Market Data

Market Data

Fetches stock market data from TDX (通达信) protocol servers.

Real Code Reference

• tradinglearn/pytdx2/client/quotationClient.py — QuotationClient with get_KLine_data(), get_security_quotes(), etc.
• tradinglearn/pytdx2/client/baseStockClient.py — BaseStockClient socket layer with auto-retry
• tradinglearn/pytdx2/const.py — MARKET, CATEGORY, PERIOD enums, 43+ server hosts

Capabilities

• Real-time quotes: get_security_quotes() / get_security_quotes_details() (with 5-level depth)
• K-line (OHLCV) data: get_KLine_data(market, code, period, start, count) — 1min to yearly
• Market categories: Shanghai A, Shenzhen A, Growth Enterprise, Beijing A; futures, options, HK stocks
• Market overview: get_top_stock_board(category) — top gainers/losers/amplitude, get_index_info()

Typical Workflow

from pytdx2.client.quotationClient import QuotationClient
from pytdx2.const import MARKET, PERIOD

client = QuotationClient()
client.connect().login()
# Daily K-line for 平安银行
klines = client.get_KLine_data(MARKET.SZ, "000001", PERIOD.DAY, start=0, count=800)
# Real-time quotes for a batch
quotes = client.get_security_quotes(["000001", "000002"])
client.disconnect()

Notes

• K-line prices divided by 1000; quote prices divided by 100
• Always call client.disconnect() — sockets leak otherwise
• data_fetcher.py wraps this with retry logic and DataFrame normalization
