type-specific order request schemas (`MarketOrderRequest`, `LimitOrderRequest`, `StopOrderRequest`, `MarketIfTouchedOrderRequest`, `TakeProfitOrderRequest`, `StopLossOrderRequest`, `GuaranteedStopLossOrderRequest`, `TrailingStopLossOrderRequest`) with type-specific defaults and validations

### Changed
- Updated dependencies:
  - Bumped `ecto` from 3.13.3 to 3.13.4
  - Bumped `recase` from 0.9.0 to 0.9.1
  - Bumped `ex_doc` from 0.38.4 to 0.39.1
- Updated `ecto` enums to align with API defaults:
  - `OrderRequest.time_in_force` default is now `:FOK`
  - `OrderRequest.position_fill` default is now `:DEFAULT`
  - `GuaranteedStopLossDetails.time_in_force` default is now `:GTC`
  - `StopLossDetails.time_in_force` default is now `:GTC`
  - `TakeProfitDetails.time_in_force` default is now `:GTC`
  - `TrailingStopLossDetails.time_in_force` default is now `:GTC`
- **BREAKING** `CreateOrder` now uses polymorphic embeds with separate schemas per order type. The `type` field must now be explicitly provided when creating orders; it no longer defaults to `:MARKET`. Each order type now has type-specific defaults for `time_in_force` (e.g., `MARKET` defaults to `FOK`, `LIMIT` defaults to `GTC`) and type-specific required field validations (e.g., `LIMIT` orders require `price`, `TRAILING_STOP_LOSS` orders require `distance` and `trade_id`)
- **BREAKING** `ReplaceOrder` now uses polymorphic embeds with separate schemas per order type, matching the `CreateOrder` implementation. The `type` field must now be explicitly provided when replacing orders. Each order type now has type-specific defaults for `time_in_force` and type-specific required field validations.

### Fixed
- Fixed `CreateOrder` and `ReplaceOrder` to return validation errors instead of raising when an invalid order type is provided. Non-bang functions now properly return `{:error, %ExOanda.ValidationError{}}` instead of raising exceptions.

### Removed
- Removed `OrderRequest` schema module as it has been superseded by type-specific order request schemas (`MarketOrderRequest`, `LimitOrderRequest`, etc.)


## [0.1.1] - 2025-10-22

### Changed
- Updated dependencies:
  - Bumped `req` from 0.5.6 to 0.5.15
  - Bumped `polymorphic_embed` from 5.0.0 to 5.0.3
  - Bumped `typed_ecto_schema` from 0.4.1 to 0.4.3
  - Bumped `ecto` from 3.12.2 to 3.13.3
  - Bumped `dialyxir` from 1.4.3 to 1.4.6
  - Bumped `recase` from 0.8.1 to 0.9.0
  - Bumped `yaml_elixir` from 2.11.0 to 2.12.0
  - Bumped `ex_doc` from 0.34.2 to 0.38.4
  - Bumped `credo` from 1.7.7 to 1.7.13
  - Bumped `excoveralls` from 0.18.2 to 0.18.5

### Fixed
- Fixed type for `Positions.close_position/5`, `body` was incorrectly marked as `String.t()` in the spec; updated to `map()`
- Fixed streaming JSON decode errors caused by incomplete JSON chunks by implementing proper buffering logic

## [0.1.0] - 2025-10-18

### Changed
- Released to Hex.pm; updated `mix.exs`, `README.md` accordingly

## [0.0.21] - 2025-10-16

### Added
- Added `CHANGELOG.md`
- Added error handling and telemetry sections to `README.md`

### Changed
- **BREAKING** Changed `Connection.telemetry` to reference a new `Telemetry` struct, for enabling telemetry, using the default logger provided by `Req.Telemetry` and passing options to `Req.Telemetry`.
- **BREAKING** streaming functions without a bang (e.g. `price_stream`) now pass an ok/error tuple with the event to the specified handler function, whereas previously the unwrapped value was being sent

### Fixed
- Fixed transaction event schemas that were missing type specs
- **BREAKING** Fixed streaming transform behavior, previously calling a streaming function without a bang would still raise on a JSON decode error
    - Now the function will return an error tuple
