您好，这个报错一般是由于开始没有设置合约，您使用exchange.SetContractType设置合约试下。

合约使用swap 试下。 ```js function main() { Log(exchange.GetName()) exchange.SetContractType("swap") return exchange.GetTicker() } ```

exchange.SetContractType("XBTUSD") 以前可以用，现在这样设置读取不出来

function main() { exchange.SetContractType("XBTUSD") Log(_C(exchange.GetAccount)) // Log(_C(exchange.GetTicker)) // Log(_C(exchange.GetDepth)) // Log(_C(exchange.GetRecords)) // Log(_C(exchange.GetTrades)) // IO Test // Log(_C(exchange.IO, "api", "GET", "user/affiliateStatus")) // Log(_C(exchange.SetMarginLevel, 10)) /* exchange.SetDirection("buy") var orderId = exchange.Buy(-1, 3) if (orderId) { Log(_C(exchange.GetOrder, orderId)) }*/ Log(_C(exchange.GetPosition)) }
