What Is This? / 这是什么？

Quant.Infra.Net abstracts the complexity of connecting to financial data sources, brokers, and notification channels behind a unified C# API. You write strategy logic once — the library handles the rest.

Core Capabilities / 核心基础设施:

Module	What It Does / 能力说明
Data Source / 数据源	Unified market data ingestion from Yahoo Finance & Binance (Spot/Futures), with local CSV/SQL persistence. 聚合多源行情（Yahoo/Binance），并支持本地持久化。
Broker & Orders / 订单执行	Standardized trading interfaces for Binance Futures, seamlessly switching between testnet simulation and live execution. 币安合约标准化交易接口，无缝切换测试网模拟与实盘下单。
Notification / 通知推送	Real-time strategy alerts via DingTalk bots, WeChat Work webhooks, and SMTP/Brevo email pipelines. 内置钉钉、企业微信及邮件通道，实现策略信号的即时触达。

Why this matters / 为什么重要:

• One NuGet package — no juggling multiple SDKs from different vendors
• Unified interfaces — ITraditionalFinanceSourceDataService, IBrokerService, IEmailService — swap implementations without changing your strategy code
• Out-of-the-box analysis — ADF test, OLS regression, Z-Score, Sharpe ratio — all included

Quick Start / 快速开始

# Install via NuGet
dotnet add package Quant.Infra.Net --version 1.5.1

// Register all modules
var services = new ServiceCollection();
services.AddQuantInfraNet();

// Fetch OHLCV data from Yahoo Finance
var dataService = services.BuildServiceProvider()
    .GetService<ITraditionalFinanceSourceDataService>();
var bars = await dataService.GetOhlcvListAsync("AAPL", DateTime.Now.AddDays(-30), DateTime.Now);

// Place order via Binance Futures (testnet)
var binance = services.BuildServiceProvider()
    .GetService<IBinanceUsdFutureService>();
await binance.SetUsdFutureHoldingsAsync("BTCUSDT", 0.01, PositionSide.Long);

// Send notification alert when strategy triggers
var dingTalk = services.BuildServiceProvider()
    .GetService<IDingtalkService>();
await dingTalk.SendNotificationAsync("[Alert] BTC long position opened", token, secret);
