通过 MetaTrader5 python 模块发送开仓订单，但没有任何反应

Question

我在堆栈溢出中遵循了 Metatrader5 python documentation and this 答案

我尝试开空仓：

import MetaTrader5 as mt5


ea_magic_number = 9986989 # if you want to give every bot a unique identifier

def get_info(symbol):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5symbolinfo_py
    '''
    # get symbol properties
    info=mt5.symbol_info(symbol)
    return info

def open_trade(action, symbol, lot, sl_points, tp_points, deviation):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5ordersend_py
    '''
    # prepare the buy request structure
    symbol_info = get_info(symbol)

    if action == 'buy':
        trade_type = mt5.ORDER_TYPE_BUY
        price = mt5.symbol_info_tick(symbol).ask
    elif action =='sell':
        trade_type = mt5.ORDER_TYPE_SELL
        price = mt5.symbol_info_tick(symbol).bid
    point = mt5.symbol_info(symbol).point

    buy_request = {
        "action": mt5.TRADE_ACTION_DEAL,
        "symbol": symbol,
        "volume": lot,
        "type": trade_type,
        "price": price,
        "sl": price - sl_points * point,
        "tp": price + tp_points * point,
        "deviation": deviation,
        "magic": ea_magic_number,
        "comment": "sent by python",
        "type_time": mt5.ORDER_TIME_GTC, # good till cancelled
        "type_filling": mt5.ORDER_FILLING_RETURN,
    }
    # send a trading request
    result = mt5.order_send(buy_request)        
    return result, buy_request 

def close_trade(action, buy_request, result, deviation):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5ordersend_py
    '''
    # create a close request
    symbol = buy_request['symbol']
    if action == 'buy':
        trade_type = mt5.ORDER_TYPE_BUY
        price = mt5.symbol_info_tick(symbol).ask
    elif action =='sell':
        trade_type = mt5.ORDER_TYPE_SELL
        price = mt5.symbol_info_tick(symbol).bid
    position_id=result.order
    lot = buy_request['volume']

    close_request={
        "action": mt5.TRADE_ACTION_DEAL,
        "symbol": symbol,
        "volume": lot,
        "type": mt5.ORDER_TYPE_SELL,
        "position": position_id,
        "price": price,
        "deviation": deviation,
        "magic": ea_magic_number,
        "comment": "python script close",
        "type_time": mt5.ORDER_TIME_GTC, # good till cancelled
        "type_filling": mt5.ORDER_FILLING_RETURN,
    }
    # send a close request
    result=mt5.order_send(close_request)


# This is how I would execute the order
result, buy_request = open_trade('buy', 'USDJPY', 0.1, 50, 50, 10)
close_trade('sell', buy_request, result, 10)

没有任何反应，应用程序终端也没有任何反应。我还检查了 Metatrader5 中的贸易和历史部分以查找一些相关信息，但我一无所获。

如何监控Metatrader5中的日志来调试代码并解决问题？

Answer 1

在 MetaTrader 中，算法交易必须开启才能建立 buy/sell 头寸。

Answer 2

仅适用于达到此主题且算法交易按钮打开但发送订单时没有任何反应的人。

在我的例子中，这是因为我将请求的 'volume' 设置为整数，而且它必须是一个浮点数。没有显示错误，没有生命迹象，order_send(...) 返回 None 就是这样。只需将传入值转换为浮点数即可。

题主不是这样的，希望对以后有冒险精神的人有所帮助
