rshioaji 1.5.1

Rust implementation of Shioaji trading API for Taiwan financial markets

Shioaji Python Bindings

Python bindings for the high-performance rshioaji Rust library - a next-generation client for Taiwan stock market data.

Features

• High Performance: Built on the Rust rshioaji core library for maximum throughput
• Type Safe: Full type annotations and comprehensive error handling
• Real-time Data: Support for stock ticks, bid/ask quotes, and futures/options data
• Multi-exchange: TSE, OTC, OES, and TAIFEX support
• Sync & Async: Both synchronous and asynchronous clients available
• Callback Support: Register callbacks for real-time data processing

Installation

Development Install (from source)

# Clone the repository
git clone <repository-url>
cd rshioaji/python

# Build and install with uv
uv build
uv run python examples/snapshot.py

Production Install (when published)

Quick Start

Sync Client

import shioaji

# Create client in simulation mode
api = shioaji.Shioaji(simulation=True)

# Login
api.login("your_api_key", "your_secret_key")

# Create a contract for Taiwan Semiconductor (2330)
contract = shioaji.BaseContract("STK", "TSE", "2330")

# Get snapshots
snapshots = api.snapshots([contract])
for snap in snapshots:
    print(f"{snap.code}: {snap.close}")

# Subscribe to real-time tick data
api.subscribe(contract, "tick")

Async Client

import asyncio
import shioaji

async def main():
    api = shioaji.ShioajiAsync(simulation=True)
    await api.login("your_api_key", "your_secret_key")

    contract = shioaji.BaseContract("STK", "TSE", "2330")
    snapshots = await api.snapshots([contract])

    await api.subscribe(contract, "tick")

asyncio.run(main())

Examples

Callback-based Real-time Data

import shioaji

api = shioaji.Shioaji(simulation=True)
api.login("api_key", "secret_key")

def on_tick(tick):
    print(f"Tick: {tick.code} @ {tick.close}")

def on_bidask(bidask):
    print(f"BidAsk: {bidask.code} Bid={bidask.bid_price[0]}")

api.set_on_tick_stk_v1_callback(on_tick)
api.set_on_bidask_stk_v1_callback(on_bidask)

contract = shioaji.BaseContract("STK", "TSE", "2330")
api.subscribe(contract, "tick")
api.subscribe(contract, "bid_ask")

# Callbacks run in background threads
import time
time.sleep(60)

Receiver-based Data Polling

import shioaji

api = shioaji.Shioaji(simulation=True)
api.login("api_key", "secret_key")

contract = shioaji.BaseContract("STK", "TSE", "2330")
api.subscribe(contract, "tick")

receiver = api.get_tick_stk_v1_receiver()

# Poll for data
while True:
    tick = receiver.try_recv()
    if tick:
        print(f"Tick: {tick.code} @ {tick.close}")

Snapshots

import shioaji

api = shioaji.Shioaji(simulation=True)
api.login("api_key", "secret_key")

contracts = [
    shioaji.BaseContract("STK", "TSE", "2330"),  # TSMC
    shioaji.BaseContract("STK", "TSE", "2317"),  # Hon Hai
    shioaji.BaseContract("FUT", "TAIFEX", "TXFB6"),  # Futures
]

snapshots = api.snapshots(contracts)
for snap in snapshots:
    print(f"{snap.code}: close={snap.close}, volume={snap.total_volume}")

Performance Optimization

Latency Comparison

Based on our benchmarks (120s, ~88 FOP ticks):

Method	P50 Latency	Notes
try_recv() polling	Fastest	Tight loop, highest CPU
Sync callback	~5µs slower	Dedicated thread
Async + uvloop	~6µs slower	Recommended for async
Async (default)	~136µs slower	Default asyncio overhead

Using uvloop (Recommended for Async)

For async users, we strongly recommend using uvloop to eliminate asyncio event loop overhead:

# Install uvloop
pip install uvloop
# or with uv
uv add uvloop

import asyncio
import uvloop
import shioaji

# Install uvloop before running async code
uvloop.install()

async def main():
    api = shioaji.ShioajiAsync()
    await api.login("api_key", "secret_key")

    contract = shioaji.BaseContract("STK", "TSE", "2330")
    await api.subscribe(contract, "tick")

    receiver = await api.get_tick_stk_v1_receiver()
    while True:
        tick = await receiver.recv()
        print(f"Tick: {tick.code} @ {tick.close}")

asyncio.run(main())

Low-Latency Options

For the lowest latency requirements:

Option 1: Sync Callback (Simple)

api = shioaji.Shioaji()
api.set_on_tick_stk_v1_callback(on_tick)
api.subscribe(contract, "tick")

Option 2: try_recv() Polling (Fastest)

receiver = await api.get_tick_stk_v1_receiver()
while True:
    tick = receiver.try_recv()  # Non-blocking, bypasses asyncio
    if tick:
        process(tick)

Development

Building from Source

cd python

# Build the package
uv build

# Run example
uv run python examples/snapshot.py
uv run python examples/callback.py

Architecture

The Python bindings are built using:

• PyO3: Rust-Python FFI bindings
• maturin: Build tool for Rust-based Python extensions
• Tokio: Async runtime for handling real-time data streams
• rshioaji: Core Rust library for market data processing
