exchange.CancelOrder

exchange.CancelOrder()函数用于取消订单。FMZ平台的订单{@struct/Order Order}结构的属性Id由交易所品种代码和交易所原始订单Id组成，以英文逗号间隔。例如OKX交易所的现货交易对ETH_USDT订单的属性Id格式为：ETH-USDT,1547130415509278720。

调用exchange.CancelOrder()函数撤销订单时传入的参数orderId与订单{@struct/Order Order}结构的Id属性一致。

exchange.CancelOrder()函数返回真值（例如true）表示取消订单请求发送成功，返回假值（例如false）表示取消订单请求发送失败。返回值仅代表请求发送成功或失败，若要判断交易所是否已取消订单，可调用exchange.GetOrders()进行确认。 bool

exchange.CancelOrder(orderId) exchange.CancelOrder(orderId, …args)

orderId参数用于指定要取消的订单。 orderId true string 扩展参数，可以输出附带信息到该撤单日志中，arg参数可以传递多个。 arg false string / number / bool / object / array / any (平台支持的任意类型)

function main(){
    var id = exchange.Sell(99999, 1)
    exchange.CancelOrder(id)
}

def main():
    id = exchange.Sell(99999, 1)
    exchange.CancelOrder(id)

void main() {
    auto id = exchange.Sell(99999, 1);
    exchange.CancelOrder(id);
}

撤销订单。 “`javascript function main() { if (exchange.GetName().includes(“Futures_”)) { Log(“Set contract to: perpetual swap, set direction to: open long.”) exchange.SetContractType(“swap”) exchange.SetDirection(“buy”) }

var ticker = exchange.GetTicker()
exchange.Buy(ticker.Last * 0.5, 0.1)

var orders = exchange.GetOrders()
for (var i = 0 ; i < orders.length ; i++) {
    exchange.CancelOrder(orders[i].Id, "Canceled order:", orders[i])
    Sleep(500)
}

} python def main(): if exchange.GetName().find(“Futures_”) != -1: Log(“Set contract to: perpetual swap, set direction to: open long.”) exchange.SetContractType(“swap”) exchange.SetDirection(“buy”)

ticker = exchange.GetTicker()
exchange.Buy(ticker["Last"] * 0.5, 0.1)

orders = exchange.GetOrders()
for i in range(len(orders)):
    exchange.CancelOrder(orders[i]["Id"], "Canceled order:", orders[i])
    Sleep(500)```

”`cpp void main() { if (exchange.GetName().find(“Futures_”) != std::string::npos) { Log(“Set contract to: perpetual swap, set direction to: open long.”); exchange.SetContractType(“swap”); exchange.SetDirection(“buy”); }

auto ticker = exchange.GetTicker();
exchange.Buy(ticker.Last * 0.5, 0.1);

auto orders = exchange.GetOrders();
for (int i = 0 ; i < orders.size() ; i++) {
    exchange.CancelOrder(orders[i].Id, "Canceled order:", orders[i]);
    Sleep(500);
}

} FMZ的API函数中可以产生日志输出的函数，例如：Log()、exchange.Buy()、exchange.CancelOrder()等，都可以在必要参数后附加额外的输出参数。例如：exchange.CancelOrder(orders[i].Id, orders[i])，这样在撤销Id为orders[i].Id的订单时，会附带输出该订单的信息，即orders[i]“`这个{@struct/Order Order}结构。

如果使用较旧版本的托管者，exchange.CancelOrder()函数的参数orderId可能与当前文档中描述的orderId有所不同。
