otKey、otSecret

onetoken上生成的“我的OT Key”

accounts

交易所开通的账户 “交易所/账户名”

contract

交易所和交易对 "huobip/btc.usdt"

state

订单状态 active和end两种基本状态

count

订单成交记录数量

data

创建订单的参数
例如:

data := map[string]interface{}{
    "contract": acc.contract,
    "bs":       "b",
    "price":    3100,
    "amount":   0.03,
}

SDK的使用

详细例子见examples
用封装的restfull接口交易:

//创建订单
var acc1 = ot.Account{
    OtKey:    "",
    OtSecret: "",
    Accounts: "",
}
contract := "okex/btc.usdt"
data := map[string]interface{}{
    "contract": acc.contract,
    "bs":       "b",
    "price":    3100,
    "amount":   0.03,
}
ordermsg, err := acc1.CreateOrder(contract, data)
if err != nil {
    return "", err
}

用封装的websocket接口获取行情:

//获取实时tick数据
contract := "okex/btc.usdt"
tickData, err := quote.ContractsTick(contract)
if err != nil {
    fmt.Println("error:", err)
    return
}
