High-performance async trading API client for Python supporting BingX and Bybit exchanges with intelligent session and cache management

aiotrade

High-performance async trading API client for Python supporting BingX and Bybit exchanges with intelligent session and cache management.

Architecture

The library uses a sophisticated architecture for optimal performance:

Session Management

• Shared Session: SharedSessionManager creates a single aiohttp session with high-performance connection pooling
• Individual Sessions: Clients automatically create individual sessions if shared session isn't initialized
• Connection Pooling: Up to 2000 concurrent connections with smart distribution per host

Client Caching

• TTL Cache: BingxClientsCache and BybitClientsCache cache client instances with 10-minute lifetime
• Lock-Free: No blocking operations for maximum performance
• Lazy Cleanup: Expired entries removed on access, not proactively

Installation

poetry add aiotrade-sdk

Quick Start

Option 1: Shared Session (Recommended for Production)

from aiotrade import SharedSessionManager, BingxClient, BybitClient

# Initialize shared session at startup (once per application)
SharedSessionManager.setup(max_connections=2000)

# Create clients for different exchanges - they automatically use the shared session
bingx_client = BingxClient(api_key="bingx_key", api_secret="bingx_secret", demo=True)
bybit_client = BybitClient(api_key="bybit_key", api_secret="bybit_secret", testnet=True)

try:
    # Use clients for API calls
    bingx_assets = await bingx_client.get_spot_account_assets()
    bybit_tickers = await bybit_client.get_tickers(category="spot")
finally:
    # Close shared session at shutdown
    await SharedSessionManager.close()

Option 2: Individual Sessions

from aiotrade import BingxClient, BybitClient

# BingX client with individual session
async with BingxClient(api_key="your_key", api_secret="your_secret", demo=True) as client:
    assets = await client.get_spot_account_assets()
    print(f"BingX assets: {assets}")

# Bybit client with individual session
async with BybitClient(api_key="your_key", api_secret="your_secret", testnet=True) as client:
    tickers = await client.get_tickers(category="spot")
    print(f"Bybit tickers: {tickers}")

Option 3: Cached Clients

from aiotrade import BingxClientsCache, BybitClientsCache

# Get cached BingX client (creates new if doesn't exist)
bingx_client = BingxClientsCache.get_or_create(
    api_key="your_key",
    api_secret="your_secret",
    demo=True
)

# Get cached Bybit client
bybit_client = BybitClientsCache.get_or_create(
    api_key="your_key",
    api_secret="your_secret",
    testnet=True
)

# Use clients (session management is automatic)
async with bingx_client:
    assets = await bingx_client.get_spot_account_assets()

async with bybit_client:
    tickers = await bybit_client.get_tickers(category="spot")

# Same parameters return the same cached instance
cached_bingx = BingxClientsCache.get_or_create(
    api_key="your_key",
    api_secret="your_secret",
    demo=True
)
assert bingx_client is cached_bingx  # True

Session Behavior

Scenario	Session Type	When Used
SharedSessionManager.setup() called	Shared session	All clients
No shared session initialized	Individual session	Each client
Cached clients	Depends on initialization	Cached per credentials

Cache Features

• Automatic TTL: 10 minutes default, configurable
• Memory Safe: Prevents client accumulation
• High Performance: Lock-free operations
• Background Cleanup: Optional periodic cleanup task

# Configure cache lifetime for each exchange
BingxClientsCache.configure(lifetime_seconds=1800)  # 30 minutes
BybitClientsCache.configure(lifetime_seconds=1800)  # 30 minutes

# Start background cleanup
bingx_cleanup = BingxClientsCache.create_cleanup_task(interval_seconds=300)
bybit_cleanup = BybitClientsCache.create_cleanup_task(interval_seconds=300)

# Manual cleanup
bingx_removed = BingxClientsCache.cleanup_expired()
bybit_removed = BybitClientsCache.cleanup_expired()

API Methods

BingX Client Methods

from aiotrade import BingxClient

client = BingxClient(api_key="your_key", api_secret="your_secret", demo=True)

# Market data
server_time = await client.get_server_time()

# Spot trading
assets = await client.get_spot_account_assets()
tickers = await client.get_spot_tickers()

# Swap trading (perpetual futures)
await client.place_swap_order({
    "symbol": "BTC-USDT",
    "side": "BUY",
    "positionSide": "BOTH",
    "type": "MARKET",
    "quantity": 0.001
})

Bybit Client Methods

from aiotrade import BybitClient

client = BybitClient(api_key="your_key", api_secret="your_secret", testnet=True)

# Market data
server_time = await client.get_server_time()
tickers = await client.get_tickers(category="spot")
klines = await client.get_kline("BTCUSDT", "1h", category="linear")

# Trading
await client.place_order({
    "category": "linear",
    "symbol": "BTCUSDT",
    "side": "Buy",
    "orderType": "Market",
    "qty": "0.001"
})

Requirements

• Python >= 3.12
• aiohttp
• High-performance connection pooling for production use

Performance Tips

1. Use Shared Session for applications creating many clients
2. Enable Caching for repeated API credential usage
3. Configure Connection Limits based on your throughput needs
4. Use Background Cleanup for long-running applications
