StockSharp Messages Library

The Messages project contains the essential message definitions shared across the StockSharp (S#) trading framework. Messages are the contracts used by connectors, adapters and other services for all interactions such as connecting to brokers, requesting market data or placing orders.

Overview

Message Types Enumeration – MessageTypes lists every supported message kind.
Base Classes – classes like Message, BaseConnectionMessage and BaseSubscriptionMessage provide common fields and behaviour.
Asynchronous Processing – MessageAdapter and AsyncMessageProcessor handle messages asynchronously.
Utility Helpers – classes such as ReConnectionSettings control reconnection and subscription options.

Core Messages

The library defines messages for all major trading activities:

Connection – ConnectMessage, DisconnectMessage, ConnectionLostMessage and ConnectionRestoredMessage.
Security Information – SecurityMessage, BoardMessage and BoardStateMessage.
Market Data – MarketDataMessage, Level1ChangeMessage, QuoteChangeMessage, TimeFrameCandleMessage and related candle messages.
Orders and Trades – OrderRegisterMessage, OrderReplaceMessage, OrderCancelMessage, OrderGroupCancelMessage, OrderStatusMessage and ExecutionMessage.
Portfolio and Positions – PortfolioMessage, PortfolioLookupMessage and PositionChangeMessage.
Service Messages – TimeMessage, NewsMessage, ErrorMessage and others.

The project targets .NET Standard 2.0 and .NET 6.0 for cross-platform compatibility.

Usage Example

Below is a minimal example of creating a market data subscription message:

using StockSharp.Messages;

var mdMessage = new MarketDataMessage
{
    DataType2 = DataType.Ticks,
    IsSubscribe = true,
    TransactionId = 1,
    SecurityId = new SecurityId
    {
        SecurityCode = "AAPL",
        BoardCode = "NASDAQ"
    }
};

Such messages are passed to an adapter, which forwards them to the broker or data provider.

Documentation

Further details on messages and architecture can be found in the StockSharp documentation.
