Features

• Many exchanges supported with public, private and web socket API
• Easy to use code and API
• Optional global market symbol normalization, since each exchange has their own way of doing market symbols
• Runs anywhere .NET runs. (Windows, Mac, Linux, Containers, Serverless, iOS, Android, etc.)
• Can be used from many different C# platforms
• Has a great CLI that enables you to use all features from all exchanges right from your command line.

The following cryptocurrency services are supported:

• Cryptowatch (partial)

Exchange constructors are private, to get access to an exchange in code use:

ExchangeAPI.GetExchangeAPIAsync<>().

Installing the CLI

On *nix systems:

• Run this command curl https://github.com/DigitalRuby/ExchangeSharp/raw/main/install-console.sh | sh

On Windows (or manually):

• Download the latest binaries for your OS.
• Unzip it into a folder that is in your environment variable PATH (ctrl + shift + pause|break -> Environment Variables)
• Use it from your preferred command-line emulator (e.g. Powershell, cmd, etc.)
• exchange-sharp --help shows all available commands

Notes

ExchangeSharp uses marketSymbol to refer to markets, or pairs of currencies.

Please send pull requests if you have made a change that you feel is worthwhile, want a bug fixed or want a new feature. You can also donate to get new features.

Building/Compiling

Websockets

If you must use an older Windows (older than win8.1), you'll need to use the Websocket4Net nuget package, and override the web socket implementation by calling

ExchangeSharp.ClientWebSocket.RegisterWebSocketCreator(
    () => new ExchangeSharpConsole.WebSocket4NetClientWebSocket()
);

See WebSocket4NetClientWebSocket.cs for implementation details.

Nuget

dotnet CLI

dotnet add package DigitalRuby.ExchangeSharp --version 1.2.0

Package Manager on VS

PM> Install-Package DigitalRuby.ExchangeSharp -Version 1.2.0

Examples

Creating an order

There's a lot of examples on how to use the API in our console application.
e.g. ExampleOption.cs

Getting ticker info via Web Sockets

public static async Task Main(string[] args)
{
    // create a web socket connection to Binance. Note you can Dispose the socket anytime to shut it down.
    using var api = await ExchangeAPI.GetExchangeAPIAsync<ExchangeBinanceAPI>();
    // the web socket will handle disconnects and attempt to re-connect automatically.
    using var socket = await api.GetTickersWebSocket(tickers =>
    {
        Console.WriteLine("{0} tickers, first: {1}", tickers.Count, tickers.First());
    });

    Console.WriteLine("Press ENTER to shutdown.");
    Console.ReadLine(true);
}

Authentication

Private api calls like placing orders require you to call LoadApiKeys first. You can generate an api keys file by running the bundled console application and choosing the generate key file option.

Logging

ExchangeSharp uses NLog internally currently. To log, use ExchangeSharp.Logger.

Do not use Console.WriteLine to log messages in the lib project.

Provide your own nlog.config or app.config nlog configuration if you want to change logging settings or turn logging off.

Caching

The ExchageAPI class provides a method caching mechanism. Use MethodCachePolicy to put caching behind public methods, or clear to remove caching. Some methods are cached by default. You can set ExchangeAPI.UseDefaultMethodCachePolicy to false to stop all caching as well.

You can also set request cache policy if you want to tweak how the http caching behaves.
