shioaji-logo sinopac-logo

Shioaji is a trading API provided by Sinopac that offers a comprehensive and user-friendly platform for accessing the Taiwan financial markets. Shioaji is a cross-language, cross-platform universal trading platform — accessible through native Python bindings (import shioaji as sj) or any HTTP-capable language (JavaScript/TypeScript, Go, C/C++, C#, Rust, Java/Kotlin) for trading stocks, futures, options, and combo orders. On the Python side, Shioaji integrates seamlessly with familiar packages such as numpy, scipy, pandas, pytorch, and tensorflow for building custom trading models; on the HTTP side, a built-in OpenAPI interactive document, SSE real-time streaming, and a visual Dashboard provide live monitoring of server status, SSE connections, CA certificates, accounts, and API usage. Whether for traders new to the world of programmatic trading or experienced developers seeking a more powerful platform, Shioaji is built to deliver.

Quickstart

Expand the section that matches your preferred development language.

Python

Initialization (login + activate certificate)

import shioaji as sj

api = sj.Shioaji()
accounts = api.login(api_key="YOUR_KEY", secret_key="YOUR_SECRET")
api.activate_ca(
    ca_path="/c/your/ca/path/Sinopac.pfx",
    ca_passwd="YOUR_CA_PASSWORD",
)

Just import the API library like other popular Python packages and create the instance to start using it. After logging in, the API is ready for market data queries; once the certificate is activated, order placement is enabled.

Subscribe to Streaming Market Data

api.subscribe(api.Contracts.Stocks["2330"], quote_type="tick")
api.subscribe(api.Contracts.Stocks["2330"], quote_type="bid_ask")
api.subscribe(api.Contracts.Futures["TXFC0"], quote_type="tick")

Subscribe to real-time market data. Pass a contract into the subscribe function and specify a quote_type to begin receiving streaming data.

Place Order

contract = api.Contracts.Stocks["2890"]
order = sj.StockOrder(
    price=9.6,
    quantity=1,
    action=sj.Action.Buy,
    price_type=sj.StockPriceType.LMT,
    order_type=sj.OrderType.ROD,
    order_lot=sj.StockOrderLot.Common,
    account=api.stock_account,
)
trade = api.place_order(contract, order)

As with subscribing to market data using a contract, an order must first be defined and then passed alongside the contract into the place_order function. The function returns a trade object representing the order's status.

Cross-language

Start the Server

shioaji server start

Once the server is running, all trading capabilities are exposed as RESTful endpoints accessible from any HTTP-capable language (JavaScript, Go, C#, Java, Rust, C/C++, etc.).

Verify that the server has started successfully:

curl http://localhost:8080/api/v1/health

Getting Started

Once the server is running, the following entry points are available:

Purpose	URL
Dashboard (live monitoring & management)	`http://localhost:8080/`
OpenAPI document (browse API, run tests in-browser)	`http://localhost:8080/docs`
Custom apps (entry point for self-uploaded web apps)	`http://localhost:8080/apps/<name>/`

Open /docs to browse all endpoints, inspect request/response schemas, generate code samples in multiple languages, and test directly from the browser.

Custom Web Apps

Custom web apps can be uploaded from the Dashboard's Custom Apps card and run alongside the Dashboard; once uploaded, an app is served at http://localhost:8080/apps/<name>/.

Supported formats: a single HTML file, or a build output folder from frontend frameworks such as Vite / React / Vue (containing index.html).
Upload steps: log in to the Dashboard → click Custom Apps → Upload → select the file or folder → set the application name <name>.
Project template: @sinotrade/create-shioaji-app — scaffolds a Shioaji frontend project with one command.

CLI

The shioaji CLI provides direct server management, market data queries, and order placement.

shioaji --help        # list all commands
shioaji tree --all    # show full command tree (with parameters and descriptions)

Server Management

Purpose	Command
Start HTTP server (simulation mode)	`shioaji server start`
Start HTTP server (production mode)	`shioaji server start --production`
Check mode and authentication status	`shioaji server check`
Show daemon status	`shioaji server status`
Stop daemon	`shioaji server stop`

Conclusion

This quickstart shows the multiple ways to access Shioaji — from native Python, HTTP API, and CLI to custom web apps. The focus is on building an easy-to-use, cross-language trading API that lets any developer trade Taiwan's financial markets with confidence.
