dvcrn VBrokers Trader
Automate trading on VBrokers (华盛通 VCL HK) via the OpenAPI Gateway running locally.
Prerequisites
- OpenAPI Gateway must be running locally (GUI app:
华盛通OpenAPIGateway.app) - Gateway URL:
http://127.0.0.1:11111 - AES key for password encryption: provided during account setup (see references/api-reference.md)
- Python packages:
pycryptodome(pip install pycryptodome)
Quick Start
Copy scripts/vbrokers_client.py to your project and import it:
import sys
sys.path.insert(0, '/path/to/skill/scripts')
import vbrokers_client as vb
# 1. Login (required after Gateway restart)
vb.trade_login("your_trading_password")
# 2. Check account
funds = vb.get_account_funds("P") # P=US, K=HK
# 3. Get real-time quote (use correct mktTmType for time segment)
quote = vb.get_quotes_batch(["AAPL"], session=-1) # -1=pre-market
# 4. Place order
result = vb.place_order("AAPL", "P", "1", 1, 180.00) # BUY 1 share limit $180
# 5. Check positions
positions = vb.get_positions("P")
Key Concepts
Request Format (Critical)
All HTTP requests must use nested params:
{"timeout_sec": 10, "params": {"exchangeType": "P", ...}}
Exchange Types
| Code | Market |
|---|---|
P |
US Stocks |
K |
HK Stocks |
v |
深股通 |
t |
沪股通 |
Session Types (for orders)
| Value | Meaning |
|---|---|
"0" |
Regular hours only |
"1" |
Extended (pre + post market) — use for US stocks |
mktTmType (for real-time quotes)
| Value | Segment | Beijing Time |
|---|---|---|
1 |
Regular (盘中) | 22:30–05:00 |
-1 |
Pre-market (盘前) | 17:00–22:30 |
-2 |
After-hours (盘后) | 05:00–09:00 |
-3 |
Night session (夜盘) | 09:00–17:00 |
| omit | Default (last close) | — |
⚠️ Always specify mktTmType for real-time prices — omitting it returns the previous close.
Password Encryption
Trading password must be AES-ECB encrypted before login:
# Already handled in vbrokers_client.py via encrypt_password()
# Key: base64-encoded 24-byte AES key (provided at account setup)
Common Workflows
Stop-Loss / Take-Profit Monitor
result = vb.check_stop_loss("AAPL", "P", cost_price=150.0,
stop_loss_pct=0.08, take_profit_pct=0.10)
# Returns: {"action": "hold"/"stop_loss"/"take_profit", "current_price": ..., "pnl_pct": ...}
if result["action"] == "stop_loss":
vb.place_order("AAPL", "P", "2", qty, 0, entrust_type="5") # market sell
Batch Quotes with Time Segment
from datetime import datetime, timezone, timedelta
bj_hour = (datetime.now(tz=timezone.utc) + timedelta(hours=8)).hour
# Determine correct mktTmType based on Beijing time
session = 1 if (bj_hour >= 22 or bj_hour <= 4) else -1 if bj_hour >= 17 else -2 if bj_hour <= 8 else -3
quotes = vb.get_quotes_batch(["AAPL", "TSLA", "NVDA"], session=session)
Cancel All Orders
vb.cancel_all_orders("P") # Cancel all pending US stock orders
