Overview

Package tdx provides a minimal Go client for the TDX (通达信) 7709 market data protocol.

Quick Start 

c, err := tdx.Dial("110.41.147.114:7709")
if err != nil { ... }
defer c.Close()

klines, err := c.GetKline("sh600000", "day", 10)
if err != nil { ... }
for _, k := range klines {
    fmt.Printf("%s O=%.3f H=%.3f L=%.3f C=%.3f V=%d\n",
        k.Time.Format("2006-01-02"), k.Open, k.High, k.Low, k.Close, k.Volume)
}
