Например, если вы используете Exchange, вы можете использовать SetMaxBarLen (500) или SetMaxBarLen (500), но в начале вы можете использовать только 200.

测试可以的，你看下是不是你回测上设置了。


            
            
            
def main():
    # exchange.SetContractType("quarter")
    exchange.SetMaxBarLen(500)
    while True :
        Log(len(exchange.GetRecords()))
        Sleep(1000)
        break
