我正在尝试在 okex 交易所版本 5 上使用 ccxt 创建一个永久限价订单。该 API 已成功在现货交易所下订单（限价和市场订单），但不是在永续交易上。这是我正在尝试的 -

exchange_swap = ccxt.okex5({
'apiKey': credentials['okex']['apikey'],
'secret': credentials['okex']['secretkey'],
'password': credentials['okex']['password'],
'options': {
    'defaultType': 'swap', 
      }
})
params =  {
   "test":True
}
order = exchange_swap.createLimitBuyOrder('XRP-USDT-SWAP',100,0.7)

错误信息-

ccxt.base.errors.BadRequest: okex5 {"code":"1","data":[{"clOrdId":"","ordId":"","sCode":"51000","sMsg":"Parameter posSide  error ","tag":""}],"msg":""}

在搜索了这个错误之后，我在他们的文档中发现了这个 -

Error message           Http status code     Error code
Parameter {0} error.    400                  51000

PS - 我可以通过 okex 上的交易仪表板而不是通过 API 来放置它。我有足够的余额来创建这个订单。

整个错误信息是这样的——
