# CCXT for C#

A comprehensive guide to using CCXT in C# and .NET projects for cryptocurrency exchange integration.

## Installation

### Via NuGet Package Manager
```bash
dotnet add package CCXT.NET
```

Or via Visual Studio:
1. Right-click project → Manage NuGet Packages
2. Search for "CCXT.NET"
3. Click Install

### Requirements
- .NET Standard 2.0 or higher
- .NET Core 2.0+ / .NET 5+ / .NET Framework 4.6.1+

## Quick Start

### REST API
```csharp
using ccxt;

var exchange = new Binance();
await exchange.LoadMarkets();
var ticker = await exchange.FetchTicker("BTC/USDT");
Console.WriteLine(ticker);
```

### WebSocket API - Real-time Updates
```csharp
using ccxt.pro;

var exchange = new Binance();
while (true)
{
    var ticker = await exchange.WatchTicker("BTC/USDT");
    Console.WriteLine(ticker.Last);  // Live updates!
}
await exchange.Close();
```

## REST vs WebSocket

| Feature | REST API | WebSocket API |
|---------|----------|---------------|
| **Use for** | One-time queries, placing orders | Real-time monitoring, live price feeds |
| **Import** | `using ccxt;` | `using ccxt.pro;` |
| **Methods** | `Fetch*` (FetchTicker, FetchOrderBook) | `Watch*` (WatchTicker, WatchOrderBook) |
| **Speed** | Slower (HTTP request/response) | Faster (persistent connection) |
| **Rate limits** | Strict (1-2 req/sec) | More lenient (continuous stream) |
| **Best for** | Trading, account management | Price monitoring, arbitrage detection |

**Method naming:** C# uses PascalCase - `FetchTicker` not `fetchTicker`, `WatchTicker` not `watchTicker`

## Creating Exchange Instance

### REST API
```csharp
using ccxt;

// Public API (no authentication)
var exchange = new Binance
{
    EnableRateLimit = true  // Recommended!
};

// Private API (with authentication)
var exchange = new Binance
{
    ApiKey = "YOUR_API_KEY",
    Secret = "YOUR_SECRET",
    EnableRateLimit = true
};
```

### WebSocket API
```csharp
using ccxt.pro;

// Public WebSocket
var exchange = new Binance();

// Private
