加代码在哪个位置
比如这个抢盘口策略
function CancelPendingOrders(orderType) {
while (true) {
var orders = _C(exchange.GetOrders);
var count = 0;
if (typeof(orderType) != 'undefined') {
for (var i = 0; i < orders.length; i++) {
if (orders[i].Type == orderType) {
count++;
}
}
} else {
count = orders.length;
}
if (count == 0) {
return;
}
for (var j = 0; j < orders.length; j++) {
if (typeof(orderType) == 'undefined' || (orderType == orders[j].Type)) {
exchange.CancelOrder(orders[j].Id, orders[j]);
if (j < (orders.length-1)) {
Sleep(Interval);
}
}
}
}
}

}

// 利润消失

CancelPendingOrders();
return;
}

if (LastBuyPrice > 0 && (ticker.Buy - LastBuyPrice) > SlidePrice) {

}

return;
}
