EXCHANGE

exchange

exchange 是一个交易所对象，也是在策略实盘设置、回测设置中添加的第一个交易所对象。所有与交易所的交互均通过该对象的成员函数实现。

类型

object

示例


    javascript
    
    
function main() {
    Log("First exchange object name:", exchange.GetName(), ", Label:", exchange.GetLabel())
}


    python
    
    
def main():
    Log("First exchange object name:", exchange.GetName(), ", Label:", exchange.GetLabel())


    rust
    
    
fn main() {
    Log!("First exchange object name:", exchange.GetName(), ", Label:", exchange.GetLabel());
}


    c++
    
    
void main() {
    Log("First exchange object name:", exchange.GetName(), ", Label:", exchange.GetLabel());
}

exchanges exchange.GetName exchange.GetLabel

exchanges

exchanges 是一个交易所对象数组，包含在策略实盘设置或回测设置中添加的所有交易所对象，其中 exchanges[0] 即为 exchange。

在策略实盘设置或回测设置中添加的交易所对象，将根据添加的先后顺序依次对应 exchanges[0]、exchanges[1]、exchanges[2]、…… exchanges[n]。

类型

array

示例


    javascript
    
    
function main() {
    for(var i = 0; i < exchanges.length; i++) {
        Log("Exchange index:", i, "Name:", exchanges[i].GetName(), "Label:", exchanges[i].GetLabel())
    }
}


    python
    
    
def main():
    for i in range(len(exchanges)):
        Log("Exchange index:", i, "Name:", exchanges[i].GetName(), "Label:", exchanges[i].GetLabel())


    rust
    
    
fn main() {
    for i in 0..exchanges.len() {
        Log!("Exchange index:", i, "Name:", exchanges[i].GetName(), "Label:", exchanges[i].GetLabel());
    }
}


    c++
    
    
void main() {
    for(int i = 0; i < exchanges.size(); i++) {
        Log("Exchange index:", i, "Name:", exchanges[i].GetName(), "Label:", exchanges[i].GetLabel());
    }
}
