Core Type System Upgrade + +**Before**: All price/quantity/volume fields used `String` types +**After**: Type-safe wrappers using `rust_decimal::Decimal` + +### 2. New Type-Safe Types + +#### Symbol Type +```rust +#[derive(Debug, Clone, PartialEq, Eq, Hash, Serialize, Deserialize)] +pub struct Symbol { + pub base: String, + pub quote: String, +} + +impl Symbol { + pub fn new(base: impl Into, quote: impl Into) -> Result + pub fn from_string(symbol: &str) -> Result + pub fn to_string(&self) -> String +} +``` + +#### Price Type +```rust +#[derive(Debug, Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Serialize, Deserialize)] +#[serde(transparent)] +pub struct Price(#[serde(with = "rust_decimal::serde::str")] pub Decimal); +``` + +#### Quantity Type +```rust +#[derive(Debug, Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Serialize, Deserialize)] +#[serde(transparent)] +pub struct Quantity(#[serde(with = "rust_decimal::serde::str")] pub Decimal); +``` + +#### Volume Type +```rust +#[derive(Debug, Clone, Copy, PartialEq, Eq, PartialOrd, Ord, Serialize, Deserialize)] +#[serde(transparent)] +pub struct Volume(#[serde(with = "rust_decimal::serde::str")] pub Decimal); +``` + +### 3. Updated Core Data Structures + +All core types now use the new unified types: + +- `Market` +- `OrderRequest` +- `OrderResponse` +- `Ticker` +- `OrderBookEntry` +- `OrderBook` +- `Trade` +- `Kline` +- `Balance` +- `Position` +- `FundingRate` + +### 4. Dependency Addition + +Added `rust_decimal` with serde support: +```toml +rust_decimal = { version = "1.35", features = ["serde-with-str"] } +``` + +### 5. Binance Implementation Updated + +**Complete converter implementation** for Binance exchange: +- Updated `convert_binance_market()` to handle new types +- Added proper error handling for type conversions +- Updated WebSocket message parsing +- Updated REST API K-line parsing + +### 6.

High Precision +- **Before**: String parsing issues, potential precision loss +- **After**: `rust_decimal::Decimal` provides arbitrary precision + +### 3. Performance +- **Before**: String allocations for every price/quantity +- **After**: Copy types with `Decimal` backend + +### 4. Comparisons +```rust +let price1 = Price::from_str("50000.25")?; +let price2 = Price::from_str("50000.30")?; +assert!(price1 < price2); // Type-safe comparison +``` + +### 5. Arithmetic Operations +```rust +let price = Price::from_str("100.50")?; +let quantity = Quantity::from_str("2.5")?; +let total = price.value() * quantity.value(); // Safe arithmetic +``` + +### 6.
